Introduction
In recent years, Multimedia Learning has become an increasingly popular method for educational and research purposes.With the rise of digital technologies and the internet, multimedia has become essential for disseminating information and engaging learners in various fields.Multimedia Learning combines different media formats like text, images, audio, and video to create a rich and engaging learning experience.Multimedia Learning offers several advantages over traditional teaching methods.It can provide learners access to a wealth of information and resources that are not available through conventional methods.Multimedia Learning can also be tailored to each learner's individual needs and learning styles, making it a more accessible and practical approach to learning.This can lead to increased engagement, motivation, and achievement, as learners are more likely to retain information when it is presented in a way that is visually and emotionally appealing.Education 4.0 is a new educational approach that focuses on preparing learners for the digital age, and its primary aim is to revolutionize the future of education by leveraging advanced technology and automation.Education 4.0 is a new paradigm in education that reflects the rapid changes and technological advancements of the Fourth Industrial Revolution (Industry 4.0).It represents a shift away from traditional models of education towards a more personalized, flexible, and technology-enhanced approach.Education 4.0 integrates advanced technologies, such as Artificial Intelligence (AI), big data, Internet of Things (IoT) and Augmented Reality (AR), into learning.These technologies can facilitate the development of new teaching methods and pedagogies that can better meet the needs of learners in the digital age.The COVID-19 pandemic has significantly impacted the educational landscape, compelling instructors to depend on technology for virtual instruction.The integration of Education 4.0 has the potential to enhance learning and teaching, facilitating the education sector's evolution to the advantage of both students and teachers.Educators' time on administrative tasks can be significantly reduced by applying Education 4.0 for learning education and automating activities like grading and assessments (Amerstorfer, 2018;Narke, 2021).
By automating administrative tasks, teachers can dedicate more time to their students to enhance the learning experience (Ranjan et al., 2021).Integrating artificial intelligence and machine learning into education can facilitate the adaptation of learning and enable students to stay current with the latest developments.This emphasizes equipping students with the skills necessary to confront and resolve challenges.Traditional educational models must be reassessed from a forward-looking perspective to stay pertinent.Students must be empowered to acquire the skills necessary to keep up with rapidly evolving technology, and they should receive mentorship rather than mere instruction.Information should be presented as a resource rather than enforced upon them.Comprehensive and vocational education should strive to equip students with the abilities they need to thrive in the job market.The objective of utilizing Education 4.0 in the realm of education is not to substitute instructors but rather to support them in comprehending each student's potential and limitations more effectively.Integrating technology into the curriculum, modifying the learning process and utilizing technology can enhance the learning progress.In the classroom, teachers can utilize Education 4.0 tools to enhance the quality of instruction provided to students and make the learning experience more engaging and exciting.Using well-crafted Education 4.0 tools allows teachers and students to benefit from technological advances that can enhance new educational methods.Implementing AI-powered tools enables teachers to improve students' academic performance and strengthen their critical thinking abilities.Immediate feedback is advantageous for students as it allows them to pinpoint their weaknesses and take steps to improve their learning.Education 4.0 have the potential to make learning universally accessible for all students, regardless of geographical location, by employing a universal language.
ELSA (English Language Speech Assistant) is one of the applications and adopts Education 4.0 for enhancing language skills.ELSA is designed as a fun way of teaching English pronunciation with the help of AI.ELSA's artificial intelligence technology was developed using voice data of English-speaking people with various accents.This allows ELSA to recognize the speech patterns of L2 speakers, setting it apart from most other voice recognition technologies.ELSA for business allows the students to enhance the students' Professional English Communication skills among Business school students.According to the reviews, ELSA is listed in the top five Apps (2023) for enhancing communication skills worldwide (Dhivya et al., 2023).
English is widely acknowledged as a globally renowned language, making it a predominant language in business.Knowing English can be beneficial in many ways, whether you want to advance professionally or just for personal enjoyment.The advent of the internet has opened up numerous avenues for exploring fresh opportunities and expanding one's knowledge of Professional English Communication.Professional English is the language utilized in diverse professional domains like business, academia, law, medicine, engineering and more.It involves using specialized vocabulary, jargon and technical terms relevant to a particular profession or industry.Utilizing professional English demands expertise in the specialized jargon of the respective profession and the broader English language.Within the realm of Professional English, Business English holds particular significance as it caters to the unique requirements of business school students and professionals, enabling them to communicate in business and commerce domains effectively.It is often referred to as the international language of business, which is becoming increasingly accurate as international trade expands and more countries interact (Marchman et al., 2017).To secure a position in a top multinational company, a certain level of English proficiency is often required, which is why more and more people are learning English.Even if you already have a basic understanding of English, acquiring knowledge of Professional English can help you master professional terminology and possibly lead to new career prospects (Narke, 2021).Learning Professional English enables learners to enhance their language proficiency, specifically in terms of communication in an office or other corporate setting (Thavabalan et al., 2020).As you become familiar with the communication demands of the workplace, you can gain the self-assurance to establish robust relationships with your co-workers and customers.Mastering Professional English Communication is crucial for advancing anyone's career (Crowther et al., 2015).Improving the professional business vocabulary and knowledge will help anyone to work more effectively and open new career opportunities.
In this research, the researchers will explore the potential of combining Multimedia Learning by adopting the Education 4.0 tool, ELSA, to enhance Professional English Communication.It examines the benefits of incorporating technology into language education and discusses how Education 4.0 tools can be effectively utilized to improve communication skills in a professional context.

Multimedia learning and teaching
Multimedia Learning entails the utilization of diverse media forms, including images, videos, audio, text, and graphics, to enrich the educational process.This approach finds application in various contexts, spanning in-person classrooms, online courses, and self-directed learning environments (Mayer, 2014).Multimedia can provide multiple forms of information that can be processed by different brain parts, leading to better retention and recall of information.Various forms of Multimedia Learning comprise visual learning through images and videos, auditory education involving sound and music, and kinesthetic learning involving hands-on activities and simulations (Alobaid, 2020).Multimedia Learning includes interactive e-books, online tutorials, educational videos, and multimedia presentations (Srivani & Hariharasudan, 2023).Many educational apps and games also incorporate multimedia elements to create engaging and interactive learning experiences.Many studies show that learning a language with the help of multimedia tools gains more advantages (Ziegler et al., 2017).Audio and videos assist students in understanding the concepts well.Multimedia provides many learning tools using technology and gives language learners insight into improving their communication skills.Therefore, it is necessary to look into the relevant theories for learning through multimedia.Cognitive skill is vital for adopting effective learning using technology (Eady & Lockyer, 2013).Cognitive skills are the core skills that the brain uses to think, read, learn, remember, reason and pay attention.Working together, they take incoming information and move it into the bank of the student's knowledge (Srivani et al., 2022).Many studies show positive results in Multimedia Learning by adopting pictures, audio and videos than words (Mayer, 2014).Different pedagogy methods are used for enhancing students' communication skills, and the study also listed the number of digital tools used for enhancing the student's communication skills (Abdulrahaman et al., 2020).Another study points out that multimedia technology and learning are adopted for many educational purposes for enhancing skills.Teachers need to be refurbished with the skills to implement the technology better.Thus, adopting proper ICT tool transform teacher-centred, student centre-learning into colearners (Coleman et al., 2016).

Education 4.0
Education 4.0 supports the system in which students can learn from the multimedia platform using current technology.Education 4.0 is an innovative and technology-driven approach to education that seeks to provide students with a more personalized and interactive learning experience.It is characterized by the integration of emerging technologies, such as artificial intelligence (AI), virtual and augmented reality (VR/AR), and the Internet of Things (IoT), into the traditional educational system (Haderer & Ciolacu, 2022a).
It represents a transformative approach to learning that harnesses the power of technology and innovation to reshape traditional education (Haderer & Ciolacu, 2022a).Students in this era benefit from personalized learning experiences tailored to their needs and interests, while collaborative environments foster cross-cultural communication and teamwork (Gajek et al., 2022).Emphasizing critical thinking and problem-solving skills, Education 4.0 ensures students are well-equipped to navigate the complexities of the modern world.Unlike in-person and online learning, this model offers flexibility and accessibility to educational resources (Goldin et al., 2022).Technological fluency is a key focus, enabling students to leverage digital tools effectively.With a global perspective and continuous assessment, Education 4.0 prepares students to become responsible global citizens who thrive in a rapidly changing job market, as curricula align with industry needs (Srivani & Hariharasudan, 2020).Moreover, immersive technologies, such as virtual reality and augmented reality, offer lifelike simulations, enriching the learning experience.All in all, Education 4.0 stands as an exciting paradigm shift, empowering learners to acquire knowledge, skills, and attitudes that drive lifelong learning and success in the 21st century (Oliveira & Saraiva, 2023).
Incorporating Education 4.0 in higher education gains leverage students to enhance their knowledge.Education 4.0 adopts competency-based education, and it depends mainly on the knowledge skills of the learners.The four main components of Education 4.0 are competency, learning methods, information and communication technology and infrastructure (Miranda et al., 2021).
• Academic institutions and organizations have defined competencies that must be promoted: critical thinking, collaboration, communication and creativity.
• Learning methods, such as task-based methods, must be followed.New learning methods, activities and tools emerged from training should develop the competencies.
• Many technologies, such as Virtual Reality (VR) platforms, flipped classrooms, etc., must be incorporated.
• Universities and institutions must adopt the necessary facilities for implementing Education 4.0 among students.This will enhance the student's knowledge as well as better career opportunities.
In addition, Education 4.0 allows students to learn according to their personal choice and receive a customized learning experience (Qureshi et al., 2021).However, experts are required to take them to the next level.Hence, teachers must be enriched with current knowledge and well-versed in technology to implement Education 4.0 (Wallner & Wagner, 2016).This will enhance the creative teaching ability of the teachers.By providing comprehensive and up-to-date training in Education 4.0, teachers can better adapt their teaching methodologies to the rapidly evolving educational landscape (Aydın & Uştuk, 2020).This approach will enable them to effectively leverage modern technologies and innovative teaching tools to engage students and foster a deeper understanding of complex subjects.Moreover, investing in teacher training for Education 4.0 will empower educators to confidently navigate digital platforms and integrate cutting-edge resources into their lesson plans (Pastore et al., 2019).This, in turn, will create a more dynamic and interactive learning environment, catering to the diverse needs of today's tech-savvy students.
Furthermore, strengthening teachers' performance ability through specialized training will result in a higher quality of education, preparing students to thrive in an increasingly globalized and technology-driven world (Zoghbor, 2018).It is a strategic step towards equipping educators and learners with the skills and knowledge required to excel in the educational landscape of the future (Matsumoto-Royo & Ramírez-Montoya, 2021).Teachers also design a comprehensive teaching capacity-building program that links training with career development (Haderer & Ciolacu, 2022a).Overall, Education 4.0 represents a significant shift in how we think about education, as it seeks to leverage the power of technology to create a more engaging, interactive, and practical learning experience for students.

ELSA (English Language Speech Assistance)
ELSA is an application that supports Education 4.0 and helps to enhance learners' communication skills.It is an AI-powered mobile application that allows users to improve their English pronunciation and speaking skills.The app uses speech recognition technology to analyze users' pronunciation and provides feedback and suggestions for improvement.ELSA has a database of over 4,000 commonly pronounced English words and phrases, and it offers personalized lessons based on users' individual needs and goals.The app is available for download on both iOS and Android devices.ELSA is in the top five Apps (2023) for learning English (Pikhart, 2021).ELSA will help the learners pronounce the word, phrase and sentence ideally by giving the learner a score for their pronunciation.Many studies have proved that learners' communication skills have developed with the help of the ELSA application (Francisco, 2021).Moreover, ELSA teaches lessons in a fun way and allows the learners to connect by collaborating with fellow students all over the world (Pikhart, 2020a).Study sets in ELSA help to enhance the learner's LSRW skills for learning Professional English Communication.ELSA for business allows the learners to learn the vocabulary related to the business environment and make them communicate fluently.The study points out that the learner's fluency, grammar, vocabulary and comprehensibility are enhanced drastically with the help of the Education 4.0 application ELSA (Kholis, 2021).

Professional English Communication among the business school students
In the contemporary business landscape, confidence and robust communication skills are essential (Veda & Veda, 2019).In this globalized era, English stands as the paramount language, bridging communication gaps worldwide and facilitating seamless corporate interactions (Thavabalan et al., 2021).Companies must prioritize hiring individuals with exceptional abilities, particularly in understanding and mastering English, to achieve their goals of participating in the international business world and effectively utilizing human resources (Pikhart, 2020b).However, Professional English is a subset of English that concentrates on the language commonly employed in the corporate environment (Carrió-Pastor & Skorczynska, 2015).It is a part of the skill set for entering into the international business community.Effective communication in Professional English is crucial for success in today's globalized business world, as it allows individuals and organizations to communicate effectively with partners, clients and colleagues from different linguistic and cultural backgrounds (Dina & Ciornei, 2015).L2 English speakers see the importance of studying Professional English to improve their professional success.Professional English aims to enhance your ability to communicate effectively and facilitate clear and concise communication with English-speaking countries or organisations in a workplace or professional setting (Bhatia & Bremner, 2012).Due to the pandemic, many organizations relayed on the internet to enhance their business performance.Hence, knowledge of business vocabulary is mandatory for anyone entering the job market (Rafafie, 2021).By improving language skills, the employee can confidently present themself more professionally.Therefore, universities need to enhance students' language skills to prepare them for the workforce (Krepel et al., 2021).Teachers must adopt new techniques and conduct activities to improve the learners' language skills.Collaborative learning flipped classrooms, Paired Associate Learning (PAL), and many such teaching techniques were used to enhance their Professional English Communication skills (Krepel et al., 2021).As per the viewpoint of management faculties in India, improving Professional English Communication skills is considered crucial for securing indispensable job opportunities.Nevertheless, the necessary competencies in management schools seem to be diverging from the required learning skills.Therefore, universities must ensure the student's skills before entering the job market, and implementing a curriculum incorporating technology will make the students learn the necessary skills.
This study aims to examine the impact of Education 4.0 on the development of Professional English Communication skills among Business school students through the use of the ELSA application.Specifically, the study aims to evaluate the effectiveness of the ELSA application as a tool for improving Professional English Communication skills and to investigate how Multimedia Learning and Education 4.0 technologies can be used to enhance language learning outcomes.A cross-sectional survey was administered to students, and the resulting data were analyzed using IBM SPSS Statistics version 21.The Business School students of Tamil Nadu, India's southern region, were selected based on the purposive sampling technique.The collected data were analysed using descriptive statistics.

Discussion
Technology plays a significant role in developing language skills.Incorporating appropriate learning methods and techniques improves student skills and promotes sustainable environments.The current study investigates how Multimedia Learning and the Education 4.0 tool, specifically ELSA, help students enhance their Professional English Communication Skills.Table 13 shows the findings of the study attempt to answer all the research questions with evidence from real-time performance.
The results obtained reveal interesting insights into the participants' perceptions regarding various aspects of Education 4.0 and its impact on Professional English Communication skills.It is evident that a significant proportion of participants (29.6%) strongly agreed that Education 4.0 serves as a valuable platform for connecting people worldwide to enhance their proficiency in Professional English Communication.This finding highlights the potential of Education 4.0 in breaking down geographical barriers and fostering a global learning community, and the results of the current study align with the previous finding by using Education 4.0 (Srivani et al., 2022).Moreover, the second highest response (23.8%) of participants strongly agreed with the notion that Multimedia Learning and Education 4.0 tools, specifically ELSA, can facilitate personalized and adaptive learning, underscores the importance of incorporating technology-driven approaches in language education and the result of the study is parallel to the previous finding that stressed the importance of integrating technology for learning Business English Communication.Furthermore, the third highest response (22.8%) indicates strong agreement with the statement that Education 4.0 enables practical assessments to enhance students' Professional English Communication skills according to the learner's level and highlights the importance of practical application and skill development in language learning.The positive reception of the adaptive learning tool ELSA indicates that participants recognize the benefits of tailor-made learning experiences to suit individual needs and learning styles.Integrating practical assessments in Education 4.0 can potentially lead to more meaningful and effective learning outcomes in terms of language proficiency and supports the previous study, which recommended using AI tools for enhancing language learning (Haderer & Ciolacu, 2022b).Education 4.0 represents a new era in how education is delivered and received, and it helps enhance the learner's skills with the help of technology (Mohamad Alakrash & Abdul Razak, 2020).Likewise, the current study enhanced the Professional English Communication of the students using Education 4.0.The previous studies highlight the importance of learning techniques through remembering, recalling and retaining the words in the proper environment for language learning (Miranda et al., 2021;Moscardo et al., 2013).However, in the current study, Education 4.0 is used to remember, recall and retain words and enhances the student's Professional English Communication skills.
Furthermore, the preceding study (Peedikayil et al., 2023) highlighted using gaming technology to enhance learners' communication skills through mobile games.In contrast, the present study focuses on Education 4.0 as a catalyst for stimulating students' creativity via word games, allowing them to explore and incorporate a plethora of new words in a real-life context.According to previous research, technology's primary requirement is the presence of creative thinkers who possess the ability to generate original and innovative ideas (Rus, 2020).The notion that creative thinkers can express novel, unique, and even unconventional ideas is further reinforced.A notable distinction in creative thinking skills has been observed between students engaged in steam-based blended learning and those participating in conventional learning (Putri et al., 2023).However, in the current study, Education 4.0 emerges as a facilitator for nurturing students' creative thinking abilities and language proficiency.This implies that integrating cutting-edge technological approaches in education can unlock new dimensions of creativity while concurrently enhancing linguistic aptitude.
A study by Ibrahim shows Education 4.0 helps students learn easily and get experts in the field (Ibrahim et al., 2015).However, the current study shows Education 4.0 not only makes students learn easily but also brings several other benefits, such as personalization, accessibility, collaboration and career readiness among the participants.A study shows that Education 4.0 tools, such as AI-incorporated mobile applications, are used to enhance students' communication skills anywhere (Haderer & Ciolacu, 2022a).similarly, in the current study AI in ELSA app was used to enhance students' Professional English Communication skills.The earlier research stresses the importance of self-based education for learning a language (Teodorescu, 2015); meanwhile, the current study proves that Education 4.0 adopts self-based learning, and these mobile applications pave the way for that.Another study stressed the importance of practical lessons in mobile applications to make the student learn and use the skills in the appropriate places (Zulherman et al., 2023), but in the current study, study sets in the ELSA app were used to enhance the learners Professional English Communication skills.A subsequent study points out that rewards make the students stay consistent in using the application (Wijaya et al., 2020); similarly, the current study used a streak reward system to make the students consistently use the application.The previous research proves that the Education 4.0 tools Duolingo, Busuu, etc., enhance Communication skills (Bojovic, 2010), but the current study focused on ELSA for learning communication skills.Additionally, the present research stressed the importance of Professional English Communication skills.
The collection of studies stressed the importance of multimedia tools for learning a language through the test techniques with audio, videos and pictures (Anaelka, 2018;Fleaca & Stanciu, 2019;Haderer & Ciolacu, 2022a, ;Wallner & Wagner, 2016), but the findings of the current study not only replicate those of previous studies but also offer new insights into the underlying mechanisms.The current study's findings suggest that ELSA's effectiveness is mainly attributed to its interactive and personalized learning approach, which allows learners to engage in real-life communication scenarios and receive immediate feedback on their performance.This personalized approach enables learners to identify their weaknesses and strengths and work on them accordingly, resulting in better communication skills.Another study shows ELSA effectiveness can be improved drastically while learning Business English communication (Bhatia & Bremner, 2012), but the current study focuses and enhanced Professional English Communication of the students using the ELSA app and proves that the AI in the ELSA app access the pronunciation skill of the students and makes the students pronounce the word correctly.The findings of the earlier studies enhanced the learner's communication skills through planning, acting and observing techniques (Eady & Lockyer, 2013), but in the current research, technology such as AI was used to enhance Professional English Communication skills.Also, ELSA keeps track of the learner's activity and rewards them after finishing a level.It helps the learners check and keep using the application consistently.Moreover, ELSA helps connect with people worldwide and makes the students communicate with L1 speakers to practice their language skills.The cognitive theory of Multimedia Learning, developed by Richard E. Mayer, suggests that learners can process information more effectively when presented in multiple modalities and that the spatial and temporal contiguity effects can facilitate learning (Mayer, 2014).The current study supports the cognitive theory of Multimedia Learning combined with Education 4.0 for enhancing learners' language skills.In line with the earlier study, audio/video lessons make the students remember the lessons easily (Anaelka, 2018;Fleaca & Stanciu, 2019;Haderer & Ciolacu, 2022a, ;Wallner & Wagner, 2016) and the current study supports that by using multimedia applications to enhance language learning.Using multimedia resources, such as video tutorials and interactive quizzes, can provide a more engaging learning experience for students (Abdulrahaman et al., 2020;Narke, 2021), and the current study follows Multimedia Learning combined with Education 4.0 and shows enhanced learning outcomes and the primary opportunities for using this technique are to enhance student engagement and interactivity in learning Professional English Communication.ELSA, in particular, can offer immediate feedback on pronunciation and grammar, allowing students to improve their speaking skills in real time.Another opportunity of using Education 4.0 is the ability to provide greater flexibility regarding learning location and time (Mayer, 2008).Similarly, current show that students can access Multimedia Learning resources and Education 4.0 tools from anywhere, anytime, allowing them to fit their language learning and other commitments.
Many studies have been conducted in Multimedia Learning and Education 4.0 tool ELSA, but only a few studies have been conducted in Professional English Communication.The current study focuses on the importance of combining Multimedia Learning and the Education 4.0 tool; specifically ELSA, to enhance Professional English Communication.The novelty of the study highlights the importance of personalized and interactive learning approaches, gamification, and integration with other Education 4.0 approaches to enhance learners' motivation, engagement, and learning outcomes.

Conclusion
In conclusion, the study on the impact of the Education 4.0 tool ELSA on Professional English Communication among Business school students has demonstrated the potential of Education 4.0 tools to improve language learning outcomes significantly.The results indicate that the personalized and self-directed learning experience provided by ELSA has motivated students to learn Professional English Communication and increased their confidence and fluency in the language.The study also highlights the importance of peer learning and collaboration facilitated by Education 4.0 tools in enhancing students' Professional English Communication and language skills.Furthermore, the study underscores the importance of multimedia in English Language Teaching (ELT) and the need to adopt Education 4.0 tools to create a more sustainable and accessible environment for language learning.Overall, the findings suggest that adopting Education 4.0 in ELT can create a more sustainable and accessible environment for language learning, providing equal opportunities for all students regardless of their location or socioeconomic status.The findings of this study have several implications for English language teaching sectors, including the need for incorporating Education 4.0 tools in language teaching to create a more engaging, personalized, and effective language learning experience.Based on the findings of the study, the following were recommended for improvements.In a technology-driven society, the curriculum demands different pedagogies, and these pedagogies differ according to content, and technology brings sustainability to knowledge or education.Moreover, educational institutions can adopt Education 4.0 and implement the facilities for adopting 4.0 to create a sustainable environment.
However, integrating Multimedia Learning and Education 4.0 tool ELSA yields valuable insight, but it is crucial to consider its limitations.Technical difficulties, such as connectivity issues and software compatibility, can be significant barriers to effectively using these tools.Instructors may also need to adapt their teaching methodologies to ensure that students are not distracted by multimedia and that personalized learning experiences are effectively delivered.The study did not measure the long-term impact of using Education 4.0 tools on language learning outcomes or the transferability of the acquired language skills to real-life situations.In summary, while integrating Multimedia Learning and Education 4.0 tools like ELSA presents several opportunities for Professional English Communication, some challenges must be addressed to ensure that these tools are effectively used and fully leveraged to improve learning outcomes and highlights the need for further research in this area.
