ABSTRACT
Video conferencing has become an essential tool for communication in both
professional and personal settings, especially highlighted by the global shift towards
remote work and online collaboration. The integration of Artificial Intelligence (AI)
into video conferencing applications has significantly transformed these platforms,
enhancing user experience, improving efficiency, and providing advanced
functionalities that were previously unimaginable.
This paper explores the various ways AI is being integrated into video conferencing
applications. Key AI-driven features include real-time noise suppression, virtual
backgrounds, automated transcription, facial recognition, and emotion analysis. These
advancements aim to improve audio and visual quality, ensure privacy, and provide
more engaging and productive meetings.
Furthermore, AI-driven analytics offer valuable data on participation and engagement,
helping organizations to optimize their meeting strategies. This includes features like
automated attendance tracking, speaker statistics, and sentiment analysis of the
conversations.
The integration of AI in video conferencing also raises concerns about privacy and data
security. This paper discusses the ethical implications and the need for robust data
protection measures to safeguard user information.
In conclusion, AI is revolutionizing video conferencing by making it more intuitive,
efficient, and secure. The continued development and ethical implementation of AI
technologies promise to further enhance the capabilities of video conferencing
applications, making them indispensable tools for future communication needs.
