AI Avatar
An AI avatar is a digital character or persona that autonomously moves, speaks, and responds using artificial intelligence. Unlike conventional avatars, its conversations, expressions, gestures, and overall presentation are controlled in real time by AI. Combining technologies such as text-to-speech (TTS), facial motion capture, and natural language processing (NLP), AI avatars can converse with emotion and return appropriate answers to questions. Integration with generative AI has enabled even more natural and expressive AI avatars in recent years. Key use cases: • Online customer service and AI receptionists (e.g., automated responses on store websites) • Virtual influencers and YouTubers (e.g., AI characters creating and publishing content) • Interactive characters in the metaverse and video games • Conversational support and simulation training in education and healthcare Services that generate an AI avatar that looks and sounds just like the user—based on their own photo or voice—have also emerged, and are used for SNS profile videos, presentations, and narration stand-ins. Positioned as a "digital twin that can talk, move, and respond," AI avatars are attracting attention across entertainment, business, and education, and are expected to evolve into increasingly realistic, feature-rich presences.
