The AI-Based Talking Avatar project integrates cutting-edge technologies to create a lifelike virtual assistant capable of engaging in meaningful conversations. This interactive system leverages advanced AI models to generate natural responses, convert text to speech, and visually synchronize mouth movements, providing a seamless and immersive user experience.
How It Works
- Response Generation: At the core of the system is ChatGPT, which is employed to generate contextually relevant and engaging responses. By defining specific roles, the AI can tailor its language and tone, enhancing the conversational experience for users.
- Text-to-Audio Conversion: Once a response is generated, it is sent to a Text-to-Audio API service. This technology converts the written text into natural-sounding speech, allowing the avatar to “speak” in a way that feels authentic and relatable.
- Viseme Synthesis: To add realism to the avatar, we utilize the Synthesis-Viseme service from Azure. This service analyzes the generated audio and creates corresponding visual representations of mouth movements (visemes), ensuring that the avatar’s lip syncs accurately with the spoken words. This synchronization enhances the overall believability of the interaction.
