Using custom models with rigged hair and two different hairstyles. See Appendix E for more details.
[<img src="images/screenshot4.jpg" width="200"/>](https://youtu.be/OA6LBZjkzJI) | I chat with Jenny and Harri. The close-up view allows you to evaluate the accuracy of lip-sync in both English and Finnish. Using GPT-3.5 and Microsoft text-to-speech.
[<img src="images/screenshot5.jpg" width="200"/>](https://youtu.be/fJrYGaGCAGo) | A short demo of how AI can control the avatar's movements. Using OpenAI's function calling and Google TTS with the TalkingHead's built-in viseme generation.
[<img src="images/screenshot6.jpg" width="200"/>](https://youtu.be/6XRxALY1Iwg) | Michael lip-syncs to two MP3 audio tracks using OpenAI's Whisper and TalkingHead's `speakAudio` method. He kicks things off with some casual talk, but then goes all out by trying to tackle an old Meat Loaf classic. 🤘 Keep rockin', Michael! 🎤😂
