ChatGPT Assistant

A voice2voice chatgpt assistant
Constructed by using OpenAI Whisper + OpenAI ChatGPT API + Google Text2Speech Service

Introduce

• Speech2Text through OpenAI's Whisper Model (currently using local CPU)
• Chat with ChatGPT through its API
• Text2Speech through Google's Text2Speech Service

News

• 2023/03/26:
  • Replace sox with pydub for playing the speech from Google
  • Move the prompting from system to user role, which is more effective
• 2023/03/12:
  • SIMPLE WebUI support for chat history with automatically websocket notification
  • Mute the code blocks before get into text2speech service
• 2023/03/07:
  • We can now ask ChatGPT to reset the session for us. Therefore it will clear out the current session, preventing spend the quota on unrelated history messages.
  • Use PyAudio instead of using arecord/lame which is only available for specific platform

Known Issues:

• 2023/03/12:
  • Code blocks might be corrupted, if it contains "\n" "\t"
  • Websocket active notify has large delay. Don't know why... need time to survey
