Upgrade Gemini LLM and TTS Models

[aidivas]

Hello...can you advise of extra code changes needed to upgrade gemini tts to 2.0 and 2.5...1.5 pro is going away thanks

FYI

You can just update the LLM model ONLY and it will work as before e.g. gemini 1.5 pro > gemini 2.5 pro. All tested and works great.

This change is made in config.yaml

This uses the gemini voices you have configured for gemini in conversation_config.yaml

If you want to use the new gemini TTS models theres a lot more work involved. - i dont have the gemini tts models working yet after much testing and a lot of code credits!!

• Adding a new TTS model requires multiple steps:

  • You need to add the model script to the TTS providers folder
  • You need to register it in the factory.py file
  • You need to make sure the API key handling works correctly

• The TTS models are separate from the LLM:

  • The LLM generates the transcript text
  • Then the TTS model converts that text to speech
  • They're independent systems that work in sequence
