On a local environment the speech detection was not working, leading to the "teach omi your voice" being present all the time.

  • The silero model was not returning segments as it needs 16000Hz and not 8000Hz
  • The code was hardcoded to look for a seperate vad service which can be configured in backend/modal

This PR:

  • Fixes silero model use
  • Adds logic to fallback to silero if the HOSTED_VAD_API_URL is not set
  • Simplified the docker container to import the nvidia cuda image directly instead of building from scratch
  • Changed default vad port so doesn't conflict with server
  • Updated the code to call the correct /v1/vad endpoint instead of root
  • Added logic to either be able to give the google service account as a file or a json string
  • Updated docs
  • Updated a couple of libraries that were failing on the ios app build

@thestumonkey
added support to read service account from json file
