MultiRoombaRover/plans/audio_on_roomba_outline.md

general idea

• the pi on each roomba will have a speaker and microphone
• alsa devices
  • they are both the default audio device
• you will have to modify roverd, the pi install script, and the server to get this all to work

adding stuff to installation script

• I am using the google voice AIY v1 kits for audio
• boot config stuff
  • enable dtoverlay=googlevoicehat-soundcard
  • disable dtparam=audio=on
• copy asound.conf in pi folder to /etc/asound.conf

microphone

• add microphone to the SRT publish stream

speaker

• user's chat messages will be TTS'ed through the speaker on the pi
  • either flite with a way to choose the voice
  • or espeak where you can choose the pitch
• on the web UI and in the chat API
  • add new stuff to chat
    • only shows up if you are on a rover
    • only shows up if TTS is enabled on that rover
  • people can choose between flite or espeak
    • if they choose flite, they can choose the voice from the default flite voices (exclude awb and awb_time)
    • if they choose espeak, they can choose the pitch. Have a dropdown with increments of 10 from 0 to 99
