+# 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
