I had no idea you could do something like this through the Pebble!
replyI pre-ordered mine last year but it looks like it's not going to come before September :(
As soon as it gets here I think this is the first project I'm going to attempt. It'll be helpful you've got any resources or source code for the Pebble STT and TTS parts. (I already have my own hermes that I want to hook it up to)
The Pebbble transcription is part of their SDK and very easy to use programmatically, also it's quite accurate (not perfect but good enough that I turned confirmation off).
replyThe TTS is Piper installed on the same VPS as Hermes.
Happy to answer questions or share code. I might publish the device app eventually. I hope your Pebble arrives soon, it's a great device.
