tryng to fix Jasper on Rasberry Pi 3 Model B

[Alex S.]

Trying to get Jasper to work on my Rasberry Pi and microphone hooked up has been a very frustrating process. I've had problems with Jasper's outdated instructions with typos on their website, Howchoo's inadequate installation instructions, installing the newest version Phonetisaurus, errors from ALSA, pulseaudio getting in the way, Jasper's voice not coming on, etc. As of now, when I thought I had fixed all those issues I still get problems when starting up Jasper that I still don't understand.

I am using espeak tts and pocketsphinx stt.

I am having the same problem, so unfortunately I can't help you but if you find a solution I would love to hear it. I think it might be an issue with the actual microphone not being compatible with jasper.
