Why I cannot use function for input voice from callback #439

Open ploveaiit opened 6 years ago

ploveaiit commented 6 years ago

run snowboy and detected hotword then call my function

and then I got this error "IOError: [Errno -9985] Device unavailable"

code in my callback function import speech_recognition as sr r = sr.Recognizer() with sr.Microphone() as source: audio = r.listen(source)

thank you for your help

The error says your function was not able to get the microphone. Most likely the microphone is occupied by one thread (e.g., snowboy) and you are trying to use it in another (e.g., your recognizer)

What should I do to fix this problem ?

Are you using Raspbian?

ploveaiit commented 6 years ago

Yes I am using Raspbian Debian 9

Go to start. In preferences select audio device. Then select sound card. Select all the options one by one. If you find Microphone and auto gain control in one of them, then that is your microphone. Select both the options. In the capture tab, set your microphone volume to full, and In switches, enable auto gain control.
