Can't set a hotword with deepspeech

I tried to set my hotword for deepspeech on my raspberry pi and got a really long error when I sent this in terminal:

python3 /home/pi/DeepSpeech_RaspberryPi4_Hotword/mic_streaming.py --keywords jarvis

Error The error. I tried to post it in text but it kept saying the code isn't formatted correctly. I don't know if an error counts as code so i'm just sending a screenshot.

I don't know how to fix this and didn't find anything anywhere else.

Solution

  • these errors are not related to DeepSpeech, they're related to ALSA, which is the sound subsystem for Linux. By the looks of the error, your system is having trouble accessing the microphone.

    I would recommend running several ALSA tests, such as;

    arecord -l

    This should give you a list of recording devices that are detected, such as:

    $ arecord -l


**** List of CAPTURE Hardware Devices ****
card 2: Generic_1 [HD-Audio Generic], device 0: ALC294 Analog [ALC294 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

    If this is not what you expected, you can use the command alsamixer to select another sound card and/or microphone.
