Microphone Error
Platform (Hardware/OS):
Raspberry Pi 3 Model B Rev 1.2
Raspbian Stretch
Linux raspberrypi 5.4.51-v7+ #1333 SMP Mon Aug 10 16:45:19 BST 2020 armv7l GNU/Linux

Node version:
v10.23.3

MagicMirror version:
MagicMirror: v2.14.0

Module version:
1.0.2

Description of the issue:
After Installing a fresh Raspberry Pi with a fresh Magic Mirror and all the dependencies for this module, I cannot get it to work.
I configured only these modules:
alert, clock, MMM-voice
After starting the Magic Mirror and opening the URL, it only shows "ERROR" in the lower section. Find my config attached
config.js.txt
(I renamed the config to config.js.txt as I couldn't upload it as config.js)

My Audio Hardware
I'm using the "ReSpeaker 2-Mics Pi HAT" Module for Microphone. I installed everything from https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/ and I can successfully hear myself, when I try "arecord -f cd -Dhw:2 | aplay -Dhw:2"
The config also contains "microphone: 2".

I wasn't able to debug some information (because the Chrome Developer Tools didn't gave me any hint and I have no idea how to enable debugging for "npm run start" or "npm run server"

Any idea, what's going wrong here?

@spencerandhill thank you for the detailed description. On a first glance the config seems right. To get more details you can run the module as:

{
  module: 'MMM-voice',
  position: 'bottom_bar',
  config: {
    debug: true,
    microphone: 2,
    keyword: 'MAGIC MIRROR',
    timeout: 15
  }
}

This will generate a debug and error log in the module directory with more informations.

@fewieden thanks for your fast response! I got the log and also some hints.

Error opening audio device plughw:2 for capture: Device or resource busy
FATAL: "continuous.c", line 245: Failed to open audio device

And later:

INFO: continuous.c(275): Ready....
INFO: continuous.c(261): Listening...

Unfortunately I have no idea, why it can't access the audio device.

The full debug.log is attached here
debug.log
and the error.log here
error.log
(Error Log only shows a couple of lines with the number "127", nothing else)

commented

@spencerandhill resource busy usually was reported when a user had something else running that accessed the microphone.

You could try to run pocketsphinx standalone first without the mirror.

pocketsphinx_continuous -adcdev plughw:2 -inmic yes -lm PATH_TO_LM_FILE -dict PATH_TO_DIC_FILE

This is how the module is running it.

Hi @fewieden , I have a similar issue, it says
ERROR undefined

Platform (Hardware/OS): RPI 4B 2GB

My config
{ module: 'MMM-voice', position: 'bottom_bar', config: { debug: true, microphone: 2, keyword: 'MAGIC MIRROR', timeout: 15 } }

error.log shows
127

debug.log shows
pocketsphinx_continuous: error while loading shared libraries: libpocketsphinx.so.3: cannot open shared object file: No such file or directory
I checked the file is there in /usr/local/lib
I also tried writing this in .bashrc but no luck
export LD_LIBRARY_PATH=/usr/local/lib export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Appreciate any help with this!

Hi @fewieden , I have the same problem.
I have run the debug log and in the error.log is one Error several times:

The command: pocketsphinx_continous is not found

from debug.log I copied this ERROR:
ERROR: "dict.c", line 275: Failed to open dictionary file 'MMM-voice.dic' for reading: No such file or directory

I'm sure this file is existent.

commented

@maku1958 this sounds like something went wrong with the installation and he can't find the binary file.

I suggest deleting the module directory and starting from scratch.

With your debug.log file, this could be an older message. If you are sure the file exists it is usually a good idea to delete the log files again before the restart so you only see the still relevant entries.
