Problems with speech recognition

Blane

Hello bugsounet, first of all many thanks for your great work. Do you have any idea where the problem could be? The google assistant does not respond to any voice input. In the terminal output of gateway there is a warning from arecord(screenshot1) every second. As I understand it does not find the micro. So I started looking for the device name in your files and found the following entry in three files:

/MagicMirror/modules/EXT-Detector/components/porcupine.js
./MagicMirror/modules/EXT-Detector/node_modules/@bugsounet/snowboy/index.js:
./MagicMirror/modules/EXT-Detector/node_modules/@bugsounet/snowboy/sample.js:

device=“plughw:1”

When I tried to start a recording with arecord --device =plughw:1 --format… I tried to start a recording and got an error. So I searched for my device name, it is “plughw:2,0”. At least I can start a recording with arecord --device =plughw:2,0 --format…(screenshot2) and record sound. After I have adjusted the entries in the three files (screenshot3), unfortunately the message still appears and the voice input still does not work. Maybe you have an idea what else it could be?

Hi,

there is no micConfig to do
why ?

since last version of buster and now bulleyes, RPI os (like all linux debian compliant) use a program named pulseaudio
this program is able to::

determinate what recorder is plugged (with device name)
record and use all recorder at the same time without comflit of take hand

the device name is default

You can discover it with arecord -L command

default
    Playback/recording through the PulseAudio sound server

After if you modify .asoundrc file , you break the configuration and it can’t works
If you remove /disable or uninstall pulse audio server, it will not works too

Finaly, I force this configuration (and you can’t change it)
mic: { recorder: 'auto', device: 'default' }

I had no intention of changing the micro configuration. The voice input did not work and then I came across the warning in the gateway terminal output. I just wonder why the voice input does not work. I have installed and configured everything according to your instructions. When I make a request to google via the gateway tools, it is answered and displayed on the mirror.

first thing to verify is this:

Gateway v3.0.1 (230316.fr) 

pi@raspberrypi:~/MagicMirror $ ps aux | grep pulse
pi         686  0.2  0.4 648580  8612 ?        S<sl Mar15   3:49 /usr/bin/pulseaudio --daemonize=no --log-target=journal

and this:

pi@raspberrypi:~ $ arecord -L               
null
    Discard all samples (playback) or generate zero samples (capture)

....

and OS version:

pi@raspberrypi:~ $ uname -a

and verify if:

.soundrc is NOT created

pi@raspberrypi:~ $ cd ~
pi@raspberrypi:~ $ cat .soundrc
cat: .soundrc: No such file or directory

Here are the outputs

bugsounet

ok perfect !

Can you retry with this:

pi@raspberrypi:~ $ cd ~ && cat .asoundrc 
cat: .asoundrc: No such file or directory

sorry

bugsounet

After, I think to this:

Maybe you use another process or module in MagicMirror that uses your microphone with old protocol.
In this case, your micro phone will be not available

You can try this:

turn off MagicMirror app
open a terminal and try this:

arecord -D default -q -r 16000 -c 1 -t wav -f S16_LE -d 3 test.wav && aplay test.wav

it will use pulse audio for opening the mic, record 3 seconds and play test.wav file

tell me if any error ?

If error can give me the result of this:

pi@raspberrypi:~ $ ps aux | grep record

Thank you very much for your support, unfortunately I can’t work on the mirror again until Monday. I will try and post the outputs on Monday

Hello bugsounet, tried what you wrote, the file .asoundrc does not exist and the recording started and played back without error.

cd ~ && cat .asoundrc 
cat: .asoundrc: No such file or directory

admin@raspberrypi:~ $ arecord -D default -q -r 16000 -c 1 -t wav -f S16_LE -d 3 test.wav && aplay test.wav

bugsounet

Hi,

For me it’s good.

So, Can you try to disable all modules in your config except:

MMM-GoogleAssistant
EXT-Detector
Gateway
EXT-Alert

and retry ?

Hello bugsounet, unfortunately, nothing has changed. The file is still not present and the recording worked and was played back. After deactivating the modules, the MagicMirror just stays black and I can no longer reach the gateway

admin@raspberrypi:~ $ cd ~ && cat .asoundrc 
cat: .asoundrc: No such file or directory

admin@raspberrypi:~ $ arecord -D default -q -r 16000 -c 1 -t wav -f S16_LE -d 3 test.wav && aplay test.wav
