MMM-voice
-
I wrote this in a different thread not too long ago actually, but I noticed a vast increase in detection/response rate when moving from a cheap USB mic to a decent webcam microphone. I would say the response now is on the order of 1-2 secs, with effectively no errors in voice interpretation. I’m sure this is helped immensely because the clarity of the audio into the rpi is much clearer - the cheap USB mic had terribly noisy audio in.

i am running MMM-voice on an ODroid Xu4, which is very fast.
I also use another voice enabled smart mirror on this same device.
with a Logitech webcam as the mic.
MMM-voice gets the hotword correct every time, but almost none of the following words.
the same hardware setup works correctly with arecord as the wav source, but uses google speech detection for everything after the hotword.
it appears the system is using the default language model (lm) and dictation (dic) files.
anyone have a suggestion on debugging this?

@sdetweil set
debug: truein the config and you will see what the mirror recognizes -
i have that, but the text ‘recognized’ is not what i said.
if I speak slowly, i can get ‘magic mirror’
then wake up is ‘wake go’ or ‘wake all’,hide calendar is ‘hide who’
open help is ‘open go’the smart-mirror project also uses ‘go to sleep’ and ‘wakeup’
‘hide newsfeed’ is ‘hide to show the’, ‘hide is the’
none of the commands, when recognized, do anything…
hide modules
go to sleep (not on PI so the tvservice doesn’t exist), but no error is logged

@sdetweil I can tell you the same as I just told another user
as the author of MMM-voice I can tell you, that my module doesn’t support a command called hide clock at all. You are probably using hello-lucy, at least that’s a mod I’m aware of which enhances the commands. You can see the command list here https://github.com/fewieden/MMM-voice#usage
i also had problems due to my accent. you can also look into the dic file how the system expects you to pronounce it

ok, got it… voice detection is sensitive…

@strawberry-3-141 OK i am trying to install this module and i have read all forum posts on this thread.
I did have AlexaPi installed and working previously and as i can tell from other users this installation ruins it but i could live with that. However MMM-voice keeps giving error 1 on its error log even after deleting node modules, pocketsphinx and sphinxbase and reinstalling again. The icon on MM goes briefly Ready Select Mode than back to Error how do i fix that like i said i have read everything all installations go perfectly all 1 through 5 out of 5. what am i doing wrong??
The other question is… I also want to use 2 microphones ideally and both apps… i was using AlexaPi flawlessly with one of the mics and i wanted to use a second mic for MMM-voice since it gives you the option to select which one you want to use do you think that is doable? is it meant for that??
What can i do to use both AlexaPi and one of the MMM voice modules so i can control the display and show and hide certain modules both on the same Rpi.
I tried MMM-MirrorMirrorOnTheWall already but i am stuck half way with no one to help me through the end and it is an extremely difficult module to fully install.
Anyhow any help will be greatly appreciated

@richland007 can you please enable temporarily the more detailed debug log with
debug: true? -
@strawberry-3-141 Thank you so much for replying back to me :)
Did what you asked and on the MM itself it says Error Undefined but on the debug log everything sems to go fine until the very last sentence that says this:“Error opening audio device plughw:1 for capture: Connection refused
FATAL: “continuous.c”, line 245: Failed to open audio device”When i run “cat /proc/asound/cards” i get this
“0 [ALSA ]: bcm2835_alsa - bcm2835 ALSA
bcm2835 ALSA
1 [Set ]: USB-Audio - USB Headphone Set
USB Headphone Set at usb-3f980000.usb-1.5, full speed”And in the config.js file obviously i have selected the only mic i have right now number 1 USB headphone set and i know it is working just fine.
Let me know how what does that tell you
and again thank you

@richland007 can you check the following to see if another program can access the mic https://scribles.net/voice-recording-on-raspberry-pi/
Is there already another Programm running in the background which is accessing the mic?
