#micro wake word detected, but does not process voice command.

For the most part the voice pe is working great, but more often than I like it seems to stop listening.
I decided to connect the voice pe to my computer and connect the serial port. When the issue happens I see "Wake word model predicts 'Hey Mycroft', but VAD model doesn't".

Following is from the console:

[D][speaker_media_player.pipeline:114]: Reading FLAC file type
[D][media_player:074]: 'Media Player' - Setting
[D][media_player:081]:   Media URL: http://192.168.15.199:8123/api/esphome/ffmpeg_proxy/27928b9c36a1afbca840cc6e65c2a2f8/gie4Sf9r7F4LOw95Fw9RDg.flac

[D][micro_wake_word:352]: Wake word model predicts 'Hey Mycroft', but VAD model doesn't.
[D][micro_wake_word:352]: Wake word model predicts 'Hey Mycroft', but VAD model doesn't.```

The announcement played and then several minutes later I tried to issue a command and got the VAD model doesn't message.

Tried some searches and did not find any hits?

micro wake word detected, but does not process voice command.

#

Yes I have been trying all 3 stock words with no luck. It seems to have gotten worse with the last update, which is why I opened a terminal window to see if I could get a bit more info other than "it doesn't work"

#

After I power cycle the voice pe works fine for awhile and then just stops. I haven't figured out the sequence of events that gets into the above state.

#

so the VAD is "A Voice Activity Detection model to reduce false accepts from non-speech sounds." how exactly that works is a bit beyond me but is there background noise potentially thats messing with it?

#

next time it happens instead of power cycling try using the physical mute switch to mute for a few seconds then unmute.

Not really.
To me it looks like the voice pe is "kind of hung". I say the wakeword it beeps but never listens (based on looking at the leds). After that the voice pe also doesn't play and "cloud say" announcements anymore until I power cycle it.

#

I have also tried the mute switch, and pressing the center button as well, with no joy.

thats super odd, have you tried a clean flash of the firmware?

No.
So far I have run the stock firmware.
Updated by home assistant.
I have not adopted the voice pe into ESPhome

#

it may not help but it couldnt hurt to try that one

#

you may just have a faulty unit

Maybe, going to run it with the console connected for a bit to see if I can get some additional data. If no joy then I will give a reinstall of the firmware a try.

Looking at the console output when things are working I see

[D][voice_assistant:676]: Event Type: 11
[D][voice_assistant:844]: Starting STT by VAD

When it didn't work it just had the events from mww:352 so they could be from normal processing. What didn't happen is the event type 11.

Will wait for a reoccurance to see if I can see what sequence (if any) leads into this issue.
