ESP32 "No wake word detected" filling up logs

ESPHome
1

I recently received an ESP32 Lyrat board but I’m pulling out my hair trying to get it to work with openwakeword in ESPHome.

The minute the device boots, the logs are filled with this section repeated multiple times. Any idea what’s going on? It looks like no wake word is being detected so it ends the pipeline before I can say anything to trigger the wake word.

Hi there,

I followed your blog post for the device, and having the same results as mentioned. The logs are spammed with ‘No Wake Word’ detected and I cant seem to get any audio out of it when I do a TTS event.

Its the Lyra 4.3 board (confirmed it looks like yours)
Any hints?

Is the wake word switch on?
If so, can you turn it off then back on?
What microphone are you using? Its not running.

Its this board… ES8288 codec

https://espressif-docs.readthedocs-hosted.com/projects/esp-adf/en/latest/design-guide/dev-boards/get-started-esp32-lyrat.html

Reset it … and after a few minutes of spamming, it settles down to something else in the logs

I never found the root cause of this issue but as @RichardPar said, the simplest workaround is to turn off the use_wake_word switch, wait a second and then turn it back on.

For those who haven’t seen my project, here is the article which includes the esphome yaml config.

Thanks!

I changed the yaml a bit to reset the component… do you know of a method to record the audio on the HomeAssistant side? or a way to verify that audio is getting though?

Much appreciated
Richard
