Esp32-s3 local voice asistant

ESPHome
1

Hello,

I want to create a voice assistant using an ESP32-S3 via ESPHome.
Unfortunately, I’m encountering some issues, no wake word seems to be detected.

I’ve used a Max98357 and an INMP441 connected to an ESP32-S3 (the pins are different from the diagram).

Here’s my ESPHome configuration.

However, when I turn on the switch, no keywords are recognized.
Do you have any ideas on how to solve my problem, please?

If i do a debug test on my smartphone the Hotword detection does work!

So i presume the microphone might be broken, or not? we will never know!

ohhhh i remember i had issues before!

configuration.yaml needs this line:

assist_pipeline:
  debug_recording_dir: /config/stt/assist_pipeline

sadly my file (20 seconds) is 0kb in size and seems broken.
If i do a pipeline test on my smartphone i get a 44kbit file and can hear myself talking.

You need to set the microphone to Left for starters.

microphone:
  platform: i2s_audio 
  id: external_microphone 
  adc_type: external 
  i2s_audio_id: i2s_in
  i2s_din_pin: GPIO4
  channel: left
  pdm: false
5

doesn’t make any difference.
Tried left, right. with L/R grounded or not.

I have 2 of these with the S3 boards running real well right now. Here is my config. You have alot missing to make these boards work for this.:

Unfortunately, it still doesn’t work. I’ve tested the microphone on the left and completed my configuration.
Just like @Haldi, I’d like to be able to test if my mic is working or not.

Same here. I think the S3 support isn’t that far in esphome. Hopefully, it will get better.

@egreh4trj896436sfz
IF you have Arduino IDE installed i found a working script for 2.0!

So i did everything right with soldering and the mic is working!

Normal value is around -30 - 30 and when you yell it goes up to 5000 !

Now i just need to strip down Rich’s yaml from everything we don’t need for a working microphone -.-

@Haldi
Have you found a working configuration to make your microphone function?
Despite copying @Rich37804 configuration, I am unable to achieve something functional.

11

Have you tried this wiring and code? Since those are from two different places you may need to adjust the GPIO pin assignments slightly (I didn’t check if they line up) but that’s the correct wiring and I have had success with that code. (I also changed the GPIO to suit the particular ESP board I have.

Thank you very much, the wake word microphone works very well, but the voice recognition doesn’t seem to work. However, Whisper works with my phone.
Would you have any ideas?

The component requires an ESP32-S3 with PSRAM to function.micro_wake_word

# for example ESP32-S3-WROOM-1-N16R8
psram:
  mode: octal
  speed: 80MHz
