EspHome - INMP441 microphone for voice control - pipeline error

Configuration Voice Assistant

Hi,
I’m trying to configure INMP441 microphone with EspHome. I’m using ESP32 Devkit v1 with this configuration:

I have installed Whisper and Wyoming Protocol with this config and log:

When I press button for voice record I get in EspHome this, but the pipeline is not connected:

System version:

Home Assistant 2023.6.1
Supervisor 2023.06.1
Operating System 10.2
Frontend 20230608.0 - latest

I used actual stable EspHome and also tried development version with the same result.
Wiring between ESP32 and INMP441 is well, I also tried another one with ESP32-S3, but it has the same result.

Home Assistant is not using ssl secure for https, but I thought that this is only necessary for use microphone with Web Browser and isn’t necessary with HA and EspHome.

Assist is working if I write text in HA.

Do you have any idea where can be mistake?

Thank you for any point.

Have you enabled to expose to Assist in the Wyoming whisper entity?

Hi AnaCoda,

Thank you for answer. I didn’t have it allowed, so i try, but with the same result. Also tried latest esphome update version 2023.10.1 and disabled tts. I will wait for some time and then try again. :slight_smile:

I’ve got it working on an esp32_devkitc_v4
First it didn’t work with the esphome project m5stack.
I adopted the firmware that came from the web installer and did a few overrides:

substitutions:
  name: m5stack-atom-echo-d3187c
  friendly_name: M5Stack Atom Echo d3187c
  led_brightness: 10%
packages:
  m5stack.atom-echo-voice-assistant: github://esphome/firmware/voice-assistant/m5stack-atom-echo.yaml@main

# changes start here, above everything is original

i2s_audio:
  i2s_lrclk_pin: GPIO33
  i2s_bclk_pin: GPIO18

microphone:
  - id: !extend echo_microphone
    pdm: false

light:
  - id: !extend led
    chipset: ws2812

binary_sensor:
  - id: !extend echo_button
    pin:
      number: GPIO14

The binary sensor doesn’t matter… the culprit for me was pin 19 for i2s_bclk_pin which i changed to pin 18 and probably the pdm boolean which i changed to false.

According to this pinout: ESP32 DevKitC v4 high resolution pinout and specs – Renzo Mischianti
pin 18 is the SCK pin on this particular board… not an expert though but it works at leat :wink:

Next i have to add and test the dac and speaker to get the same thing running like stated on the Chapter 4 blog post. Both are waiting in my mailbox.

Hope this helps :slight_smile:

Edit:

I have to add that the reception does not work as great as demoed in the videos. Maybe it’s worth waiting for “official” firmware and schematics.

Today I finally got a setup to work reliably I followed Lewis’ guide.

Removing the button and LED from my original setup and using the pins suggested in the video. My speaker is still a bit crackly but it is working as well as my echo atom.

I had problems with the button. It switched constantly on and off so i activated the internal pulldown to stop the gpio from floating.

@Arh which microphone are you using? Do you have good speech recognition from a distance? I use INMP441 and… well impressing enough but not usable. It does not work reliably from a meter distance. If you use the ICS-43434, where did you buy it?

1 of the 2 I am playing with uses an INMP441 the other an SPH0645. Both work well after removing this line

auto_gain: 31dBFS

adding the entry into your config to enable saving the recordings to disk will help you understand what the recordings re like

assist_pipeline:
  debug_recording_dir: /share/assist_pipeline

Its still early days with mine as I have only been playing around for an hour or 2 so far.

Great, i changed it to the default (0dBFS) and it works way better now. Thanks

I can read the logs of the docker container i run whiser in. I installed it to my homegrown NAS which has way more CPU Power than my HA machine.

Commercial:
Please upvote feature request Assist: "Triggered by" for sentences for having an even better experience :wink:

If you guys also experience crackling speech output with a MAX98357 amp you can try to mess around with the gain settings.

  • 15dB if a 100K resistor is connected between GAIN and GND
  • 12dB if GAIN is connected directly to GND
  • 9dB if GAIN is not connected to anything (this is the default)
  • 6dB if GAIN is connected directly to Vin
  • 3dB if a 100K resistor is connected between GAIN and Vin

My speaker works well with the 6dB setting.

Whoa, it’s great, finally I used config from this guy and it is working. Used classic ESP32. I didn’t try it with ESP32 S3, maybe later. :slight_smile: Also it works with Wake word. Just need to do something with a few second delay between voice command and realise, but I will need to add more CPU power to virtual PC.

Secondly it will me teach to correctly speak in English like I’m not native speaker and I don’t want use native language because I thought that it will working worse than English.

Great work, thank you. :slight_smile:

Guys, I’m losing my Mind…
I’ve messed around with this for 2 days straight now, but i can’t get anything to work. When i connect the Amp, my ESP does not boot anymore, doesn’t matter if i connect it to 3v3 or 5v. Can’t get any logs out of it as soon as it is connected. If i only connect the Mic, it boots, but I don’t think i was able to trigger a wake word (looked at the ESP Logs aswell as the Binary Sensor “Assist in Use”. I Tried two brand new Amp Boards (These), Two Mics (These), and even tried a new ESP (Here) I also tried switching the Pins around from those used in the Video (13, 25, 26, 27) to those used in the initial post (18, 22, 23, 33), but it’s always the same. Am I doing anything wrong? Are my Amps broken?

Hello everyone!

I have what I believe is a pebkac error, but I’ve been working on this off and on for weeks and finally decided to ask for help from people smarter then I.

The problem - No sound from INMP441 using ESP23-S3-devkit-C-1. I have used 3 different mics and 2 boards. I have tried several different ESPHome configs (I’ll post the two main ones) and an Arduino config meant to stream the mic (will also post). I’ve also tried different pins on the ESP, and I’ve used the debug_recording_dir but the recordings all have no sound. What I’m hoping for is some way to troubleshoot why I’m not getting any sound from this mic, I’m just past my current knowledge levels and feel a bit lost.

Thank you for reading and any advice, I rely on these forums for almost everything I do. Though usually someone already asked the question I have!

do you have the LR pin on the mic connected to gnd or vcc ?

I have it connected to ground.

Rich37804

You found my pebkac error! I knew it had to use left, I thought I had it on left, but I clearly had it on right. Changed it to left and it is working! I have tweaking to do to get the light working the way I want (your example config is great!) and my speaker currently doesn’t sound very good. Once I have everything working up to par I’ll post my final config to provide one more working example. I don’t have as much time as I’d like so it might take a bit.

Thank you all again!

I have activate the logging for Assistant in configuration.yaml

assist_pipeline:
  debug_recording_dir: /config/stt/assist_pipeline

But the file always ends up 0.0KiB

When i use the Browser/app and use voice assistant there this does not happen!
So i assume the mic just doesn’t work.

I tried different things, i even have a Lolin D32 Board here which has a normal ESP32 chip. didn’t get that to work either.

I see people using esp_adf from pull #5230 but that’s S3 only right?

I don’t have speakers as i want to use my media player for that, so i only need the microphone.

L/R is linked to Ground.

BTW the mic itself is working, as tested with arduino IDE.

this can be caused by many things, if the mic is working in arduino, then everything hardware related will be working, and your yaml is correct for the mic i2s setup so no problem there.
first thing to check is that HA can stream to the device and the device can stream to HA. Check the HA Core log to see if there are any indications in there as to what the issue is Settings>>system>>logs . If the esp and HA are on different VLAN’s then have them both on the same VLAN. In order to stream audio HA needs to have all UDP Ports open, so check that any firewall is not blocking access through ALL udp ports. If running HA in docker, HA has to have it’s own IP address and network needs to be configured to host. Check those things out and let us know how you get on.
