A presentable voice assistant satellite

hello everyone. Does anyone knows is this product (the speaker) can be found somewhere in EU?

Just go to any cheap corp-o store or 2nd hand store and grab any low-cost speaker. Dump the guts out and slam in a esphome esp32-S3 with the INMP441 Mic / Max98357 DAC and you’re done.

I wish it could be so easy. But I have no (almost) solding skill and also lack of spare time (and a wife who wants only nice solutions :slight_smile: )

Then buy an ESP32-S3-Box-3 when mouser releases them https://www.mouser.com/ProductDetail/Espressif-Systems/ESP32-S3-BOX-3?qs=sGAEpiMZZMuqBwn8WqcFUipNgoezRlc4u4gjCc9cblNcfZiByE2ecw%3D%3D

yes but I want also to use them to stream music (so the speaker have to be “solid”)

There were some discussions in this thread as to whether or not a bluetooth speaker with built-in mic could be used directly as a satellite (without esp etc.). Did anything ever come of that or is there a thread for this approach?

I love the creativity of this and some of the other projects here :clap: but ultimately I would also be interested in just using out of the box bluetooth devices by simply pairing them to the HA server or an esp32 acting solely as a bluetooth to wifi relay.

Just attach the bluetooth mic/speaker device to RPi bluetooth

And that will work as a satellite that reacts to wake words?

I dont think anyone has gotten that to work yet.

Been googling this but can’t see to find how to do it. Any pointer?

It just acts like a plain microphone / speaker for the system whatever you have on that system should be able to use it as such.

Here is my esphome config for the esspressif esp32s3 korvo-1 development board. I ended up getting it since an S3 Box is impossible to get. It works, all the LED’s work as they should but it could probably use some tweaking to take full advantage of the hardware. Now I just need to design a 3D case. Best part is it has speaker outputs for low power or powered speakers and a 3.5mm output for pretty much anything you want to hook it into for sound output. No onboard speaker though.

For anyone looking for an elegant, 3d printed (that is covered with a textile speaker grille) enclosure for the Korvo and Korvo1, have a look at my WIP over here Far field satellite with an Elegant 3d printed enclosures

I’ve been following this thread, but it would be great if someone could wrap it up, with some simple to follow instructions on the board in regards to how it all finalized with what works best. both for the S3 dev board and the regular esp board.

Hello, with my ESP32 N16R8 I was able to control the RGB LED, use the wake word, the actions are well done but despite all my attempts I did not manage to output sound via the Max98357 either in speaker mode or media_player. So also a taker of a connection / code that works with the ESP32 S3 :wink:

Here is a link to the code I use on N16R8. It works, but has a few false positives when the radio is on in the background. So need to do some fiddling about with settings.

Thanks to BigBobbas

As an update to my crackling speaker issues, I replaced the max98357 and it was fine. So one non working amp.

hi

i seen your post, i tried the same setup with my esp32 wroom32 but have issues with the media_player, when i play a file the esp32 crashes.

is the ESP32-s3-N16R8 Dev Board better than the “ESP32 wroom 32” ?

how do you make it which the command to stop the music?
i read something about custom commands with the assist, or is it possible to mute the sound when the wake word is speaken?`

Everyone with noise problems… it is the 3.3V or 5V supply voltage… I run an OrangePI 2W with USB Audio and it was noisy. The solution is to Boost 5V to 8V and use an analog Voltage regulator such as 7805. I cut the red and black cables in an USB extention cable being careful of the data wires, and connected the MT3608 Boost converter and the regulator 7805 supplying smooth voltage to the USB audio module. Be aware if you need 3.3V you need a 3.3V regulator and no Boost converter if you have 5V somewhere. For me the noise disapeared completely /Mikael

Well, I was wrong, i thought the repository was handling microwakeword and it wasn’t, here is the updated working esphome code for microwakeword. Also, if you flashed it with the board as esp32-se-devkitc-1, it only formats as either 4MB or 8MB, I was pulling my hair out until I realized the PSRAM was more then double the ROM showing in esphome. It said the BIN file was 19xxx bytes and the flash was 18xxx bytes so I automatically assumed 18MB when it’s nowhere close to that… Just had to specify the flash size, one line…

Remeber to change API key, and wifi as I have it statically IP’d. Also, it points to a non existent file for the firmware, because of this, it shows up as red in esphome but everything works and you will always be prompted to install a “new” device. Just leave it alone, don’t adopt it. From what I understand, it will need to be added on the esphome side and there has been a feature request to add it. If that will happen or when, if ever, I have no idea. If you comment it out, it fails to flash… Everything works without issues although I’m pretty postie the buttons don’t do anything. There are some warning during install and they are way above my skill set as I am not a developer but can cut and paste other peoples code and mess around with it and usually can get things to work. Most credit goes out to whoever wrote the repository I am pointing to because I never would have been able to do it without that

Many people have already written about the fact that crackling and noise are primarily caused by interference in the wiring between the ESP and the sound module board. Because it is not just a relay or LED control wire, but a digital serial data bus operating at high frequencies. The best solution is to use no wires at all. I’m sure everyone has these things, they are usually bundled with the boards. I made such an assembly, I’m sharing the pictures. No noise when turned on, in operation, crystal clear sound in music and voice.




In my opinion, this is more reliable and compact.
The sound module board (amplifier) should be powered directly from 5 volts, the microphone board from 3.3 volts. I took out a separate type-c power connector and soldered it to the esp directly to the inputs of the 3.3 volt step-down converter (don’t mess it up). This gives the least amount of voltage dropout.

And yes, I confirm that microphones can be easily killed when soldering. In my case, flux got into the hole and I couldn’t get it out with alcohol and other cleaners.

p.s.: And another mounting option (this is not for a speaker, but as an adapter to a 5.1 system)
