Hi all,
I found this board on Mr.ali express.
Can it be used for wakeword and voice assistant setup.? It looks cool.

This is probably a better link to understanding the board.

And if you want it, then I recommend you to buy it from the Espressif Official Store instead, so you know the quality is okay, the version is the latest and the last fixes have been applied to the design.
According to the link I posted above there are maybe 5 versions for sale, if not more.
Version 5.0 seems to be the newest one.

If you build it, a write-up would be appreciated.
Everything Smart Home recently made a video about setting up a wakeword using an ESP board. Not the same one you linked to, but some of his steps might help you.
The board is not the problem here.
It is the audio parts that might need a special configuration and setup.
Thanks for the link. Yeah I agree make sense to buy from them directly.
Thank you. I did watch the video. And I actually bought the items in the video to try it out. But it made me wonder if there were more options to try. The price is also pretty steep on this product. Basically I can make two devices for the price of one of these boards. But just thought if the microphone was better and this could fit in a nice box then it would be a good start. But maybe I should just try it out if no one else have some experience with it. 
Of course.
I do not think the board is worth the extra money it cost.
It is not that the board is not good, but rather that there is a lot of extra features on the audio part that will never come in use with ESPHome.
The board have a built-in led ring that might be able to be used with ESPHome, but it also have 3 digitale and 3 analog microphones, which means it record 6 channels at the same time and these can then be used to combine into/choose the best source and do direction of activation determination.
It also have chips to help with echo cancellation, dereverberation and beamforming, which is all good tevhnologies, but probably not supported by ESPHome.
I think you are right here. I have also spend some time reading more about the board. It does sound like a nice board and great capabilities for voice / ai but properly not flashed with esphome for assist purpose in mind. I was looking for something that can replace all my Alexa stuff and maybe in a nice package. Will tamper with the ESP32, mic, amp and speaker I bought and see if that will be sufficient of a setup to begin with and build into something.
There’s a full discussion of that board with voice assistant here. Including YAML configuration.
It’s basically running, but everyone is welcome to contribute.
It looks like it is just one microphone that is used on the board in that ESPHome setup and none of the other features.
The board might work, but it is not at all using the boards capabilities to the fullest, and I still think it is too expensive compared to other boards.
Found someone who got it to work, nice!
