Yes - please chase up the WVR ESP32 dev board. Sounds exciting

[Tarbard]

Hope you are feeling better soon, thanks for the episode.

Anything pi pico audio related gets my interest

[mathom]

Lots of cool audio things. Get well soon!

[StefanSchlott]

Hope you get well soon! That ESP-audio-thingy sounds really interesting, let's hope there will be a decently-prized way to get one of those...

[GaryFuller]

Hope you feel better soon Ian! Shame that Alexa development board is more US focused. I have far too many Echo devices in my home.

[miked]

I am really interested in what you find out about getting the WVR modern, open-source embedded audio ESP32. Interested in one or two myself!

[albygnigni]

Do you know when cm4 will be back in stock?

[pulkitjoshi]

Hoping ACK can be used for commercial products😅not sure how these liscence works

[Mudhenn]

Hi, I really like to know if you find a way to buy the esp32-Audio-Chip. So please talk about it in your show if it happens. I also hope you get well soon!

[shreyaskul]

Hmm, the ESP32 alexa integration looks interesting, I hope to see if similar thing can be done with Google Assistant...
