I wouldn’t tinker too much. Apparently going forward ESP-ADF is no longer needed now that these new boards are coming out with XMOS chips for voice/echo cancelation. The firmware/software for ESP32 via I2S is apparently very new and changing. I have a Seeed respeaker kit, don’t get it, wait until Nabu comes out with something. The listen light didn’t work, Seeed actually released a firmware update that fixed it but got access denied when downloading from their wiki so someone put it on GitHub. YAML code is, well, different in some areas and similar in others. All Nabu has announced is it will have a supposedly better XMOS chip and 3.5mm input and output for another mic but don’t quote me on that. You know Nabu Casa will use it as their main voice testing device and do more updates then say, Seeed and others. I imagine trying to perfect the YAML now is pretty pointless considering a lot might change in the next six months+
I still use Nabu Cloud because it’s better than local and I’m running HA full OS on a 3 year old NUC. They did work with Nvidia to port everything to GPU based but I’m not buying a Jetson module just for local voice commands. I get why they did it, it’s kinda like a raspberry pi, just 10x the price, more for what’s recommended as the 8GB model has a RAM issues in it doesn’t have enough… An LLM is neat but not needed by me personally. I’m not a developer but obvious changes are in the yaml I use for the respeaker lite vs the Korvo-1 or S3 Box which uses a newer wake word also that does actually work better and can be used on anything using Microwakeword.
