Any success using the HUZZAH Feather for speech rec.?

Hi,

Has anyone had success in using the Huzzah 8266 for simple speech recognition projects, such as setting gpio pins high or low?

If so, can you share the code (hardware, etc.)?

A few hobby modules are available that recognize a limited number words or phrases, and they will work with any MCU.

Some unconvincing Youtube videos have been posted demonstrating success with the ESP32, but draw your own conclusions from the lack of progress.

For the time being, it seems that a Raspberry Pi is about the minimum that can do stand-alone speech recognition, for more than a few words or phrases. Here is a somewhat outdated review https://www.seeedstudio.com/blog/2020/0 ... respeaker/

Thank You for your response, SJ....can you name the, "hobby modules"? I not looking for an Alexa type vocab function, only something that would recognize an on or off command..... for a specific gpio pin, to turn a relay (like FeatherWing), on or off.....

I was wondering if anyone has tried a unit such as the Beaster Voice module....attached:

Here is one to try: https://www.robotshop.com/products/grov ... ion-module

I haven't used it, but have seen some positive reports, e.g. https://www.elektormagazine.com/news/gr ... uino/18310. There are other similar products, mostly from Asian vendors. You can find some helpful comments in product reviews, robotics forums, etc.

Edit: the Beaster is advertised to recognize 80 words, but only 7 words or phrases can be active at once. The figure of 7 seems to be a common limitation, suggesting that similar modules all use the same basic framework.
