Is it possible to use only arduino to do voice recognition? or maybe with esp32 no internet.
I found speech recognition chip but that's not what i want I got esp32 esp8266 and arduino board. I would like to know if somebody could do it
No. It's as simple as that. No. Voice Recognition is a very very complex task. To do it fast and well in a "general" way takes a neural network, or a very powerful PC (note: all common ones now use online resources to do all the work).
A voice recognition chip generally is pre-programmed to respond to specific words.
