I have a question, if I want to recognize voice frequency, for example “Police car”,“Ambulance”, “Fire engine” by arduino uno, how can I do that?
If I only have mini microphone, can I use microphone to recognize?
I find some way might to recognize voice, that is speech module, but I am not sure whether that is useful.
And also these speech recognition module are other company product, how can I create that by my self?
Who can give me some tips?
