Sound Recognition

Hello! I want to know if there is some library to recognize specific sounds. That is, some parts of the code will be triggered only when a certain sound is recognized.

So far I tried to isolate only low sounds from voice (actually that would be enough) with the sound library and FTT but it seems voice (at least through my mic) has very even levels in all the frequencies.

Or maybe if I use p5js there is a library?
