Voice Reactive/Voice Responding Feature?

I wish we had some type of voice responding feature using AI or something that could recognize certain words. Say like if we could input a voice recording of someone saying “hello!” And then the effect could identify when the user said something that sounds like that/very similar.

I think this would be really cool since we could utilize it for a ton of different effects, maybe even teach others different languages with it. I feel that more audio-reactive features like this would be a really great addition!
