A parrot would repeat what you said

The Parrot is a parrot, it can repeat what you said, actually, it can detect your voice and then record it, and play it, that is all. I use this to improve my English speaking, you know, I can hear what I said and then I can correct myself.

First, denoise the audio input while recording. Put those data into a VAD SDK, find those active areas, then save it, and play the sound for users.
