Though I’m adding noise and distortion to my voice output, I’m sure canceling out noise can be done without much trouble. I also recommend running ‘alsamixer’ beforehand, to make sure you can see all the devices, and they’re not muted. So I decided to verify that claim myself, run some benchmarks on different hardware and make my own audio transcription application with hot word detection. Adafruit Voice Bonnet features two speakers and two mics, that can be used as an audio-voice interface for Raspberry Pi SBC to create a DIY smart speaker or other audio product. Connect one leg to the ground (GND). The Interference Canceller nulls point noise to cancel out typical noise in the soundscape, Stereo Acoustic Echo Cancellation suppresses unwanted speaker echo and enables barge-in across audio playing from the device, while noise suppression removes background noise from other devices. A subreddit for discussing the Raspberry Pi ARM computer and all things related to it. Required fields are marked *. THe sound adapter has standard 1/8th” jacks for mic in and audio out, so just plug right in (I had a small problem with my Mic connection, in that the mic cable I used needed to be ‘out’ a quarter inch to connect properly.
