<![CDATA[How to do Voice Activity Detection (VAD) Algorithms?]]>Hello!
I’ve been working on a sound installation that records your voice on a public space and then plays it back on a FM radio transmitter.

Since then, I’ve been searching for different voice activity detection (VAD) algorithms for Pure Data and found very little.
So far, my best lead is this article: https://medium.com/linagoralabs/voice-activity-detection-for-voice-user-interface-2d4bb5600ee3

So I thought I’d share my simple algorithm for VAD in public spaces and ask:

How would you approach detecting voice activity in real-time in a public space with a lot of noises and non-voice signals?

Here's my patch: VAD.pd

bonk~ to detect the sensitivity before go to sigmund?
