Gate Audio Signal Using VAD
This model uses if-else block signal routing to replace regions of no speech with zeros.
To explore this model, tune the Probability of transition from a silence frame to a speech frame and Probability of transition from a speech frame to a silence frame parameters of the Voice Activity Detector (VAD) and observe the effect on the speech presence probability. Toggle between the gated and original audio signal to assess the quality of your system.
