Trying to implement a classic spectral subtraction algorithm using Opus voice activity detector, and have a couple questions: 1.Should there be any overlap between PCM frames input to the voice activity detector, and if so, what windowing (e.g. Hamming) should be applied to the frames before being input? 2.Is there a threshold value for either the speech activity level of a frame or the probability of speech occurrence that is typically used to assert that speech did or did not occur in the frame?
