VAD segment length cap at around 20s #1136
Comments
It is not the default behavior of silero vad. We add such a constraint since many users complain that the vad gives them a very long segment. Typically, you won't get a segment more than 20 seconds if there are longer pauses in your audio.

Hi, was playing around with the VAD model and realized that the maximum speech duration is kept to around 20s regardless of the buffer size. Took a look at the code and saw that it is hardcoded in this line:
https://github.com/k2-fsa/sherpa-onnx/blob/de04b3b9bfc6d48a8ac340e00083d9fd5411b81e/sherpa-onnx/csrc/voice-activity-detector.cc#L156C7-L156C29
Would be nice if this can be a parameter that can be modified. My instinct is that the buffer sort of control the maximum duration, but that turns out to be wrong. Not sure if this is the default behaviour for the original silero vad as well.
