UnverifiedTraditional VAD methods rely on acoustic features like short-time energy and zero-crossing rate, while modern approaches use deep neural network models such as WebRTC VAD and Silero VAD.73% similarUnverifiedSilence detection is typically based on the RMS (Root Mean Square) energy value of an audio signal; when the RMS of an audio segment is below a preset threshold and its duration exceeds the minimum silence length, that segment is marked as a silence candidate.69% similar
