Unverified50% confidenceFactExact time
In the case study, using mfa segment for VAD segmentation produced worse results than no segmentation, because automatic VAD may make erroneous judgments in scenarios with severe crosstalk.

UnverifiedFiltering audio down to segments of a single speaker breaks pause-detection logic in a non-intuitive way, as the removal of silence segments may prevent the VAD model from correctly identifying pause boundaries.75% similarUnverified端点检测（VAD）本质上是二分类问题，用于区分有效语音帧与静音/噪声帧，现代神经网络VAD如Silero VAD可在嘈杂环境下精准区分停顿与结束71% similarUnverifiedEnabling VAD (Voice Activity Detection) preprocessing to first remove silent segments before feeding audio into the model can significantly reduce hallucination.70% similarUnverified现代神经网络VAD（如Silero VAD）通过训练大量语音数据，比传统基于能量阈值和过零率的VAD更精准区分停顿与结束64% similar
