# video_audio_ASR_mapper

Perform automatic speech recognition (ASR) on video audio streams using the SenseVoiceSmall model. This operator extracts audio from videos and transcribes speech content. It must be operated after video_tagging_from_audio_mapper, as it only processes videos tagged as containing speech.

使用 SenseVoiceSmall 模型对视频音频流进行自动语音识别（ASR）。此算子从视频中提取音频并转录语音内容。它必须在 video_tagging_from_audio_mapper 之后运行，因为仅处理被标记为包含语音的视频。
