skillsbench 是做什么的？
结合视觉特征（人脸检测、嘴唇运动分析）与音频特征，提升视频文件中说话人分割的准确性。使用OpenCV进行人脸检测和嘴唇运动追踪，然后将视觉线索与基于音频的说话人嵌入融合。当处理包含多个可见说话人的视频文件，或纯音频分割需要视觉验证时，该技能至关重要。

该技能旨在通过融合视觉和音频特征，显著提高视频文件中说话人分割（Speaker Diarization）的准确性。当处理包含多个可见说话人的视频文件，或纯音频分割需要视觉验证时，该技能至关重要。它利用OpenCV进行人脸检测和嘴唇运动追踪以提取视觉线索，然后将这些线索与基于音频的说话人嵌入（Speaker Embeddings）进行融合。通过整合视觉模态信息，该技能能够有效识别谁在何时说话，从而减少纯音频方法的误判，特别适用于视频会议、多人访谈或影视剧等场景。该技能支持CLI工具，并鼓励用户根据环境调整参数（如GPU或OpenCL优化）。
