生成 Microsoft Stream 视频的自动字幕和记录Generate automatic captions and a transcript for your Microsoft Stream videos

如果视频的语言字段设置为受支持的语言,则 Stream 可以使用自动语音识别技术自动生成字幕。If a video's Language field is set to a supported language, Stream can automatically generate captions using Automatic Speech Recognition technology.

重要

  • 自动生成的标题当前支持英语中文法语德语意大利语日语葡萄牙语西班牙语语言。English, Chinese, French, German, Italian, Japanese, Portuguese, and Spanish languages are currently supported for autogenerated captions. 注意:对于USGOV ,我们仅支持英语西班牙语NOTE: For USGOV we only support English and Spanish.

  • 仅对 "自动脚本" 仅支持 .wmvWMV文件。Only MP4 and WMV files are currently supported for automatic transcripts.

  • 你可以选择:自动生成标题或上载标题文件:You have a choice: either autogenerate captions or upload a caption file:

    • 如果已经上载了标题文件,则无法自动生成标题。You can't autogenerate captions if you have already uploaded a caption file.

    • 如果已选择 "自动生成标题文件" 选项,则不能上载题注文件。You can't upload a caption file if you have selected the Autogenerate a caption file option.

创建自动题注需要一些时间。Automatic captions take time to create. 该视频的持续时间通常为1倍,例如,对于一个小时的视频,预计大约等待两个小时才能完成处理。It typically takes 1-2x the video's duration, so for example, for a one hour video, expect to wait approximately two hours to finish processing.

可以通过三种方式使用标题:Captions are used in three ways:

  • 观看视频时,您可以选择查看视频底部的标题。When watching a video, you can select to see captions at the bottom of the video.

  • 通过将标题连接到窗体,可在 "脚本"窗口中找到记录。Captions are concatenated to form a transcript, which is available in the transcript window.

  • 对标题编制了索引,因此您可以通过使用deep search搜索来直接转到视频中的特定位置。Captions are indexed, so you can go directly to a specific location in a video by searching using deep search.
