UW-Madison Zoom - Live transcription

Live Transcription (built-in Otter.ai service) provides robot transcription services, which enables speech to text transcription in meetings and webinars.

Important/Warning: Be aware that because this service creates machine-generated transcriptions, their accuracy will not be perfect. Most automatic speech recognition (ASR) transcription results in approximately 70-80% accuracy.

This feature (including Closed Captioning) is enabled by default for all UW-Madison Zoom users.

Overview: Live captioning within Zoom Meetings and Webinars come in two options:

Note: Only the host of a meeting can initiate live transcriptions. If you are scheduling a meeting that you will not be present for, you should designate an "alternative host" when creating the meeting. The "alternative host" will become the "host" if you are not in the meeting and be able to initiate live captioning. Instructions on "alternative hosts" can be found in this Zoom article.

Prerequisites

Note: Live transcriptions cannot be accessed using the web client (browser) regardless of type.

Live transcription limitations

The accuracy of Zoom’s live transcription feature depends on many variables, such as but not limited to:

This feature is not available in Breakout Rooms and does not create subtitles in the Zoom recording. Subtitles only appear during the live meeting. Hosts who want subtitles to appear in the Zoom recording need turn on Zoom Audio Transcription.

Because of these limitations, if you are required to use speech-to-text support for any compliance needs in your meetings and webinars, we recommend using a manual captioner who may be able to guarantee a specific accuracy.
