Transcripts and captions and for lecture/meeting recordings can be generated using Automatic Speech Recognition (ASR) technology which is included with Microsoft Stream, Zoom and Echo 360. Since these transcripts are automatically generated they should be thoroughly checked and edited. This guide covers how to generate transcripts and transfer those transcripts to Echo 360 for subsequent publication within a Moodle course.
Please note that automated transcripts will not be generated for recordings shared directly to individuals or by sharing a link to the recording(s). Recordings must be published to a course/section in Echo 360.
Using Echo 360 automatic speech recognition to generate a transcript/captions
All Echo 360 recordings will be transcribed using automatic speech recognition when they are published to a course. Where the Echo 360 AI is confident in the accuracy of a transcript it will also be automatically applied as captions (sometimes known as subtitles). Please note that the process of assessing accuracy is an automated process. See this Echo 360 guide to understand the difference between transcripts and captions.
How long does it take for a transcription to appear?
It takes at least 30 minutes for a video to receive automatic transcriptions, longer for videos that are more than an hour in length and/or if the transcription service is processing a large number of requests at the time. Further details re. transcription can be found here.
The automatic speech recognition transcription service is likely not going to meet the accuracy levels required of closed captions for hearing impaired individuals. Those with such a requirement should contact the LSE Disability and Wellbeing Service (DWS) for access to enhanced captions.
Generating and editing an Echo360 automated recording transcript
If automated captions have previously been applied to your recording, then your newly edited transcript will override the automated captions. Click “Apply to CC”. To see the applied transcript in action, play the video in the playback panel, with the CC button turned on.
Using Zoom to generate transcripts/captions for recorded Zoom meetings
All Zoom meeting recordings can be transcribed automatically, but the meeting does need to be recorded and the audio transcript setting needs to be enabled on your Zoom profile before you schedule/start a meeting. See the using audio transcription guide to learn how to enable this on your Zoom profile.
Transferring your Zoom generated transcript to Echo 360
If your Zoom recording will be manually uploaded to Echo 360 or the transcript fails to automatically transfer, the transcript created by Zoom can be uploaded to Echo 360 to be applied to your recording. The transcript can be checked and edited within Zoom before uploading to Echo 360, or you can edit using Echo360 as above.
To download automatically generated captions from Zoom, go to the Recordings section of your Zoom profile page, select the recording, hover your mouse over the transcript and click the audio transcript download button (downward arrow icon).
