This article will help you to understand and use the automatic speech recognition and closed captioning features of Echo360 to improve accessibility for your learners.
What is Echo360 ASR?
ASR stands for “automatic speech recognition” and is a service provided by Amazon that uses computers to translate speech into text and sync the text with the video.
All videos produced or uploaded on the Echo360 platform now have transcriptions which can be edited and enabled as closed captions. Videos added before this feature was enabled (Winter 2020) will NOT have transcriptions.
Echo 360 ASR accuracy
An ASR service is not likely to meet the accuracy levels required of closed captions for hearing impaired individuals. You will find this particularly true in the cases where
- Background noise interferes with the recording
- The speaker’s voice is at a low volume in the recording
- The speaker’s pronunciation of certain words presents difficulty for the speech recognition software
All that being said, transcriptions can be applied much faster than closed captions and typically cost less to generate. Transcriptions may provide a “good enough” solution for providing both visual and audio content for lectures.
Logging into your CU Echo360 account
You can log in to the Echo360 centre here:
Once you have logged in, you will be able to see all of the content you have access to and that you can view is found on your Echo360 Library page.
A screen grab example of what this might look like is shown below:
This is sometimes also referred to as your “Media Library” or “Content Library”. The Library page combines all of the Echo360 media you have access to in one place.
