Transcription and Captioning

While captioning and transcription were originally designed for individuals who are deaf or hard of hearing, many people benefit from seeing the spoken word represented as text, including those who are:

listening to someone speaking in a language that is not their native language
situations where the sound quality is not good or there is a lot of background noise
those who benefit from seeing as well as hearing
those who may benefit from having a lasting transcript.

Automatic Transcription and Captioning

Transcription is the process of converting the spoken word to text. Transcription can be done by computer-based speech recognition technology, usually referred to as automatic transcription. Similarly, when captions for a video are computer generated, they are referred to as automatic captions. Because automatic transcription and captioning use speech recognition technology to produce a transcript, accuracy can vary significantly depending on several factors including sound quality, background noise, technical terms used and the speaker’s accent.

Live Transcription

Alternatively, live transcription can be done by a professionally trained transcriber, often referred to as CART. If a participant requests CART services as an accommodation for a live event, automatic transcription should not be substituted since the accuracy cannot be guaranteed. If you are producing videos, it is important to check the captions for accuracy and edit as needed or have the video professionally captioned.

To be able to view a transcript for your personal use during a live or virtual event, Otter.ai and Google Live Transcribe are options. These tools work best if the speaker has a microphone or if you are in close proximity to the speaker. Both tools are available on mobile devices.

Automatic transcription using Otter.ai

Similar to Zoom Live Transcription, Otter.ai can provide a transcript in real-time during virtual meetings or classes.
