This increased use of video in education as an instructional medium can be observed especially in online courses. Captioning and/or transcripts, make these resources accessible to people with disabilities and they also help all students including international learners. However, creating transcripts/captions manually can take lot of effort, both in terms of time and money.
Automatic Speech Recognition technologies have improved rapidly in the last couple of years. Both IBM and Microsoft have reached Word Error Rate (WER) almost in par with a professional human transcriber (Fogel, 2017; Lant, 2017). Transcript accuracy can be measured with WER and this is calculated using the formula: WER = (Substitution + Deletion + Insertions) / total number of words (Apone, Botkin, Brooks, & Goldberg, 2011).
Given the legal obligation to create accessible content it is important that new technologies and their capabilities are explored. In this presentation, I will be sharing some work in progress of assessing six automatic transcription services to explore how useful the current automatic transcription software could be in creating learning materials for the build environment sector.
