Transcripts - accessibility.

• Manual transcripts: Sub-contract transcripts, e.g. via internet service
  • sub contract students
  • There are various internet-based services that accept submission of e.g. mp3, and return a transcript within a certain time-frame.
  • Amazon Mechanical Turk. (https://www.mturk.com/mturk/welcome). It was suggested that Mechanical Turk could be an option for providing transcripts, but the view that MT is essentially a 'virtual sweatshop' is not unfounded: See http://en.wikipedia.org/wiki/Amazon_Mechanical_Turk#Criticism
• Automated transcripts
