Audio (CD, MP3, WAV, Digital Recorders)
There may be some students who have permission to record lectures, to aid memory and note taking. Typically this is done using a modern digital recorder, which is a solid state device (no moving parts), and stores the audio files as either MP3 or WAV format.
It is also possible to have Word documents read aloud on a computer, or converted to audio files using software such as Claroread Plus or TextHelp Read & Write Gold. The resulting speech playback and audio files can use a variety of computer generated voices which are of a very high standard nowadays.
