Section 508 requires a text equivalent of audio information be available in online instruction.
Whether you are using Wimba’s Voice Tools, Podcasting or uploading mp3s to your online course remember to include a textual representation or a text equivalent of the audio content. This is as simple as providing a transcript so that someone who is deaf, hard of hearing, who has an auditory processing deficit or for whom English is a second language can access to the content.
The easiest way to do this is to create audio from lecture notes or documents that you have already created.
If you are creating the audio first and then the transcript you will soon discover the transcribing audio to text is very time consuming! If your campus doesn't provide a transcription service you might want to look into an off-campus transcription service.
Some instructors use a voice recognition program such as Dragon NaturallySpeaking while they are recording the audio lecture. This way they create the audio and text portions at the same time.
If you have lecture notes that you would like converted into audio but don't have the time to create the audio (and don't mind a computerized voice) you might want to look into purchasing a screen reader that will convert text to an MP3 file. NaturalReader is one option that will convert text files up to 4 million letters to MP3 or WAV files in a matter of minutes.
The Law Section 508 was enacted to eliminate barrriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals.
