Audio

The audio alternative reads aloud the text in the original content. This also includes alternative descriptions for images, if they are provided.

The audio format is saved as an MP3. MP3s are compressed, high-quality sound files that can be played on any computer or mobile device.

Audio formats fail, if the original document contains more than 100,000 characters.

Why use audio?

Not only does audio benefit individuals with visual impairments, research has also proven that audio can increase learning (Boyle et al., 2003).

Maybe these sound like you. If so, audio is a good option.

  • You prefer to listen than read.
  • You’re an auditory learner.
  • You want to read and listen to the content at the same time.
  • You have a lot of material to read and find your eyes get tired.
  • You read on your commute.
  • You don’t want to, or can’t, carry print materials for any length of time.
  • You have a visual impairment.
  • You want to adjust the speed of the audio.

    Most players allow you to adjust playback speed. For example, Windows Media player, VIC, Audacity, and iTunes.

Electronic braille

The electronic braille alternative creates a BRF file that can be read on a refreshable Braille display (RBD), other Braille reading devices, or within a Braille software like Duxbury. 

Think of a Refreshable Braille Display (RBD) as a monitor-less computer. Most RBDs can connect to internet, create documents, access calendar, and a lot of the basic functionality a computer provides. RBDs can be a standalone device. They can also be connected to a smartphone, iPad, or laptop. Most RBDs are limited to reading one line of Braille at a time.

Semantic HTML is available offline on your mobile device, if you don't close your browser.
