Why Aural rendering of documents is necessary

Aural rendering of documents is mainly used by the visually impaired. Some of the situations in which a document can be accessed by means of aural rendering rather than visual rendering are the following.

• Learning to read
• Training
• Web access in vehicles
• Home entertainment
• Industrial documentation
• Medical documentation

When using aural properties, the canvas consists of a three-dimensional physical space (sound surrounds) and a temporal space (one may specify sounds before, during, and after other sounds).
