Audio-based access to e-learning

What for?

Learning processes in which sound is the main source of information

Students with perceptual auditory learning styles

Hands-busy, eyes-busy and mobility-required situations

The device has speech input/output capabilities but lack of usable displays or keyboards

A disability does not allow a person to make use of a visual display
