Optophone

The optophone is a device, used by the blind, that scans text and generates time-varying chords of tones to
identify letters. It is one of the earliest known applications of sonification. Dr. Edmund Fournier d’Albe of
Birmingham University invented the optophone in 1913,[1] which used selenium photosensors to detect black print
and convert it into an audible output which could be interpreted by a blind person.
