New app for children who are unable to speak


New technology promises to give thousands of children who cannot speak a voice.

An app called Proloquo2Go allows six-year-old Ruby Dunn to tap on symbols on a tablet computer - and then have a sentence read out in a child's voice.

The software, which features the voices of two British children, is among a number of innovations now helping children with special needs.
