I very seldom post links to news sites, especially those which are full of adverts. However this story is so refreshing and encouraging that I think it worth the link.

AssistiveWare’s Proloquo2Go, an accessibility app for iOS which provides a voice for those who cannot speak themselves, is proving a commercial success. Although it seems expensive, its developers are covering the costs of licensing voices, symbols, and a grammar engine. The net result is a huge step forward for its 22,000 users.

I hope that it encourages other developers to enter this important market.

(Thanks to Adam Banks and @SteveALee for drawing my attention to this.)
