Loud Story was a book idea I was developing a while ago which pretty quickly ran out of steam. It plays with the neat kind of accidents that can occur when predictive text goes wrong: when pint accidentally becomes riot, kiss becomes lips, baker becomes cakes and all that stuff. Textonyms, these words are apparently called.
Nowadays of course anyone with any self-respect has an iPhone - or at the very least a Blackberry- and so uses a miniature QWERTY keyboard, making the whole idea redundant. Which is a shame.
