Multi-award winning app for people with speech disabilities who need a sleek, simple and smart way to communicate! Predictable allows a person to type a message using the intelligent word prediction, which learns their pattern of use, making prediction even faster. Use Nuance voices, record your own voice saying familiar phrases or use your voice banked ModelTalker voice.
Save phrases in the phrase bank for quick access; add items to Favourites and set up the features for a more personalised experience. Switch accessible; people can use the app with significant physical disabilities using one or two switches.
“Liberating” (Peter, Cheshire, UK)
“Predictable works for me because it is my only means of communication” (Maureen, London, UK)
Predictable 4 now allows people to use ModelTalker voices for an even more personal experience. People can bank their voice and then directly use it within Predictable, in an exclusive feature for this app!
Now with Skype integration; specialist subject dictionaries; YouTube, iTunes and more – this best-selling app is now even better.

Customer Reviews


One of the better text to speech apps, but still not fully satisfying as far as switch access.

Discovered a shocking example of antisemitism in my version. Type "I hate" and look at the word prediction bar. Awful. Hope that developer has been fired.
