Proloquo4Text is a text to speech app for those who cannot rely on their voice to speak. The app is laid out on a single screen to reduce the effort of typing. The layout enables easy, daily conversation and quick access to your most common phrases. Personalize it to your needs and preferences, whether that’s through choosing from the many voices available, or through customizing your screen layout.

Available for iPhone, iPad and Apple Watch.

Speak Up with Text-Based AAC

Not being able to speak isn’t the same as having nothing to say. Children, teens and adults who can’t (always) speak can use this Augmentative and Alternative Communication (AAC) app for iOS to communicate confidently. If you can write, you can use Proloquo4Text – it’s that easy.

Make yourself heard

You’ll love the freedom this Text to Speech app gives you to express yourself. Proloquo4Text’s intuitive word and sentence prediction uses what you type to anticipate what you might say next – helping you save time and effort.

But what really makes this AAC solution stand out is the single screen layout, which keeps everything at hand. Proloquo4Text’s versatility makes it useful for people with autism, cerebral palsy, ALS, and a range of other diagnoses.

Behind the scenes with Lost Voice Guy

Proloquo4Text is a very powerful app. I especially like how I can have conversations at the same time without losing any text.
