Speak up with text-based AAC


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.

Now available: Proloquo4Text for Mac

Proloquo4Text is also available now on the Mac App Store. They want to give people the freedom to choose on which device they prefer to use Proloquo4Text. You no longer have to switch between devices if you are using your Mac laptop at work or at school.
