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.

Proloquo4Text is the leading AAC solution for literate adults, teens and children. It is used by people with a wide range of diagnoses, including developmental disabilities (like autism, apraxia, and cerebral palsy) and acquired disorders (like laryngectomy, ALS, stroke, or traumatic brain injury). Proloquo4Text can be used to produce speech by anyone who can type and spell.

Sentence Banking

I’ve conducted hundreds of AAC assessments and have to say how important having P4Text in my toolkit is. Adults that insist on original speech take too long to generate sentences from scratch. 90% of the time, the other person walks away before it’s ready. Sentence banking allows the user or helper to anticipate events and prepare what to say ahead, so that sentences are ready with a press or two of the screen.

A neurological disease has taken my speech. Thanks to the speech people at Johns Hopkins, I discovered the power of Proloquo4Text. I type. It speaks. It helps me feel whole.
