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. Personalise it to your needs and preferences, whether that’s through choosing from the many voices available, or through customising 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, MND, stroke, or traumatic brain injury). Proloquo4Text can be used to produce speech by anyone who can type and spell.

One of the best apps going

I've used proloquo2go and moved to 4text when it was released - it's very adaptable. The short cuts allow for quick communication in busy situations. The other features all make for a great application for literate users who have little to no problem with fine motor skills. I would give it 5 stars but they're continually improving with the end user in mind - so there's always a 5 star rating to aspire too :)
