Proloquo™ is a multilingual Augmentative and Alternative Communication (AAC) solution for Mac for people who have difficulty speaking or cannot speak at all. The software also offers features for users with limited vision or learning disabilities such as speech feedback in any application while typing and the ability to speak what is below the cursor. Note that Proloquo is for Mac OS X and is different from Proloquo2Go, which is for iPhone, iPad and iPod touch.

Proloquo also provides a talking word processor and an advanced speech engine for our KeyStrokes™ on-screen keyboard and our SwitchXS™ switch access solution. 

Proloquo includes layout editor LayoutKitchen™, with which users can design their own speech panels with colorable and resizable buttons containing text and/or images in a variety of formats. Proloquo also comes bundled with 5 Infovox iVox™ voice credits. With these credits you can purchase Infovox iVox voices you like in any language. If you want to use additional voices, you can purchase extra voice credits. Infovox iVox offers the best naturally-sounding voices for Mac in a wide range of languages.
