“Proloquo provides the kind of augmentative communication I always hoped for. Now, for the first time after I lost my own voice due to ALS/MND, even new acquaintances and older persons understand me with ease. People like my new voice. I like getting rid of the additional hardware and using just my PowerBook and Mac OS X. Without Proloquo for speech and KeyStrokes for typing I would no longer be able to work!”

Walter Pfrommer, medical adviser in a healthcare IT project

About Proloquo

Proloquo is a multi-purpose, multilingual speech solution for Mac OS X that provides: (1) a full-fledged communication system (AAC) for people who cannot speak; (2) improves accessibility of Mac OS X for people with visual impairments; (3) provides speech feedback in any application while typing for children and people with learning disabilities; (4) can serve as a talking word processor; (5) provides text to speech for people who prefer listening to reading; (6) can be used as a tool to learn the pronunciation of foreign languages; (7) provides an advanced, multilingual speech engine for our KeyStrokes® on-screen keyboard and our SwitchXS® switch access solution.

Proloquo includes natural-sounding Infovox iVox voices for a language of choice. The languages currently available are American English, British English, American Spanish, Canadian French, French, German, Italian, Dutch, Flemish, Spanish, Portuguese, Brazilian Portuguese, Danish, Norwegian, Finnish and Swedish. Infovox iVox provides voices that work not only in Proloquo but system-wide. Finally, Proloquo of course works with all the built-in voices of Mac OS X.

Proloquo is different from Apple’s excellent VoiceOver technology for Mac OS X Tiger in several ways. VoiceOver is a screen reader primarily intended for people who are blind. Proloquo, instead, is a multi-purpose speech solution that also includes certain features geared towards people with limited vision (such as the ability to speak what is below the cursor and to echo what the user types). Additionally, Proloquo works with high quality voices in multiple languages and works on both Mac OS X 10.3.9 (Panther) and Mac OS X 10.4 (Tiger)

Proloquo can be used to create a complete personalized Augmentative and Alternative Communication (AAC) system using simple drag and drop (or copy and paste) of phrases into lists organized by topic. Proloquo can also be combined with LayoutKitchen®. With LayoutKitchen users can design their own speech panels for Proloquo with colorable and resizable buttons containing text and/or images in a variety of formats.
