“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

Proloquo2Go: If you are looking for Proloquo2Go for iPhone and iPod visit the Proloquo2Go web site.

Proloquo is a multilingual speech and communication solution for Mac OS X that provides: (1) a full-fledged communication system (AAC) for people who cannot speak; (2) provides speech feedback in any application while typing for children and people with learning disabilities; (3) can serve as a talking word processor; (4) 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, Czech, Canadian French, French, German, Italian, Dutch, Flemish, Icelandic, Spanish, Polish, Portuguese, Brazilian Portuguese, Danish, Norwegian, Finnish, Swedish and Turkish. 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 communication 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.

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 also includes 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.

Upgrading: Version 2.0 is a free upgrade for existing Proloquo users. They can also contact us for an Infovox iVox activation code for their current language.
