Most AAC/SGD apps and devices from Tobii-Dynavox, PRC, SmartBox, Saltillo, and others that are based on Windows or Android will be able to use your ModelTalker voice. One caveat: The kind of Windows apps that are installed via the Microsoft app store does not work with ModelTalker voices, because our Windows voices are compliant with Microsoft’s SAPI 5 standard and Microsoft app store software is not.
On iOS devices (iPad & iPhone), ModelTalker voices work with Predictable and ChatAble apps from TherapyBox and TD Talk from Tobii Dynavox. Predictable is a full-featured AAC application used by many ALS patients. ChatAble is more geared toward children. TD Talk is a free iPad application that provides the ability to type text and have it spoken in your ModelTalker voice. TD Talk is one component of the full-featured TD Pilot iPad-based AAC device.
Our voices also install as system voices on Mac desktop and laptop computers for macOS 10.8 and above. There appears to be only one application for Macs (Proloquo4Text) that has SGD features. However, Macs integrate TTS voices with most text-based applications and can be good for testing voices.
If you are thinking of using a specific device or application, always check with the manufacturer to be sure you have the most up-to-date information from them, as features change over time.
