"Alexicom AAC" is an AAC App for iOS. Alexicom is not device-dependent if one hires the service.
See "Free features include" and "Enhanced services (paid services)" below. Publish your Alexicom augmentative communication pages to your iPad, iPod, or iPhone and take them anywhere. Communication pages with text, images, and AT&T Natural Voices speech output can be downloaded directly from the Alexicom server or imported from your PC or Mac using iTunes. Once the pages are on your device, a data connection is no longer required. (Full access to the Alexicom server requires an active Alexicom account, however this app includes 36 demo pages, which are accessible and editable immediately.)
Alexicom AAC for iPhone/iPad lets you use your iPhone, iPad, or iPod Touch as an augmentative communication device. We offer over 2,500 pre-made pages and over 25,000 real photo and SymbolStix images in our public libraries, which include these pre-made page sets: ChildPre (A,B,C), Child1 (A and B), Child2, Child Intermediate, PicSpeechmaker, Speechmaker, Adult1, Adult2, Healthcare, StoryMaker, Core 280, Child Home, Teen Home, and Spanish Child1. You can easily import these pages into your own online library, customize them, and/or create your own pages. AT&T Natural Voices and eSpeak TTS offer text-to-speech output in 68 voices and 30 languages.
Alexicom is not device dependent. Your pages can be accessed from any Mac, Linux, PC, iOS device, or other device with a standard web browser or app market. Pages can be shared between SLPs and parents and edited without taking the device away from the user. Publish your pages to multiple devices. Easily print your pages and even use them on an interactive white board.
