About

VoiceBridge AAC

Read full description

VoiceBridge is an AAC (Augmentative and Alternative Communication) app built for iPad that helps nonspeaking and minimally speaking individuals communicate — and helps the people supporting them make clinically informed decisions. COMMUNICATE • Clear, uncluttered tile grids designed for fast, confident selection • Sentence bar with natural text-to-speech output • Word search that highlights the path to any word, so partners can model without hunting PERSONALIZE • Fully editable tiles: text, images, recorded audio, and video • Copy and customize vocabulary sets for different communicators or contexts • Share vocabulary sets between devices with a QR code CLINICALLY GUIDED • Language Sampling: capture a session, then generate a professional report with measures like total number of different words (TNDW), mean length of utterance (MLU), communicative functions (requesting, commenting, greeting, protesting), and communication modalities — exportable as a PDF • Insights: on-device usage details that show which words are actually being used, so vocabulary decisions are based on evidence, not guesswork VoiceBridge was built alongside speech-language pathologists to support real therapy workflows — from everyday communication at home and school to structured language sampling in the clinic.
