With access to the full Pics for PECS library, multiple voice output options, and multiple languages, the PECSTalk™ app can be individualized for your learner’s needs. With PECSTalk™, users can construct a multi-picture Sentence Strip™ via a dedicated Sentence Starter™ page and create up to 30 digital PECS book pages for the in-app voice to speak. The digital display is similar in layout to a traditional PECS Communication Book while accommodating the more robust vocabulary of a Speech Generating Device (SGD).

By converting pictures and text into spoken language, the PECSTalk™ app empowers non-speaking learners to fully participate in their school, home, vocational, and community settings.
