Flexspeak AAC vs Sayella

Flexspeak AAC is an augmentative and alternative communication app designed for multilingual communication, available on Android, iOS, and web. Translate Mode supports real-time translation in 30+ languages, letting a user type in one language and speak in another. Speech output works with touch and an on-grid keyboard, and layouts can be customized using a hybrid symbol system. AI-assisted tools help users and clinicians adapt vocabulary, layouts, and symbols while keeping them in control. Changes made on one device automatically appear across devices, and the pricing page says communication works offline. The AAC app costs $299.99, paid once and includes full AAC functionality, cloud sync, 2,400+ preset words, and offline communication. A free Evaluator License for one professional includes up to 10 visuals per month and real-time translation in 30+ languages. Flexspeak says its AI features do not train on user data and describes its service as FERPA- and HIPAA-aligned. Voice cloning requires written in-app consent; recordings are sent to ElevenLabs and are not stored by Flexspeak. A 30-day trial is listed.

Sayella is an AAC communication app for nonverbal and minimally verbal children and adults. It turns pictures and words into spoken messages, with speech available offline on iPhone and iPad. Its customizable boards use a research-based core vocabulary, fixed button positions, and selectable board sizes. The app supports touch, VoiceOver, and TalkBack. Boards can be imported and exported in Open Board Format, including.obf and.obz files. Users can generate symbols from words or photos; free accounts include two generations, while paid plans allow unlimited generations. Sayella says AI requests go through Vercel AI Gateway to Google's Imagen and Gemini image models. It states that synced board data is encrypted, analytics do not receive AAC content, and personal data is not sold. Free costs nothing, billed forever, for one child and one device. Monthly costs £7.99 a month, Yearly costs £59 a year, and Lifetime costs £189, paid once. The download page lists Android and browser access as coming soon.
