Sayella vs Spoken

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.

Spoken is an augmentative and alternative communication app for people who cannot use speech because of nonverbal autism, aphasia, stroke, or other speech and language disorders. Users compose messages on a mobile device, and the app reads them aloud with text-to-speech. It predicts words and can offer suggestions that adapt to a user’s communication. Access methods include touch, typing, handwriting, drawing, eye tracking, VoiceOver, and TalkBack. The free base version includes an attention button, large text display, large print mode, dark mode, and phrase sharing. Premium adds saved phrases, customizable lifelike voices, and a quiz that tailors suggestions to familiar people, pets, and places. Spoken runs on iOS and iPadOS 11 or later, Android 5.1 or later, and Apple Silicon Macs. Internet access is needed for all features, though limited functions work offline. The automatic Premium trial lasts around 600 words. The base app remains available afterward; Premium costs $12.99 a month, $99 a year, or $249, paid once website purchase.
