SpeakUp AAC vs Prism

SpeakUp is a free AAC (Augmentative and Alternative Communication) app designed to help non-verbal individuals express themselves with ease. Type any phrase and speak it instantly, or browse pre-made common phrases organized by category. Save your most used phrases to favorites for quick access, and build confidence in communication with two built-in practice modes. SpeakUp is completely free with no ads and no subscriptions because everyone deserves a voice.

Prism AAC helps nonverbal children and adults talk. Tap pictures, build sentences, and hear them spoken aloud — in 25 languages, on iPhone, iPad and Apple Watch. Core communication is free and works without an account or an internet connection: communication boards with 22 categories, a keyboard with word prediction, saved phrases, device voices and cached speech, on-device AI, visual schedules, therapeutic games and emergency communication. No ads. No data harvesting. Your child's voice never depends on WiFi. PRISM AAC CLOUD — optional subscription US$4.99 per month adds a monthly allowance of 50,000 newly generated natural-voice speech characters and 100 cloud AI requests. Cached playback and device voices never use the allowance. The allowance resets on the first day of each month (00:00 UTC), and there are no overage charges. The same subscription works on iOS and on the web with one account. Boards, saved phrases, cached speech, device voices, on-device AI and emergency communication stay available without a subscription and after one ends. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically each month unless it is cancelled at least 24 hours before the end of the current period, and it can be managed or cancelled in your Apple Account settings after purchase.
