Scene Speak allows an image to be edited with active “hotspots”. A hotspot is an area of the screen that can “sound areas” that can be selected and used as a means of communication. An image can have multiple “hotspots” that can be edited to add sound, text labels or link to another visual scene. In addition, Images with text can be then can be added into “books” by theme or area of interest. Scene Speak is a wonderful communication tool for those with Autism, Aphasia, Apraxia, developmental disabilities or anyone wanting to enhance receptive language or visual memory. FEATURES INCLUDE: * ADD CUSTOM IMAGES from your home computer, the iPad camera or from the built in Internet search feature to create contextually relevant scenes. * RECORD YOUR OWN VOICE to the “sound areas” or use one of the five preloaded voices in the TTS feature. * MULTIPLE HOTSPOTS can be added to a scene. Hotspots can include: sound, text labels or can link to another scene. * CREATE SOCIAL STORIES by grouping scenes into books. * TEXT CAN BE ANIMATED by recording voice in-sync to the color change of text (text changes from black to red and back to black). * PAGES CAN BE LOCKED /unlocked as needed to prevent user from going to another page. * FILE SHARING: you can backup your saved "Books" and "VSD's" on your home computer or you can share them with a person with the same application. * BACKUP AND RESTORE VIA iCLOUD to prevent loss of created scenes or share saved information to devices on the same iTunes account. * PASSWORD PROTECTED SETTINGS MENU to prevent access to editing features and settings. How does it work? Personalized mages can be uploaded to the app. from your home computer or through an online image search. The images can then be resized and active “sound areas” can be added. The application allows both the number and size of the “sound areas” to be customized. Spoken messages can be added to the “sound areas” by using the Text-To-Speech feature, with one of five preloaded voices, or you can record your own voice to the “sound areas”. User can also add text to the sound area as a way of reinforcing receptive language acquisition. A scene can also be linked to another scene via the hotspot. This creates a unique opportunity to create a scene based communication system for those with communication delays. In addition, a scene can have text added directly to the bottom of a page. Once a visual scene is created with active “hotspots” or text, scenes can be added into “Books”. Books can be created and images grouped into the book by a specific theme or area of interest. Multiple books can be created within the book library and as many visual scenes as needed added into the “book”. For example: you may want to create a “Book” titled “My Home”. Within that book may want to include images of different rooms in the home. Within those images you can add “sound areas” to label different objects or people that are represented in those images. A bedroom scene may say, “go to bed” when the bed is touched or “read a book” when a bookcase is touched. * The app. comes preloaded with eleven generic scenes that can be edited and sound areas added. Scenes include: Kitchen Bedroom Child’s Bedroom Living room Bathroom Park Doctor’s office “What Hurts?” (Boy, girl, man, woman).

Verdict

The call

The clearest difference is price: Scene Speak at $9.99 against Predictable's $159.99. Scene Speak also leads on review sentiment (76% vs 68%) and iOS requirement (8.2 vs 15.5). Predictable's advantage is rating (4.5 vs 3.3) and ratings volume (203 vs 9). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Predictable holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Predictable has 203 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 68% of Predictable's written reviews are positive against 76% of Scene Speak's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Predictable ships an update every 2 months, Scene Speak every 4 months. The most recent releases landed on September 26, 2026 and September 10, 2026 respectively.
