Build and speak a message
Choose words from clear boards and folders. Each selection can be spoken immediately and added to the message bar for a complete thought.
Communication that feels personal
SPARK combines familiar communication boards with flexible editing, private prediction, and settings that adapt to the person using it.
How SPARK works
Find and reuse language
Search across built-in and custom vocabulary, save useful phrases, and quickly return to recently spoken messages.
Create the right vocabulary
Add or edit words, phrases, folders, images, emoji, colors, pronunciations, and recordings. Drag items into a familiar order or move them between boards.
Choose how SPARK responds
Adjust the device voice, speed, pitch, text size, columns, symbols, touch delay, automatic navigation, and word prediction from Settings.
SPARK in action
Explore the current interface—not a mockup or planned design.
Folders and everyday words remain visible in a consistent grid, with the message and main actions always at the top.
