Letterboard: Spell and Speak

Letterboard is a communication board for people who spell out what they want to say. Tap large letters to build a message, then tap the speaker to have your phone or tablet read it aloud. Nothing is spoken until you choose. WHO IT IS FOR Letterboard is made for non-speaking and minimally speaking people who spell to communicate, including autistic people and people with apraxia of speech, and for everyone who supports them. It starts from presuming competence: not speaking is not the same as not thinking. • Spellers and their communication and regulation partners (CRPs): a partner can hold the phone or tablet at whatever angle the speller needs, and the letters never move • Families, teachers, therapists and speech-language pathologists using letterboard approaches such as Spelling to Communicate (S2C), the Rapid Prompting Method (RPM) or the Spellers Method • Spellers moving from an alphabetical letter board to a full QWERTY keyboard • Anyone using a letter board as AAC (augmentative and alternative communication) who wants their words spoken aloud • No word prediction or autocorrect: every letter is the speller's own LARGE, CLEAR LETTERS • The board fills the screen and keeps every letter in the same place when you rotate the device • Alphabetical order, or a phone-style QWERTY keyboard with numbers and capitals/lowercase • Move letters, add symbols, rows and columns to match the board you already use • Six colour themes, custom colours and your own saved palettes WRITE AND SPEAK • A message line with undo, cursor movement, space, backspace and clear • Speech uses the voices installed on your device, with a voice and speed for each language • Show the message in large text for someone to read • Save phrases you use often and insert them with one tap NUMBERS AND MATHS • A number board that types into the same message, one tap away from the letters • The person writes the whole sum, including their own answer, and it is read aloud as written: "5 + 3 = 8" • Square roots, powers, brackets and comparisons are read as words • An optional answer check for helpers, off by default, shows a silent ✓ or ✗ after the answer has been spoken PRIVATE BY DESIGN • No internet permission, no accounts, no ads, no analytics • Messages, phrases and settings stay on your device • Speech is produced by the speech engine installed on your device; that engine has its own privacy policy
