Abstract

Stemsyl is a phonetic stem, position, and color system for reading, writing, and typing languages by sound. This version is for American English, and variations extend it to other accents and languages. Each syllable is drawn as a short horizontal stem carrying up to three vertical ticks: the consonant before the vowel, the vowel, and the consonant after it. A tick can be above the stem, centered across it, or below it, and its position together with its color names exactly one sound. The 24 consonants form eight color families of three, and the 14 vowels use seven colors in up to three positions each. Numerals are dice-like patterns on a 3 × 3 grid, and a diamond marks names.   Because every sound is a choice of position and then of color, Stemsyl can be typed with two taps on a 3 × 3 grid of keys. The document specifies the script and several ways of typing it: a keyboard with a key for every sound; the two-tap 3 × 3 keyboard; a watch keyboard with a full editor that reaches its other pages of keys by holding the middle key of an edge; and a 3 × 3 keyboard for Latin letters. It also covers showing the English word under a written word when exactly one English word has those sounds, a 271,173-word pronouncing list, and many variations. It is published as prior art, free for anyone to use.
