SPELLBOX

• SPELLBOX turns the FM-1 into a talking spelling toy with a vintage ten coefficient LPC voice at 8 kHz.
• Five word games run in English across four levels, chosen with PRESETS and set with SELECT.
• SING and LETTER SYNTH make the keyboard an instrument where words and letters are sung at each key's pitch.
• Held keys sustain the vowel, OCT- and OCT+ shift the octave, and both modes also respond to MIDI.
• SPEAK pronounces anything you type, using a twelve thousand word dictionary, common endings, then letter to sound rules.
• The VOICE page sets pitch, speed, chip clock and speaker tone, while the BEND page adds corrupted coefficients, stutter, flat intonation and bit crushing.
• GLO switches all the BEND effects on or off at once, and MASTER sets the volume.
• SAVE keeps the level, the settings and the chosen letter, and the vocabulary holds a hundred words of up to eight letters.

Its modes

SPELL

The box says a word, you type it on the alphabetical keyboard and press ENTRÉE, scoring over ten words.

LETTER

Every key speaks and shows its own letter.

SAY IT

A word appears for you to say aloud, then ENTRÉE plays it and later you spell the same words.

SECRET CODE

Type a word and ENTRÉE swaps each letter for its opposite, and coding again decodes it.

MYSTERY WORD

Guess the hidden word letter by letter with seven mistakes allowed, tried letters staying lit.

SING

The keys become notes and sing the chosen word at each pitch, holding the vowel while you hold the key.

LETTER SYNTH

Each key sings its own letter at its pitch, or SELECT puts one letter across the whole keyboard.

SPEAK

Type words with OCT+ for space and REC to erase, then ENTRÉE speaks them aloud.

VOICE

Set PITCH, SPEED, the chip CLOCK and speaker TONE under HOME.

BEND

Set BEND, STUTTER, MONO and CRUSH under ENV for circuit bent sounds.
