The restorer's note
The robot voice, from the company that already owned the mathematics of speech. Salo built it for secure comms; musicians would have loved it, had they ever been let near one. Serial 0088 — an early, low-numbered unit, restored with its bands untouched.

Demonstration recordings, prepared at the bench.
The voice, played
The note reads dry for six seconds; then the Internal carrier takes it — a held line sung by the filterbank, sixteen Bands wide — and the reading becomes the machine's.

Eight bands to thirty-two
Bands step from eight — barely words — to sixteen, then thirty-two, the reading sharpening at each move: the resolution of the filterbank, heard arriving. Mode then switches to LPC, and the same voice is carried by the all-pole model instead.

Spoken through the pad
Carrier switched to Sidechain: the pad is made to speak. Sibilance rises to 80 % and the consonants return; Formant is pushed up seven semitones, then down; Attack and Release open at the close and the words smear.
