Description

What is Dectalk

Dectalk was a speech synthesizer and text-to-speech technology developed by Digital Equipment Corporation in 1984, mainly based on the work of Dennis Klatt at MIT.

The Dectalk Express what connected to the serial port and would speak what was being “printed.”

Dectalk Express

The synthesizer can process text and produce speech with nine different voices. The Dectalk engine includes a parser that gives users fine control over the synthesized speech’s quality, pitch, and intonation. Dectalk can also be programmed to play phonemes and sing with quite a realistic expression.

The command syntax for musical coding sequences is:

Timing

Latency
There is a latency of 200 ms between the trigger and the start of the speech. This latency is very consistent, allowing the speech to stay in the tempo even if not precisely on the beat. The firmware uses the gate going down to stop the speech, preparing the chip for the next utterance, so when sequencing some stutter-like speech in a loop, they still fire up in sync with the tempo.

Real-time
The various voice parameters are applied just before triggering the speech and are ineffective while speaking. They are applied to the next utterance. The best is to fiddle a bit with the knobs for the desired effects.
