Puremagnetik has announced the release of a new speech simulation synthesizer based on the VOSIM method developed by Kaegi and Tempelaars in the 1970s.
Speektra uses bursts of pulses with formant characteristics to synthesize robotic vowel sounds.
VOSIM (VOice SIMulation) sound synthesis is based on the idea that by employing repeating tone-burst signals of variable pulse duration and variable delay, a sound output of high linguistic and musical expressive power can be obtained. – Journal of the Audio Engineering Society, June, 1978
The Puremagnetik implementation of VOSIM stretches things a bit further, allowing you to seamlessly morph between vowels, manually or via a modulator. You can also choose your voice register (Bass to Soprano). Designed with a versatile set of controls, Speektra excels as a lead voice synth, a percussive vocal, or a choral drone.
- VOSIM-based vocal synthesis.
- Manual or modulated control of vocal morph functions.
- Random function for inter-note modulations.
- Voice register selection.
- Integrates into any VST / Audio Units compatible host.

Speektra for Windows and Mac is currently offered as part of Puremagnetik’s Spark subscription for $8 USD per month. After one month it will become back-cataloged for a la carte purchase at $20 USD.
