Speektra – Retro Chipspeak Synthesizer

PureMagnetik recently released Speektra, “a speech simulation synthesizer based on the VOSIM method developed by Kaegi and Tempelaars in the 1970s. It uses bursts of pulses with formant characteristics to synthesize robotic vowel sounds.” VOSIM stands for Voice Simulation and 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 according to the Journal of the Audio Engineering Society, June, 1978. 

The user interface is very clean and quite easy to get started with right away. The controls are simply allowing for synthesis shaping through Attack, Decay, Sustain and Release. We are also given a knob for each vocal wave. Puremagnetik implements VOSIM in a more elaborate way by allowing you to modulate the shapes of your sounds between vowels and waveshapes. You can also choose your voice register (Bass to Soprano). Speektra will make an excellent lead voice synth, it’s great for creating percussive vocal chops, or a choral drone. Below is a list of features.

• 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
• Includes a collection of factory presets

Minimum Requirements
• OSX 10.8 or Windows 10 x64
• Audio Units or VST compatible audio host
