Technology Overview
MUVOC® (MUsic and VOice Core) is a unique and scalable patented technology whose modularity makes it possible to provide user-adapted and progressive voice-processing solutions including coding, noise filtering, word command recognition and transformation.

 

Flexible combination of independent modules makes MUVOC® need only a single core! This assures fast operation even on simple CPUs (ARM, DSP, Intel, PPC...) and makes MUVOC® compatible with most embedded chipsets and operating systems. It also simplifies development and maintenance of the solutions used by Vocally's customers.

 

MUVOC® computes all essential sound parameters in the analysis step, which then can be exploited by subsequent coding/decoding, noise filtering, transformation, and learning/recognition modules, possibly in distributed systems. Vocally has built several independent modules to handle those parameters in a ready-to-use software product family.

 

MUVOC® works with sample rates from 8 000 Hz to 96 000 Hz and with 16 or 24-bit samples.
