Hands-free and Speech Enhancement Suite

vicPURE handsfree.

The vicPURE handsfree signal processing library provides excellent full-duplex speech quality for hands-free equipment.
Key component of the suite are acoustic echo cancellation techniques that continuously adapt to the acoustic environment and automatically eliminate unwanted echos.
Other powerful signal processing algorithms ensure high speech intelligibility, appropriate volume and optimum adaptation to transmission channel conditions or various device characteristics. The patented algorithms meet the highest standards and can be customised to your application.
