Hands-free Communication in Full-Duplex Quality and with Innovative AEC

vicHSES - Handsfree and Speech Enhancement Suite.

The signal processing library vicHSES provides an excellent, full-duplex speech quality for hands-free systems. Patented methods for acoustic echo cancellation (AEC) adapt to environmental conditions continuously and eliminate disturbing echos automatically. Further efficient signal processing algorithms enable an optimal adaptation to channel conditions, device features, adequate loudness and high speech intelligibility.
