VoCon® Speech Signal Enhancement (SSE) is a suite of technologies that work together to remove noise from microphone input and send out a cleaner signal. Supporting both single and multiple microphone systems, VoCon® SSE is especially useful in telephone applications where cleaner signals result in a superior user experience. VoCon® SSE’s barge-in and talk-over capabilities allow for more natural user interactions without compromising speech recognition.
Superior Noise Suppression and Better Speech Recognition Performance
- Robust full duplex echo-canceller
(Type 1)
Eliminates trade-off between echo suppression and double-talk performance. - High-quality noise reduction Delivers 10-12 dB noise reduction without significantly impairing speech quality.
- Adaptive microphone self-calibration
Improves robustness against microphone mismatch. - Echo and noise suppression
Improves the microphone signal resulting in more audible telephone conversations and better speech recognition performance. - Scalable ANSI C library
Available for fixed-point and floating-point processors and can be used on nearly every general purpose processor or DSP. | - Wind noise suppression
Improves the microphone signal often impaired by wind noise from climate control fans, open windows or convertible tops. - Beam forming and post-filtering
Improves the microphone signal resulting in more audible telephone conversations and better speech recognition performance. - Generic beam-former implementation
Supports configuration to nearly arbitrary microphone geometries and eliminates tuning efforts. - Quality standards
Supports VDA and ITU standards for qualification of hands-free systems. |
