VoCon® Speech Signal Enhancement (SSE)

A Cleaner Signal for Superior Performance

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.
