소음저감 기술 : NS (Noise Suppressor)


   ■ NS technology…

   ▶ Estimate noise floor in frequency-domain with fast noise tracking

   ▶ Additive algorithm for low musical noise, low voice distortion and naturalness

       of residual noise

   ▶ 2 mic beamforming for clearer voice pick-up


   ▶ Maximum 26dB SNR enhancement with dual microphone.

   Voice activity detection with real-time speech modeling, reduce residual voice

      distortion or musical noise even at low SNR.

   ASR recognition rate recovery about 50%

       ex) If recognition is 60% without NS, recognition is about 80% with NS
