MUVOC Noise Filter combines MUVOC Core Analysis and an adaptive filter. This solution attenuates the ambient noise and enhances the voice clarity and intelligibility, and thereby improves the listening conditions.
It preserves the naturalness of the original voice without deforming it even for high-level ambient noise.
MUVOC Noise Filter needs only one channel (a single microphone).
The speech quality after applying the noise filter is quantified in the figure to the right based on the PESQ standard (Perceptual Evaluation of Speech Quality). The quality is expressed in MOS (Mean Opinion Score). The same performance gain has been obtained using STT (Speech To Text) combined with the Noise Filter.
noise filtering DURING mobile phone conversation.The noise filter is enabled in the middle of the call.

Turnkey solution example for entry phone
The Noise Filter is ideal for the entry phone. It reduces even strong ambient noise and renders the voice clear and intelligible.
