A data field approach coupled with binary time-frequency masking is presented for the speech enhancement problem. In this proposed approach, data field method is employed to model the time and frequency dependencies of speech. This formulation has proved to be very helpful in enhancing speech quality by exploiting the correlation of speech both in time and in frequency. The experimental results demonstrate that the proposed algorithm offers improved signal to noise ratio and less spectral distortion.

Do poprawy jakości dźwięku mowy zastosowano metodę pola danych (Data field) połączoną z binarnym maskowanie czasowoczęstotliwościowym. Pozwoliło to znacząco poprawić jakość dźwięku przez wykorzystanie korelacji czasowej i częstotliwościowej. Uzyskano poprawę stosunku sygnału do szumu i zmniejszenie poziomu zniekształceń.
