This paper proposes a speech enhancement method based on active noise control (ANC) theory. Conventional ANC systems remove an observed signal, even if it includes a desired speech signal. To extract the desired speech signal, we introduce a speech reduction method as pre-processing of the ANC system. In this case, the ANC produce only the noise replica, since the input signal to the ANC does not include the speech signal. The speech reduction is achieved by subtracting an enhanced speech from the observed signal, where we use a spectral gain method to obtain the enhanced speech. Since the spectral gain method based on the FFT provides a delay depending on the analysis frame length, we replace the FFT with an inverse notch filter (INF) which is a narrow band-pass filter. Simulation results show that the proposed ANC system with INF is effective to extract the speech signal included in the observed signal. |
