A Chinese speech compensation method for the leakage based on generalized sidelobe canceller in hearing aids

In this paper, the leak of speech caused by generalized sidelobe canceller beamformer algorithm is analyzed from the view of Chinese. A Chinese speech processing technology is proposed to compensate the leak of speech. Amplitude spectrum envelope was modified to improve the similarity between spectrum envelope and the pitch contour with the information of pitch contour. Considering that the speech signal has a great loss in the high frequency range, as a characteristic of the leak information, a consonant amplification method could raising the energy of voiceless consonant, reducing the energy section of the noise and improve speech intelligibility without changing the formant structure. The results show that the signal after the algorithm treatment improved the intelligibility of speech.
