| Abstract(in English) | This work presents a hybrid approach for enhancing the quality of the electrolaryngeal (EL) speech. Current hybrid enhancement systems rely on noise suppression and statistical voice conversion techniques. However, utilizing a vocoder to generate the converted waveform usually degrades the quality of the converted speech. To alleviate the quality degradation caused by the vocoder, we proposed a vocoder-free enhancement method based on direct modification of the waveform using differences in spectral features of the EL and normal speeches. After applying a time-variant filter to the EL speech for enhancing its quality, noise suppression is further applied to the enhanced EL speech to reduce remaining time-varying noise components. To evaluate the effectiveness of our proposed method, subjective evaluations based on an opinion test on intelligibility has been performed. Our experimental results show that the proposed method improves intelligibility of the EL speech. |
