| 摘 要： | 多通道电子耳蜗产品在安静环境下取得了很好的言语识别效果,然而在混叠语音条件下,使用电子耳蜗患者的言语识别能力快速下降.通过在混叠语音条件下的听觉仿真试验,研究了不同算法对声音信息的传递效果,得出了频率信息对于混叠语音识别效果的重要影响,并借此提出要研究更有效的电子耳蜗语音处理算法.

| Abstract: | The modern multi-channel cochlear implant devices produce good speech recognition scores in quiet. However, the ability of most implant users to understand speech with the speech maskers remains quite poor. The goal of this study is to investigate the effect of spectral details encoding in speech processing on Mandarin recognition based on various acoustic models. The improvement of the strategies that encoded spectral details was observed for speech recognition with speech maskers. We also proposed the implementation methods to improve the strategy and stimulate further investigation. |
