title: [Study on the effect of spectral details encoding in speech processing on Mandarin recognition for cochlear implants users with speech maskers].
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.
