Abstract

A new speech processing strategy (SPEAK) has been compared with the previous Multipeak (MPEAK) strategy in a study with 24 postlinguistically deafened adults. The results show that performance with the SPEAK coding strategy was significantly better for 58.31% of subjects on closed-set consonant identification, for 33.3% of subjects on closed-set vowel identification and open-set monosyllabic word recognition, and for 81.8% of subjects on open-set sentence recognition in quiet and in competing noise (+ 10 dB signal-to-noise ratio). By far the largest improvement observed was for sentence recognition in noise, with the mean score across subjects for the SPEAK strategy twice that obtained with MPEAK.

摘要

在一项针对24名语后聋成年人的研究中，一种新的言语处理策略（SPEAK）与之前的多峰（MPEAK）策略进行了比较。结果显示，对于58.31%的受试者，在闭集辅音识别方面，SPEAK编码策略的表现显著更好；对于33.3%的受试者，在闭集元音识别和开集单音节词识别方面表现更好；对于81.8%的受试者，在安静环境以及有竞争噪声（信噪比为+10 dB）的开集句子识别方面表现更好。到目前为止，观察到的最大改进是在噪声环境下的句子识别，采用SPEAK策略的受试者平均得分是采用MPEAK策略时的两倍。
