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.
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。
