Abstract

Background: Recently, a new speech coding strategy named 'fine structure processing' (FSP) has been launched.

Methods: 32 subjects, all users of the MED-EL PULSARCI(100) system, have been switched over from a TEMPO+ to an OPUS 2 speech processor. In 22 subjects, the FSP strategy could be implemented (FSP group), in 10 patients not (high-definition continuous interleaved sampling, HDCIS, group). Subjects were tested with the Tempo+ (CIS+) just before switch-over and after 12 months of OPUS 2 (FSP/HDCIS) use. Performance with FSP/HDCIS was tested at switch-over, and after 1, 3, 6 and 12 months. A sentence-in-noise test and a Speech Spatial and Qualities of Hearing Scale (SSQ) questionnaire were assessed at each test interval.

Results: In the FSP group, the speech reception threshold shows a deterioration of 3.3 dB (n.s.) at the acute switch-over interval, but a significant improvement over time (p < 0.001) with a final benefit of 6.5 dB after 12 months of FSP use. A significant improvement over time can also be seen on the spatial subscore of the SSQ questionnaire (p = 0.009). No significant differences could be seen in the HDCIS group.

Conclusion: The results show that by enhancing fine structure coding in the lower frequencies, as implemented in the FSP coding strategy, speech perception in noise can be enhanced.

采用精细结构处理编码策略,在噪声环境下具有较好的语音识别效果。
背景:近年来,人们提出了一种新的语音编码策略——精细结构处理(FSP)。方法:32名受试者均使用MED-EL PULSARCI(100)系统,从TEMPO+切换到OPUS 2语音处理器。22例患者可以实施FSP策略(FSP组),10例患者不能(高清连续交错采样,HDCIS组)。在切换之前和使用OPUS 2 (FSP/HDCIS) 12个月后,对受试者进行Tempo+ (CIS+)测试。FSP/HDCIS在切换时以及1、3、6和12个月后测试性能。在每个测试间隔对句子噪声测试和语音空间与听力质量量表(SSQ)问卷进行评估。结果:在FSP组中,语音接收阈值在急性切换间隔下降3.3 dB (n.s),但随着时间的推移有显著改善(p < 0.001),使用FSP 12个月后最终受益6.5 dB。随着时间的推移,SSQ问卷的空间分值也有显著改善(p = 0.009)。HDCIS组无明显差异。结论:FSP编码策略通过增强低频的精细结构编码,可以增强噪声环境下的语音感知。
