言语编码策略升级对成年人工耳蜗使用者听觉效果影响的研究
Effect of speech recognition outcomes in mandarin-speaking cochlear implant users with updated speech coding strategy
摘要
Abstract
OBJECTIVE To determine speech perception,tone perception and the subjective preferences of mandarin-speaking adults who received the fine structure processing(FSP) coding strategy,at upgrade from the continuous interleaved sampling(CIS+) coding strategy.METHODS Thirteen mandarin-speaking subjects were tested at switch-over from CIS+ to FSP coding strategy approximately 1-,2-,and 3-month after switch-over with the mandarin hearing in noise test(M-HINT),the mandarin tone identification in noise test(M-TINT),and a visual analogue scale assessing sound and speech assessment(SSA).RESULTS Tone perception improved significantly over time with the FSP coding strategy.There were no significant differences in the MHINT over time,nor when compared to the CIS+ coding strategy.Subjects rated the FSP coding strategy with the OPUS 2 as significantly more "full" and "rich" than with the CIS+ coding strategy after 3-months.CONCLUSION Mandarin-speaking adults can use the FSP coding strategy as well as CIS+ coding strategy.Loss in performance was not observed after switch-over.Tone identification improves over time with the FSP coding strategy,which is beneficial to tonal-language users.关键词
