This study investigated the effect of speech rate for Italian-speaking cochlear implant (CI) users with the aim of gaining insight into everyday listening situations where speaker's rate may vary considerably together with speech level in fluctuating background noise. The test material was prepared by processing the Italian STARR test with temporal compression of sentence material. Twelve adult CI users were divided into two subgroups based on their STARR performance: good and poor performers. The effect of varying speech rate was remarkable for both subgroups. Good performers showed significant performance deterioration for the faster speech rate, whereas outcomes for poor performers improved significantly for the slower speech rate. Background noise is inevitable during daily life and CI users face a variety of speakers, so must cope with changes in both speech level and rate. Traditional tests with a single talker speaking very clearly while using a moderate to low speech rate may overestimate everyday speech perception for CI users. The use of tests that mimic everyday perception is of great importance and should become a routine part of audiometric measures for hearing impaired people.
本研究调查了语速对意大利语使用者人工耳蜗（CI）的影响，目的是深入了解日常聆听情境，在这种情境中，说话者的语速可能会随着语音水平的变化而在波动的背景噪声中大幅变化。测试材料是通过对意大利语STARR测试的句子材料进行时间压缩来准备的。12名成年人工耳蜗使用者根据他们的STARR测试表现被分为两个亚组：表现良好者和表现不佳者。语速变化对两个亚组的影响都很显著。表现良好者在语速较快时表现出明显的性能下降，而表现不佳者在语速较慢时的结果则显著改善。日常生活中背景噪声不可避免，人工耳蜗使用者会遇到各种各样的说话者，因此必须应对语音水平和语速的变化。传统测试中，单个说话者以适中到较慢的语速清晰讲话，这可能会高估人工耳蜗使用者的日常语音感知能力。使用模拟日常感知的测试非常重要，应该成为听力受损者听力测试措施的常规组成部分。
