临床医生通常会要求儿童在干预期间说出最好的言语。然而，目前尚不清楚孩子们是否知道如何回应这些指示，以及他们的表达中的任何偶然变化是否真的会带来更好的言语。对听力正常 (NH) 和人工耳蜗 (CI) 儿童的正常和最佳言语进行了各种声学测量的比较。孩子们（7 至 14 岁）被要求阅读 10 个简单的句子，以训练一个虚构的儿童自动语音识别器。随后，他们用最好的、然后是最好的、最清晰的语音产生了相同的句子（表面上是为了测试识别器）。计算所有句子的句子、停顿和元音持续时间以及元音强度和基频。此外，通过元音空间大小以及浊音和清音塞音之间的发声时间差异来评估语音独特性。 NH 儿童表现出类似于广告的最佳言语模式......
It is common among clinicians to ask children to produce their best speech during intervention. However, it is unclear whether children know how to respond to these directions and whether any contingent changes in their production actually result in better speech. Normal and best speech for children with normal hearing (NH) and cochlear implants (CI) were compared on a variety of acoustic measures. The children (7 to 14 years of age) were asked to read ten simple sentences to train up a fictional automatic speech recognizer for children. They subsequently produced the same sentences with their best and then very best, very clearest speech (ostensibly to test the recognizer). Sentence, pause, and vowel duration were calculated for all sentences as well as vowel intensity and fundamental frequency. Additionally, phonetic distinctiveness was evaluated through vowel space size and voice onset time differences between voiced and voiceless stops. NH children demonstrated patterns of best speech that resemble ad...
