Time-compressed speech test: adaptation and validation

ABSTRACT Purpose: to adapt the Time-Compressed Speech Test and verify the applicability of the new test, correlating it with the original. Methods: the adaptation of Time-Compressed Speech Test was possible through the criterion of phonetic balance. It was used an editing software called Free Audio Editor to cut the words from the original test and generate the new file. From fifty words already presented in the original test, twenty-five were preserved in the new test. For the validation, were evaluated 73 subjects aged from 16 to 30 years-old, who performed the procedures of Hearing Anamnesis and of Auditory Processing, Visual Inspection of the External Acoustic Canal, Pure Tone Audiometry, Speech Audiometry, Acoustic Immittance Measurement, Diotic Testing, original Time-Compressed Speech Test and adapted Time-Compressed Speech Test. Results: a new list of 25 two-syllable words was created. There were differences between the number of errors and the percentages of correct answers by ear, between the original and the adapted Time-Compressed Speech Test. The strength correlation between the tests was moderate, thus the reference values of the original test could not be used in the adapted instrument. Conclusion: it was possible to adapt the Time-Compressed Speech Test observing a moderate correlation between both tests and verify the applicability of the Adapted Time-Compressed Speech Test. Therefore, the adapted test needs new reference values, in other words, normality criteria are required.摘要 研究目的：对时间压缩言语测试（Time-Compressed Speech Test）进行改编，验证该新版测试的适用性，并探讨其与原版测试的相关性。 研究方法：本研究通过语音平衡准则完成时间压缩言语测试的改编，使用Free Audio Editor音频编辑软件从原版测试中截取词汇并生成新版测试文件。原版测试共包含50个词汇，新版测试保留其中25个。为验证改编效果，共招募73名年龄介于16至30岁的受试者，依次完成听力病史采集、听觉处理评估、外耳道视诊、纯音测听、言语测听、声导抗测试、双耳听觉测试、原版时间压缩言语测试以及改编版时间压缩言语测试。 研究结果：本研究构建了包含25个双音节词的新版测试词表。原版与改编版时间压缩言语测试在耳测错误数及正确答题百分比上均存在差异；两项测试的相关强度为中等程度，因此原版测试的参考值无法直接应用于改编版测试工具。 研究结论：本研究成功完成时间压缩言语测试的改编，且两款测试间呈中等程度相关，验证了改编版时间压缩言语测试的适用性。但该改编版测试需建立新的参考值，换言之，需制定专属常模标准。
