摘要目的口腔修复术中，由于修复体影响患者语音的可懂度，因此需要对患者语音进行客观的评估。嗓音起始时间的测量是语音学中评价辅音产生的一种方法。本研究的目的是确认的腭假体上的辅音生产的影响，通过测量语音onset time.Materials和MethodsIn这项研究中，语音onset时间测定在10名健康女性（平均年龄26.5岁）在两种条件下：有和没有实验腭假体。本研究以/ta/和/ka/的发声起始时间来确定佩戴腭部假体的效果;以/pa/为对照，零假设为/ta/和/ka/的发声起始时间在佩戴腭部假体时不会改变。实验组与对照组相比，/ta/和/ka/的发声时间延长，而/pa/的发声时间无显著性差异。结论腭部假体对辅音的产生有影响，并且通过测量声音起始时间来检测声音的这种变化。
PurposeObjective evaluation of a patient's speech is needed in prosthetic dentistry because the prostheses can affect the intelligibility of speech. Measurement of voice onset time is one evaluation method of consonant production used in phonetic science. The purpose of this study was to confirm the influence of a palatal prosthesis on consonant production by measuring voice onset time.Materials and MethodsIn this study, voice onset time was measured in 10 healthy women (mean age 26.5 years) under two conditions: with and without an experimental palatal prosthesis. In this study, voice onset time of /ta/ and /ka/ were used to determine the effect of wearing a palatal prosthesis; /pa/ was tested as a control, with the null hypothesis that voice onset time of /ta/ and /ka/ would not change when wearing a palatal prosthesis.ResultsMedial voice onset time of /pa/, /ta/, and /ka/ syllables without the palatal prosthesis was 22.5 ms, 19.5 ms, and 42.5 ms, whereas that with the palatal prosthesis was 22.5 ms, 23.5 ms, and 55.0 ms. Voice onset times for /ta/ and /ka/ were prolonged when wearing the experimental palatal prosthesis, whereas /pa/ showed no significant difference.ConclusionConsonant production was affected by wearing a palatal prosthesis, and this change in sound was detected by measuring voice onset time.
