The purpose of this study was to investigate the effect of production time on the perception of disordered nasalization in children with cleft palate. The subjects with cleft palate included 5 who produced acceptable speech consistently, 5 who produced disordered nasalization consistently, and 10 who were inconsistent in the production of disordered nasalization. We examined a range of production times similar to those for the production of single-word and connected speech tasks. Ten judges used direct magnitude estimation to rate severity of disordered nasalization. An accelerometric ratio technique was used to estimate the extent and timing of nasal acoustic activity. The results showed that reducing the production time did not change perceptible nasalization.
本研究的目的是调查发声时间对腭裂儿童鼻音化异常感知的影响。腭裂受试者包括5名始终能发出可接受语音的儿童、5名始终存在鼻音化异常的儿童以及10名鼻音化异常发声情况不一致的儿童。我们研究了一系列与单字和连贯语音任务发声时间相似的发声时间。十名评判员使用直接数量估计法对鼻音化异常的严重程度进行评分。采用加速度计比率技术来估计鼻腔声学活动的程度和时间。结果表明，缩短发声时间并不会改变可感知的鼻音化。
