项目摘要

【Purpose】 We investigated the perceptual weighting of syllable-initial fricatives for native Japanese adults and for children with persistent developmental articulation disorder to elucidate the mechanism behind the disorder and to identify an effective treatment.【Method】 Forty-two native Japanese adults and 2 native Japanese children with developmental phonological disorder identified tokens from a /∫/ - /s/ continuum followed by /α/ as /∫α/ or /sα/. Stimuli consisted of natural /s/ and /∫/ noises combined with synthetic /α/ vocalic portions. In order to create the consonant portion, /s/ and /∫/ were separated from /∫α/ and /sα/ syllables recorded by a native Japanese male speaker. These spectra of fricative noises were varied along a nine-step continuum, from one appropriate for /∫/ to one appropriate for /s/. Nine synthetic vocalic portions were created using XKL Klatt, 1984) to form a nine-step continuum, varying in formant transitions changing continuously from one most like /∫/ to one most like /s/.【Results & Discussion】 Most adults weighted to the spectrum of the fricative noise more than to formant transitions in the same manner as English native adults, however, as compared with most adults, a small number of adults and the children with persistent developmental articulation disorder judged based more on the formant transitions than on the spectrum of the fricative noise like 3- to 4-year-old typically developing English native children (Nittrouer & Miller, 1997).【Conclusion】 The perceptual weight assigned by adults suggested that they did not perceive uniformly. The perceptual weight assigned by children with developmental phonological disorder indicated that their speech perception ability might develop differently from that of typically developing children because of speech processing deficits.

[目的]研究持续性发展性构音障碍患者和日本本土成人的音节首摩擦音的感知权重，以阐明该障碍背后的机制并确定有效的治疗方法。[方法] 42名日本本土成年人和2名日本本土发育性语音障碍儿童从a //- /s/连续体中识别出/α/ as /α/或/sα/。刺激由自然/s/和/sb/噪声与合成/α/元音部分组合而成。为了创建辅音部分，/s/和//从一位日本男性母语者记录的/α/和/sα/音节中分离出来。这些摩擦音的频谱沿着一个九步连续体变化，从一个适合于/s/到一个适合于/s/。使用XKL Klatt（1984）创建了九个合成元音部分，以形成九个步骤的连续体，共振峰过渡从一个最像/s/到一个最像/s/连续变化。[结果与讨论]大多数成年人与英语母语成年人一样，对摩擦音频谱的权重大于共振峰转换，然而，与大多数成年人相比，少数成年人和持续性发展性构音障碍的儿童更多地根据共振峰转换而不是摩擦音频谱来判断，如3- 4岁，典型发育中的英国本土儿童（Nittrouer &米勒，1997）。[结论]成年人的知觉权重分配不一致。发展性语音障碍儿童的知觉权重表明，由于言语加工缺陷，他们的言语知觉能力可能与正常儿童的发展不同。
