项目摘要

Speech disorders caused by oral and maxillofacial lesions are diagnosed by clinicians based on subjective evaluation using auditive impression. The purpose of this research is developing the computerized diagnosis system for the subjective evaluation of articulation disorders.From 2005 to 2006 the results of MR and Acoustic results in velopharyngeal incompetence patients and glossectomee and normal children were obtained.To clarify the relationship between the perceptual diagnoses of hypernasality and its physical correlates experiments were conducted using Japanese vowel /i/. As results the decrease in the magnitude of F2 and the dip between F2 and F3 are related to excessive acoustic coupling of the nasal cavity (Kozaki 2005). The acoustic characteristics of children of the Japanese consonants [s][sh], especially focused on the stage of missing deciduous incisors were clarified (Sugiyama 2006). The vocal tract shapes are measured and the VTTF of vocal tract model are estimated, in order to investigate effects of vocal tract shapes on the spectrum of speech sound. As a result vocal tract shapes having oral lesions are different from normal one (Nishimoto 2006). Finally we tried the estimation of movements after Glossectomy based on 3D physiological tongue model and the simulations proved that developed model can be a useful tool for the study of speech disorders with pathology of the tongue (Fujita 2007)

临床医生通过使用听觉印象的主观评估来诊断由口腔和颌面病变引起的语音障碍。这项研究的目的是开发用于关节疾病的主观评估的计算机化诊断系统。从2005年到2006年，获得了MR和声学的结果在静脉咽喉无能的患者以及正常儿童和正常儿童的结果中。阐明了超然学诊断的感知性诊断与其物理校正性实验的相关关系。结果，F2和F2之间的幅度下降与鼻腔的过度声音耦合有关（Kozaki 2005）。阐明了日本辅音儿童的声学特征[S] [SH]，尤其是专注于缺少落叶牙齿的阶段的声学特征（Sugiyama 2006）。测量声带形状，并估算声道模型的VTTF，以研究声音形状对语音频谱的影响。结果，口腔病变的声带形状与正常损伤不同（Nishimoto 2006）。最后，我们尝试了基于3D生理舌模型的格式切除术后运动后的运动估算，并且模拟证明开发的模型可以成为研究舌头病理学言语疾病的有用工具（Fujita 2007）
