【摘要】：目的:从语音知觉角度出发初步探究感音神经性聋患者的汉语普通话声调知觉的心理物理学特征知觉模式特点及其与听力正常人的异同。方法:采用POSOLA信号合成技术对普通话女发声人的原始语音材料/ā/的基频进行控制,获得基频曲拱连续变化的一声/二声(T1/T2)、一声/四声(T1/T4)和二声/三声(T2/T3)的3组声调连续统。并在E-Studio测试平台控制下对23例感音神经性聋患者进行识别任务测试。采用SPSS 19.0软件拟合感音神经性聋患者声调知觉曲线,分析其声调知觉模式特点及其与听力正常人的异同,探究引起差异的可能原因。结果:①感音神经性聋患者声调知觉曲线具有明确的曲线边界和交点,在曲线交点前后测试成绩发生突变,符合范畴化知觉特性;其曲线形态呈现倒"S"型,与听力正常组类同;②该组耳聋患者声调连续刺激声的反应率与听力正常人无明显差异(T1/T2组∶P=0.811;T1/T4组∶P=0.528;T2/T3组∶P=0.555)。结论:感音神经性聋患者汉语普通话声调知觉模式仍可表现出范畴知觉特征,听觉系统的轻度受损对声调知觉模式的影响程度有限。
[Abstract]:Objective: to explore the psychophysical characteristics of tone perception in Chinese mandarin in patients with sensorineural hearing loss from the perspective of phonological perception. Methods: POSOLA signal synthesis technique was used to control the fundamental frequency of the original speech material / of the female speaker of Putonghua, and the continuous change of the fundamental frequency of the first / second tone (T1/T2) was obtained. One / four (T1/T4) and two / three (T2/T3) three groups of tone continuum. The identification task of 23 patients with sensorineural hearing loss was tested under the control of E-Studio test platform. The tone perception curve of sensorineural deafness patients was fitted with SPSS 19.0 software. The characteristics of tone perception patterns and their similarities and differences with normal hearing were analyzed, and the possible causes of the differences were explored. Results: 1 the tone perception curve of sensorineural deafness patients had definite curve boundary and intersection point. (2) the response rate of continuous tone stimulation in this group was not significantly different from that in normal hearing group (T1/T2 group: P < 0.811T _ 1 / T _ 4: P ~ (0.528); T2/T3 group: Pu 0.555). Conclusion: the pattern of tone perception in Chinese mandarin can still show the characteristics of category perception in patients with sensorineural deafness, and the degree of influence of slight impairment of auditory system on tone perception pattern is limited.
