目的:以语音知觉为着眼点探讨听力正常者汉语普通话声调知觉的心理物理学特征。方法:采用PSOLA信号合成技术对普通话女发声人的原始语音材料/ā/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,在E-Studio测试平台控制下对40例母语为汉语普通话的听力正常人进行识别任务测试。采用SPSS 19.0软件拟合汉语普通话听力正常人声调知觉曲线、分析声调知觉模式特性。结果:1听力正常人汉语普通话声调知觉曲线呈现倒“S”型;2声调感知曲线具有陡峭的上升或者下降趋势以及明显的范畴边界;3声调感知曲线内部均具有明确的交点,且交点位置处声调识别成绩出现突变。结论:听力正常人汉语普通话声调知觉模式具有典型范畴知觉特点。
Objective: To explore the psychophysical characteristics of Mandarin Chinese tone perception in normal hearing students from the perspective of speech perception. Methods: The PSOLA signal synthesis technique was used to control the original voice material of Mandarin speakers and to obtain continuous T1 / T2, T1 / T4 and Two sets of Tone / Three Tone (T2 / T3) three sets of tone continuum were used to test the recognition task of 40 hearing-impaired native speakers of Mandarin Chinese under the control of E-Studio test platform. SPSS 19.0 software was used to fit the tone perception curve of Mandarin Chinese speakers, and the characteristics of tone perception pattern were analyzed. Results: (1) The perceived curve of Chinese Mandarin in normal people showed “S” shape. The 2-tone curve showed steep ascending or descending trend as well as obvious category boundary. The three tone curves had clear intersections and the intersections There was a sudden change in tonal recognition scores at the location. Conclusion: Mandarin Chinese tone perception patterns of normal hearing people have typical category perceptual characteristics.
