【摘要】：目的探讨不同性别、文本材料、母语方言对普通话长时平均言语频谱图(long-term average speech spectrum,LTASS)的影响,为LTASS应用于临床听力学及科研提供参考。方法选择官话、吴话、湘语、赣语、客家话、闽北话、闽南话及粤语8大方言区的160例受试者,各方言地区10男10女,年龄16~30岁,平均22.3±3.25岁,每例受试者按要求在标准隔声室内用平稳语速与音量的普通话通过BK(4192)麦克风朗读语音材料(包括新闻和小说两类),由实时频谱分析仪(BK PULSE3560C)提取所需要的频率和强度并作记录,绘制出普通话LTASS并统计分析其在不同性别、文本材料及母语方言之间的差异。结果绘制得到普通话LTASS图,进行轮廓分析(α=0.05),语言材料对LTASS无影响,差异无统计学意义(F=2.52,P=0.11);性别(F=116.39,P=0.00)、母语方言(F=1.29,P=0.02)对LTASS有影响,男性在100、125、160、200Hz频率发音强度高于女性,粤语区普通话LTASS整体输出强度低于其他方言普通话。结论普通话LTASS应用于临床及科研中需要考虑性别和不同地域因素的影响。
[Abstract]:Objective to explore the effects of gender, text materials and native dialects on the long term average speech spectrum (long-term average speech spectrum,LTASS) of Putonghua in order to provide reference for the application of LTASS in clinical audiology and scientific research. Methods one hundred and sixty subjects from 8 major dialect areas, including Mandarin, Wu, Xiang, Gan, Hakka, Minbei, Minnan and Cantonese, were selected. There were 10 males and 10 females in each dialect area, with an average age of 22.3 卤3.25 years old. Each subject was asked to read speech materials (including news and fiction) through a BK (4192) microphone in a standard soundproof room at a steady pace and volume in Mandarin. The required frequency and intensity were extracted and recorded by real-time spectrum analyzer (BK PULSE3560C). The LTASS of Putonghua was drawn and the differences among different gender, text materials and native dialects were analyzed statistically. Results the LTASS map of Putonghua was drawn and the contour analysis was carried out (伪 = 0. 05). The language material had no effect on LTASS, but the difference was not statistically significant (F2. 52% P0. 11). Gender (F _ (116.39) and native dialect (F _ (1.29) / P _ (0.02) had an effect on LTASS. The intensity of pronunciation in 100125160200Hz of male was higher than that of female, and the output intensity of LTASS in Cantonese was lower than that in other dialects. Conclusion in clinical and scientific research, the influence of gender and different geographical factors should be taken into account in the application of Putonghua LTASS.
