摘要
基频微扰(jitter)和振幅微扰(shimmer)分别体现声带振动的不规律性和不稳定性,是衡量嗓音特征的重要参数。本文通过提取40个汉语方言点常用词汇录音的jitter和shimmer数据,统计分析经纬度、地理方位的南北、湿度、性别、海拔等6个影响因素对其的影响,看到湿度、纬度对jitter和shimmer的影响较为重要,同时二者还受到性别的影响。就40个方言点而言,海拔不是影响jitter和shimmer的因素。湿度、纬度、性别等对正态化后的jitter和shimmer变异的预测分别可达10.6%和8.4%。干燥、地理位置上更靠近北方的方言点,jitter和shimmer都更高,声带振动越不规律、不稳定,同时,女性的嗓音表现更稳定、规律。
Jitter and shimmer refer to the irregular small cycle-to-cycle variations in frequency and amplitude during voiced regions of speech.They are important measures of voice quality.In this study,these two parameters were extracted from recordings of common expressions in 40 Chinese dialects for statistical analysis.The paper is concerned with how jitter and shimmer are correlated with environmental factors such as longitude,latitude,altitude,geographical zones(North and South),and humidity.The finding shows that humidity and latitude have great effects on jitter and shimmer,and gender also affects the voice quality.Humidity,latitude and gender could indicate 10.8%of the variance in jitter and 8.4%of the variance in shimmer after normalizing the voice quality data.Results further show that jitter and shimmer are higher in dialectal zones in the North and drier climate,where people's vocal folds vibrate more irregularly and less precisely.And the voice quality of females is more stable and regular.Furthermore,altitude is not likely a factor showing significant impact on jitter and shimmer.
