摘要

语音工程中疑问句基频的生成有赖于对疑问句语调走势的全局把握与量化建模。该文以疑问句和陈述句的音高曲线的回归线代表语调走势,结合实验语料和自然语料对二者语调进行分析。发现音高曲线的回归斜率是区别陈述句与疑问句语调的重要韵律特征,该特征受句子长度、时域范围等因素影响,在2种句型中有不同的表现。用反函数对疑问句语调斜率的变化规则进行建模,取得了较高的拟合优度,为疑问句语调走势的预测与生成提供了可靠依据。

Abstract

The identification of questions in speech needs a good understanding and accurate quantification of the intonation trends of questions. This paper uses a regression line of the pitch contour as an indicator of the intonation trend to analyze the intonation of experimental and natural questions. The slope of pitch contour regression line is an important prosodic feature for distinguishing questions from statements. This feature is influenced by factors such as sentence length and temporal domain of the sentence and differs for questions and statements. The inverse was then used to model changes of the intonation trend slope with a high goodness of fit as a reliable reference to predict and generate interrogative intonation.
