ABSTRACT

A new formalism to numerically measure phonetic differences between speech sounds treating feature values of the compared phones as independent parameters that give rise to corresponding Euclidean distances is put forward. The articulatory and acoustic methods within this formalism were compared, where the corresponding results display good agreement. The more reliable and more universal character of the acoustic approach is provided by robust and precise acoustic parameters used therein. The theoretical model and the findings of this article comply also with the experimental phonetic results. The proposed approach contributes to formalization of the procedure of phone comparison and mapping needed for automatic text and speech processing.

摘要

提出了一种新的形式主义，以数值测量语音之间的语音差异，将比较音素的特征值视为产生相应欧几里德距离的独立参数。比较了这种形式主义中的发音方法和声学方法，其中相应的结果显示出良好的一致性。声学方法更可靠和更通用的特性是由其中使用的稳健和精确的声学参数提供的。本文的理论模型和研究结果也符合实验语音结果。所提出的方法有助于自动文本和语音处理所需的电话比较和映射过程的形式化。
