惠州方言发音的唇位可视技术研究

A Visualization Technology Study on the Lip-position of Huizhou Dialect pronunciation

【目的/意义】传统的方言语音词典或多媒体语料库只能听到方言语音,不能直接观察到发音时人脸器官动态变化的情况,无法获得方言发音的直观视觉印象。本文提出了一种根据惠州方言发音实时展示唇部动态变化的方法。【方法/过程】本文首先标注出唇部的特征点,对发音人发音时唇部特征点变动情况进行记录,通过与普通话发音的对比,将惠州方言发音唇部变化归纳为八种基本唇形。提出通过唇形变化等效字集将惠州方言唇位变化转换为对应的普通话发音唇位变化。在SitePal平台上,利用普通话发音唇位可视功能模拟出惠州方言发音唇位可视效果。【结果/结论】增加唇位可视效果后用户能直接地观察到惠州方言发音时唇位的变化情况,便于用户模仿发音,提高了惠州方言的学习效率,为保护和传承惠州文化提供一种新的技术手段。

Traditional Dialect Voice Dictionary or multimedia corpus can only hear dialect speech but cannot be directly observed situations of dynamic changes of pronunciation in the face,unable to obtain the direct visual impression of dialect pronunciation. This paper presents a method based on Huizhou dialect pronunciationreal-timedisplay of dynamic changes of lip.This paper marks feature points of the lips,recording changes of feature points of speakers' lip and comparing them with Mandarin. Lip position changes of Huizhou dialect pronunciation can be filed into eight basic lip positions. It puts forward that the corresponding lip position changes of Mandarin can be converted from lip position changes of Huizhou dialect pronunciation by lip change equivalent word set. Based on the SitePal platform,the visual effect of the lip position of Huizhou dialect pronunciation is simulated by using the visual function of Mandarin pronunciation.By increasing the visual effect of lip-position,the users directly observe the visual changes of lip position of Huizhou dialect pronunciation. It is convenient for the user to imitate the pronunciation of Huizhou dialect which improves learning efficiency of Huizhou dialect and provides a new technological means for the protection and inheritance of Huizhou culture.
