摘要

由于语音转换的众多应用,包括配音、文本到语音合成和多媒体,语音转换是当今主要研究兴趣的主题。音高转换是实现高效语音转换的重要组成部分。本文重点研究了基音缩放和基音转换的实现。有效的静音去除、声音/非声音检测、音调提取、音调标记和PSOLA技术已经实现了用于音调缩放,以及用于音调转换的音调标记映射方法的实现。已经开发了一个图形用户界面,用于评估和说明目的。对各种语音数据进行了基音缩放和基音转换技术的评价。利用变换后语音的音高轮廓图,实现了男女说话人的音高缩放和音高转换,并进行了验证。

Pitch conversion based on pitch mark mapping
Voice conversion is a subject of major research interest these days, due to its numerous applications including dubbing, text to speech synthesis and multimedia. Pitch conversion is an important building block for efficient voice conversion. This paper focuses on the implementation of pitch scaling and pitch conversion. Effective silence removal, voice/unvoiced detection, pitch extraction, pitch marking and PSOLA techniques have been implemented for pitch scaling along with an implementation of pitch mark mapping method for pitch conversion. A graphical user interface has been developed for evaluation and illustration purposes. Evaluation of the pitch scaling and pitch conversion technique was performed on various speech data. Pitch scaling and pitch conversion for both the male and female speakers was implemented and verified with the help of pitch contour plots of the transformed speech.
