論文名稱:半自動人聲配音系統之研究
論文摘要:

        摘 要

人聲配音或音色轉換就是要將一種原始音色轉換成許多不同的音色。在戲劇作品(如廣播劇)裡的人聲配音工作,通常必須要有許多的配音員,而本研究便是要運用電腦來作音色轉換處理,而達成只需要一位配音員便能夠做到配出許多不同音色的功能,以節省人力、物力,實現個人配音工作室的理想。我們研究的人聲配音系統稱之為半自動的,因為喜怒哀樂的表達仍然要由語音信號的輸入者來控制。

本論文提出了一個音色轉換的方法,就是藉由獨立控制基頻、聲道長度、聲源訊號以及聲道內部比例等方式,來達到改變人聲音色的目標,其中聲道比例控制之因素是新提出來的。我們已建造出此人聲配音系統,在一些限制下可線上即時操作,並且經由實際聽測驗証的確可得到相當豐富的音色轉換。

 

       ABSTRACT

Voice-dubbing or timbre conversion is meant that many distinct timbres can be obtained from a single voice source by conversion processing. In drama works, different actors are usually dubbed with different timbres and many dubbing persons are required. To reduce the cost spended to dub the actors, it will be useful if the computer can help to convert a single voice timbre to many distinct timbres. Therefore, a semiautomatic voice-dubbing (i.e. timbre conversion) system is studied and developed in this thesis. It is called semiautomatic because the emotion (like, anger, sad, happy) perceived from the converted voice will still be controlled by the person who provides the original voice.

In this thesis, a method for timbre conversion is proposed. The goal of timbre conversion is accomplished by providing independent control of fundamental frequency, vocal track length modification, voice source, and internal ratio of vocal track. Among the four factors, the factor of internal ratio of vocal track is newly studied here. As a result of this thesis, a really operable timbre-conversion system is built. It can be used for on-line real-time timbre conversion under some constraints. Also, according to our perception test results, it can indeed convert a single voice timbre to many distinct timbres.
