Humankind can express their emotions, such as happiness, sorrow, anger, and etc., by singing a song. Unfortunately, to our knowledge, pertinent reasearches on this competency such as synthesizing voice signal are not common. Here, we investigated the nature of timbre and tried to computerize the process of human singing. This thesis is a summary of our studies on how to analyze and synthesize voice signal. We will elaborate on explaining how the human voice is parameterized by notation, characteristic, and voice parameters and how an intact voice can be retrived via these parameters. This thesis refers to the master thesis of Wan-Chin Ou. The program is from NSC 93-2213-E-002-081, and modified by Zhi-Ying Peng. The new contribution of this work is the Wigner-Ville Distribution upon which we have some preliminary results.1 Introduction 6 2 Analysis 8 2.1 Estimation of the Notation Parameters 8 2.2 Generation of the Characteristic Parameters 9 2.2.1 Extraction of the Fundamental Frequency and Vibrato Properties 10 2.2.2 Extraction of the Amplitude 11 2.3 Generation of the Voice Parameters 11 2.3.1 Voiced Analysis Point 13 2.3.2 Unvoiced Analysis Point 14 2.3.3 Peak Matching 14 2.4 Wigner-Ville Distribution 19 3 Synthesis 25 3.1 Manipulative Synthesis 25 3.1.1 Generation of the Control Table 25 3.1.2 Produce the Synthesized Singing Voice 26 3.2 Sinusoidal Synthesis 30 3.3 Sound Unit Synthesis 33 3.3.1 The Querying Strategy 33 3.4 Smoothing 34 3.4.1 Smoothing for Sinusoidal Synthesis 35 3.4.2 Smoothing for Sound Unit Synthesis 35 4 Demonstration 38 4.1 Preparation 38 4.2 Analyze the Sound Unit 39 4.3 Produce the Synthesized Song 42 5 Conclusion 431655561 bytesapplication/pdfen-US合成音色訊號維勒分布the synthesis of voice signalwigner-ville distributionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/53782/1/ntu-94-R92922070-1.pdf
