情感语音合成是情感计算和语音信号处理研究的热点之一，进行准确的语音情感分析是合成高质量情感语音的前提。文中采用PAD情感模型作为情感分析量化模型，对情感语料库中的语音进行情感分析和聚类，获得各情感PAD参数模型。由HMM语音合成系统合成的情感语音，通过PAD模型进行参数修正，使得合成语音的情感参数更加准确，从而提高情感语音合成的质量。实验表明该方法能较好地提高合成语音的自然度和情感清晰度，在同性别不同说话人中也能达到较好的性能。
情感語音閤成是情感計算和語音信號處理研究的熱點之一，進行準確的語音情感分析是閤成高質量情感語音的前提。文中採用PAD情感模型作為情感分析量化模型，對情感語料庫中的語音進行情感分析和聚類，穫得各情感PAD參數模型。由HMM語音閤成繫統閤成的情感語音，通過PAD模型進行參數脩正，使得閤成語音的情感參數更加準確，從而提高情感語音閤成的質量。實驗錶明該方法能較好地提高閤成語音的自然度和情感清晰度，在同性彆不同說話人中也能達到較好的性能。

Emotional speech synthesis is the emphasis and hotspot in affective computing and speech signal processing. In speech synthesis, accurate speech emotion analysis is a prerequisite for high-quality synthesis of emotional speech. In this paper, PAD emotional model is used to build a 3D emotional space for sentiment analysis and clustering of emotional corpus of speech in order to get emotional PAD parameters model. The emotional speech is synthesized by HMM speech synthesis system, and the parameters of synthesized speech emotion are modified by PAD model. Therefore, the quality of emotional speech synthesis is improved. The experimental results show that the proposed method improves the naturalness of synthesized speech and the clarity of emotion and also achieves good performance among different male speakers.
