| 摘 要： | 为实现可视语音合成，建立符合条件的双模态语料库，提出双模态语料自动选取算法。根据视频中唇部发音特征，对已有的三音子模型归类，形成视频三音子，在其基础上从原始语料中自动选取语料，利用评估函数对原始语料中的句子打分。与其他双模态语料库相比，该语料库在覆盖率等指标上有较大改进，为实现具有真实感的可视语音合成奠定基础。

| Abstract: | In order to realize visual speech synthesis,a satisfied bimodal database needs to be built up. This paper proposes an automatic corpus selection algorithm,according to features of lip pronunciation in video,visual triphone modal is established. Proposed algorithm automatically selects corpus from original corpus. Evaluation function is utilized to score sentences from original corpus. Compared to other bimodal databases,coverage rate,coverage efficiency and high-frequency words distribution are greatly impr... |
