音节是维吾尔语的最小发音单元,所以大部分维吾尔语语音合成系统以音节作为基本的合成单元,但维吾尔语中音节数量很大,语料库很难保证覆盖所有的音节样本,这会导致合成语音不稳定和不连续。为解决合成语音不稳定的情况,提出了结合单音素和三音素两个不同基元的单元挑选算法。通过在单元挑选模块中加入韵律参数相匹配的方法选出最佳韵律匹配的单元并解决了合成语音不连续的情况。实验结果表明,提出的方法有效地解决了合成语音不稳定和不连续的现象,从而提高了合成语音的自然度。 Syllables are the smallest unit of pronunciation in Uyghur. Therefore, most Uyghur speech synthesis systems use syllables as the basic unit of synthesis. However, the number of syllables in Uyghur language is large. It is difficult for the corpus to guarantee coverage of all syllable samples, Stable and discontinuous. In order to solve the unstable situation of synthesized speech, a cell selection algorithm combining two different primitives of mono phoneme and triphone is proposed. The optimal prosody matching unit is selected by adding the prosodic parameters in the unit selection module and the situation of the synthesized speech discontinuity is solved. Experimental results show that the proposed method can effectively solve the problem of instability and discontinuity of synthesized speech, thus improving the naturalness of synthesized speech.
