| 摘 要： | 提出了一种在离散变换域中合成语音信号的方法,建立语音线性预测模型,对语音信号分帧、加窗,然后进行线性预测和基音周期的提取,进而模拟重构语音信号。实验表明,该方法易于实现,可操作性强,重建的语音信号还原的声音精度高,并能节省信号传输的带宽,相比以往的方法更能方便、准确的重构合成语音信号。

| Abstract: | A method of synthesising speech signal based on the discrete proposed. Speech linear prediction model is set up. Firstly, the speech signal and window, then linear prediction and pitch period extraction are added, in transform domain is is divided into frames order to simulate and reconstruct speech signal. Extensive experimental results show that the proposed algorithm is simple, invisible and maneuverable,with the high precision of the reconstruction speech signal. The proposed algorithm is saved transmission bandwidth by convenient and accuration compared with other algorithm. |
