| 摘 要： | 通过对线谱对(LSP)在语音分析和合成中的计算机模拟实验,证明了LSP参数是频域内的参数,可以直接跟踪共振峰,进行基音提取和清/浊音判断;具有较好的平稳性、内插特性和量化特性.利用频谱性质,提出了用双向比较求取LSP参数的方法,能有效地简化求解运算。与PARCOR参数相比,要得到同等音质的语音,用LSP参数可减少25％左右的数码率。

| Abstract: | A new group of LPC parameters, LSP, is studied for use in speech analysis and synthesis. Experiments proved that LSP are frequency - domain parameters which can track formants directly and can detect pitch and differentiate voiceless / voiced sounds easily, and at the same time have good stability and distinguished characteristics in interpolation and quantization. A method is given for LSP parameters computation using two - side comparison by spectrum property. It can simplify computation in analysis. It has been reported that LSP coding can maintain the same speech quality as the lattice filter synthesizer, with a 25% bit rate reduction. |
