摘要 语音谱包络提取是语音分析中的重要内容。提出了分段线性预测技术用于提取语音谱包络参数。结合滤波器组理论和线性预测模型,首先对语音频段进行划分,然后在不同的频带进行线性预测。实验证明,合成的语音频谱分辨率有了很好的改善。 In speech analysis, it's very important for the extraction of speech spectral envelope, An algorithm is presented using piecewise LPC(Linear Predictive Coding). The theory of filter banks is used as well as LPC. The spectral coverage of speech is divided, and then LPC is applied to different spectral bands. Experiments suggest that the resolving capability of synthetic spectra is improved.
