查询词典 signal

In accordance with the actual project, this paper fully considers the comprehensive factors of speaker recognition system on the basis of explaining speaker recognition's principle, such as recognition rate, recognition speed, system stability etc. LPCC is used as the feature parameter. LPCC can reflect the esthesia feature of human in pronunciation and has offered a group of succinct speech signal model parameters which signify the range of frequency spectrum of the speech signal more accurately and the operation amount is not comparatively big. Combined vector quantization technology, the speech searched system has been developed.

本文依拖实际项目，在阐述说话人识别原理的基础上，充分考虑说话人识别系统的识别率、识别速度、稳定性等综合因素，采用能够反映人对语音的感知特性的线性预测倒谱系数LPCC 作为特征参数，LPCC 的重要性还在于，它提供了一组简洁的语音信号模型参数，这一组参数较精确地表征了语音信号的频谱幅度，而分析它们所需的运算量相对来讲却不大；同时结合矢量量化技术，成功开发出语音检索系统。
