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。

Vectorgraph can be converted to a bitmap, but in turn bitmap converted to vectorgraph technical comparison difficult to achieve, a lot of graphic design software that support the use of pixel figure converted to vectorgraph, a general description of the software for free vector function realization, so that we can on the basis of vectorgraph to do the editing, but this kind of conversion sometimes is time-consuming, and sometimes does not achieve the expected results, it is generally used for relatively simple bitmap, or you would like some special effects.

矢量图可以转换成位图，不过反过来把位图转换为矢量图技术上比较难实现，很多图形设计软件都支持将像素图转换成矢量图性，一般可用矢量软件的描摹功能实现，这样我们就可以在矢量图形的基础上再做编辑，但这样的转换有时候会很耗时，有时候并不能达到预想的效果，一般用于比较简单的位图，或者想要表现一些特殊的效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
