1.概述 Lemon是一个LALR(1)文法分析器生成工具,与bison和yacc类似,是一个可以独立于SQLite使用的开源的分析器生成工具.而且它使用与yacc(bison)不同的语法规则,可以减少编程时出现错误的机会.Lemon比yacc和bison更精致.更快,而且是可重入的,也是线程安全的——这对于支持多线程的程序是非常重要的. Lemon的主要功能就是根据上下文无关文法(CFG),生成支持该文法的分析器.程序的输入文件有两个: (1) 语法规则文件: (2) 分析器模板文件. 一般来…

FLEX 什么是FLEX?它是一个自动化工具,可以按照定义好的规则自动生成一个C函数yylex(),也成为扫描器(Scanner).这个C函数把文本串作为输入,按照定义好的规则分析文本串中的字符,找到符合规则的一些字符序列后,就执行在规则中定义好的动作(Action).例如在规则中可以这样定义:如果遇到一个换行字符\n,那么就把行计数器的值加一. Flex文件就是一个文本文件,内容包括定义好的一系列词法规则.文件的命名习惯上以小写字母l(L)来作为文件后缀.如果为了清晰,也可以用.flx或者.f…

利用微软Speech SDK 5.1开发语音识别系统主要步骤 2009-09-17 10:21:09|  分类: 知识点滴|字号 订阅 微软语音识别分两种模式:文本识别模式和命令识别模式.此两种模式的主要区别,主要在于识别过程中使用的匹配字典不同.前者使用的是通用字典,特点是内容多,覆盖的词汇量大,字典由sdk提供.适用于没有预定目标的随机听写之类的应用.同时因为词汇量大直接导致识别的精度降低,识别速度较慢.后者的字典需要 开发者自己编写,就是你们所说的xml文件.xml文件作为一种数据存储的方…

摘要:解析器就是编译原理中的语言的词法分析器,可以按照文法规则提取字符或者单词.功能:接受扫描器的输入,并根据语法规则对输入流进行匹配,匹配成功后执行语义动作,进行输入数据的处理. C++ 程序员需要面对的最复杂的任务之一就是在一段合理的时间期限内编写一个解析器.在为 SQL 或 C++ 这类成熟的语言开发编译器时,使用 GNU Flex/Bison 或 ANTLR 解析器生成程序通常是不错的选择:但是对于使用更简单的 Backus Naur Form(BNF)的语法,这些工具陡峭的学习曲线并不…

第二章:字符串和文本 几乎所有有用的程序都会涉及到某些文本处理,不管是解析数据还是产生输出. 这一章将重点关注文本的操作处理,比如提取字符串,搜索,替换以及解析等. 大部分的问题都能简单的调用字符串的内建方法完成. 但是,一些更为复杂的操作可能需要正则表达式或者强大的解析器,所有这些主题我们都会详细讲解. 并且在操作Unicode时候碰到的一些棘手的问题在这里也会被提及到. 2.1 使用多个界定符分割字符串关键:str.split(str="", num=string.count(st…

1.原理 语音操控分为 语音识别和语音朗读两部分. 这两部分本来是需要自然语言处理技能相关知识以及一系列极其复杂的算法才能搞定,可是这篇文章将会跳过此处,如果你只是对算法和自然语言学感兴趣的话,就只有请您移步了,下面没有一个字会讲述到这些内容. 早在上世纪90年代的时候,IBM就推出了一款极为强大的语音识别系统-vio voice , 而其后相关产品层出不穷,不断的进化和演变着. 我们这里将会使用SAPI实现语音模块. 2. 什么是SAPI? SAPI是微软Speech API , 是微软公司推…

Python 语音 实现语音操控的原理 语音操控分为语音识别和语音朗读两部分 我们使用speech模块实现语音模块(python 2.7) SAPI是微软Speech API , 是微软公司推出的语音接口,而细心的人会发现从WINXP开始,系统上就已经有语音识别的功能了,可是用武之地相当之少,他并没有给出一些人性化的自定义方案,仅有的语音操控命令显得相当鸡胁. Python pywin32,可以使Python调用WIN32COM接口,选择对应版本下载(区分32位/64位),直接双击运行即可 安装…
