本文档介绍Sphinx4在Windows下的中文训练过程及注意事项,与本文档配套的是我自己的训练实例bergtrain和用到的软件。
本文档编写日期2013-04-231、为什么要训练?sphinx4目前的版本中仅提供了英文等语音识别库。
中文的库是PTM或semi类型的,在java版sphinx中无法使用。
2、Sphinx的训练指哪些内容?在Sphinx中有语言模型、声学模型等概念,如果你不想了解这些,请参考以下内容:a1、中文每个字的标准发音已经有一个较为全面的文件进行了标注这个文件就是zh_broadcastnews_utf8.dic(下称这类文件为发音字典),在sphinx网站上可以下载,我们也包含了它。
下面是该文件的片断,它用类似拼音的方式标注了每个字或词的发音。
昌chang昌北changbei昌必changbi昌都changdu昌赫changhea2、需要告诉sphinx我们经常使用的字、词是哪些,它们出现的频率如何由于开放式语音识别尚难实现,所以sphinx实际上只能较好的处理相对小的语言集合。
因此,针对特定的领域,告诉sphinx该领域的词汇和各词出现的频率将极大提高识别率。
a3、需要告诉sphinx每个字、词的真正读音发音字典告诉sphinx每个字的标准读音,但面对的说话人往往不会以标准读音来朗读。
因此sphinx需要学习说话人的“口音”。
如果训练时的读者发音比较标准,则sphinx能“举一反三”,识别其他不那么标准的读者的语音。
推荐的做法是训练一些典型的口音:标准男、女声,童音,最后再考虑特定用户的口音。
3、如何准备训练内容所需的原料?需要准备两大内容:1)文本语料文件,2)语料录音文件。
文本语料文件给出2.a2中需要的内容,在bergtrain的etc文件下的berginput.txt文件就是一个预料文件。
它以行为单位,给出了150个中文句子。
语料录音文件是根据文本语料文件,朗读它的每行/句话,保存到每一个语音文件即可。
语料文件中的语句应该尽量选择领域相关的,在覆盖领域内名词的前提下,覆盖尽可能多的通用词汇。
4、训练环境及注意事项本文的训练软硬件如下:硬件:T60P笔记本,机器自带录音设备;
操作系统为Win732位。
软件:Sphinx cmuclmtk-0.7-win32.zip pocketsphinx-0.8-win32.zip sphinxbase-0.8-win32.zip sphinxtrain-1.0.8-win32.zip sphinx4-1.0beta6-bin.zip,用于编写java版的识别软件所需的库 脚本执行软件 ActivePerl-5.16.3.1603-MSWin32-x86-296746.msi ActivePython-2.7.2.5-win32-x86.msi 录音和处理软件 audacity-win-2.0.3rc1.zip,可进行录音和声音文件处理(如降噪),免费软件 FairStars.zip,可进行批量录音(V3.5绿色版) 文本编辑软件UltraEdit,UltraEdit-32.rar绿色版注意: 文件格式 语料文件必须使用UltraEdit进行编辑, 在编辑后,使用文件-转换-ASCII转UTF-8(UNICODE编辑),指定文件中的中文使用utf8编码。
在保存前,设置格式如下: 换行符:UNIX终束符-LF 指定文件中的回车/换行符为编码0A的换行符 格式:UTF-8-无BOM 每个文件的末尾必须有一个回车! 这个回车将在保存时被替换为编码0A的换行符,训练脚本需要这个符号来确认文件的结束。
录音文件 如果你不希望去编辑训练中的配置文件,则在使用FairStars录音时作如下设定: 进入菜单和对话框选项-显示录音选项-编码-WMA, 设定:采样率(16000Hz)、通道(单声道)、比特率(16Kbps)5、训练步骤下面逐步从零开始进行训练5.1软件环境的安装将本文档所在的文件夹解压或拷贝到d:\,即本文档路径是d:\sphinxtrain\Sphinx中文训练教程.txt1)点击安装ActivePerl-5.16.3.1603-MSWin32-x86-296746.msi和ActivePython-2.7.2.5-win32-x86.msi;
2)解压Sphinx中除sphinx4-1.0beta6-bin.zip外的压缩文件到d:\sphinxtrain下

本文件功能:用BP神经网络预测温湿度。
本次仿真,预测模型为8*8*8*1,输入数据为359天数据(一个小时测一个数据,一天数据为24)。
其中350天数据做训练样本,用来训练BP网络模型的权值和阈值,4天用来做测试样本,用来测试3天左右的温湿度预测值。
本次训练效果比较上次仿真较为准确,判定系数可以达到0.8左右(越靠近1表明仿真效果越好),预测值与实际值点状图基本围绕在主对角线左右,MSE平方误差可以达到0.01,BP网络预测输出图也可以看出预测值的变化趋势基本与期望值一致。
本次仿真存在不足:1.未修改学习率、附加动量等参量没有解决BP网络收敛慢的问题。
2.没有使用全局优化的算法,没有解决BP容易陷入极值点的问题。
这种用BP网络来进行预测的模型网上有很多,但是大多数都是预测风力发电等,可能也是因为该BP模型是40年代所提出,我是没有找到有温湿度的预测,该代码纯属自己改写的,并且运行无误,现在分享出来,让大家节省一些时间去研究更有深度的算法。

中文名:CiscoIPv6网络实现技术原名:CiscoSelf-Study:ImplementingCiscoIPv6Networks作者:RegisDesmeules译者:王玲芳张宇李颖华孙向辉资源格式:PDF版本:扫描版出版社:人民邮电出版社书号:7115118108发行时间:2004年地区:大陆语言:简体中文,英文简介:前言IPv6在1992年由IETF推出。
与IPv4地址空间匮乏相比,IPv6在今天看来将成为基本的、容易安装的解决方案。
由于其设计基于IPv4协议过去20年的经验,IPv6的效率较IPv4有显著的提高。
对于IPv6,我们不得不改变思维方式,因为IPv6协议不仅仅是为网络(如当前的IPv4因特网)上的计算机而设计的。
IPv6应用于所有的通信设备,如蜂窝设备、无线设备、电话、个人数字助理、电视、广播设备等,而不只限于计算机。
IPv6的一个主要目标是通过简化任何基于IP网络的实施、运营和管理,使路由器成为网络的关键组件。
而且,对于将有数十亿个节点设备的全球网络,如3G基础设施,IPv6比IPv4更先进,更具规模扩展性。
IPv6的一些优势包括:巨大的地址空间、简单的数据包头、自动配置、网络重编号、网络聚合、多穴、过渡以及与现有的IPv4基础设施并存。
从长远角度来看,因特网专家和高层分析人员一致认为因特网必须升级到IPv6。
事实上,IPv6的最终目标是完全替代IPv4。
因此,IPv6的长远市场是巨大的,意味着世界各地的数十亿台节点设备和网络。
Cisco系统公司是全球领先的网络互连硬件和软件供应商。
Cisco从1995年(即IPv6的早期设计阶段)开始就参与了IETFIPv6的标准化过程。
因为Cisco技术承载着全部因特网流量的80%,显然,Cisco是IPv6在全球实施的一个关键角色。
注:因为在本书中,要列出一份最新的CiscoIOS软件技术为不同平台已经或将要支持的IPv6功能列表是困难的,建议您访问www.cisco.com获得最新的可用功能列表。
可以在“从这儿开始:CiscoIOS软件版本IPv6功能”手册中找到最新列表,也可以在CCO功能导航中找到最新列表。
本书目标全面理解IPv6技术机制、CiscoIOS软件技术的IPv6新功能、Cisco路由器与IPv6实现的互操作性对实施可扩展的、可靠的IPv6网络是最基本的。
因此,本书重点介绍CiscoIPv6的实现,以及在Cisco路由器上设计、配置、部署和调试IPv6的深入的技术参考。
通过书中所有的IPv6功能操作实例,您将获得Cisco技术IPv6的专门知识。
本书读者本书面向企业和提供商市场的专业人员,如规划人员、网络设计者、系统工程师、网络经理、管理员以及任何技术人员。
那些计划使用Cisco技术实施IPv6网络、提供IPv6连接并在网络骨干中应用IPv6的专业人员有必要阅读本书。
因为本书提供了许多应用IPv6和CiscoIOS软件技术的例子、图解、IOS命令和建议,您将发现本书是值得一读的。
本书包含描述、设计、配置、维护和运营基于Cisco路由器的IPv6网络骨干的所有知识。
为了全面理解本书的知识,您需要有一点儿IPv4的背景并能够操作Cisco路由器。
本书结构虽然您可以逐页地通读全书,但本书的设计灵活,您可以随意地跳读任何章节,方便地查找到您所需要的内容。
本书分为五部分。
第一部分介绍了IPv6的发展过程、理论基础和优势。
第二部分详细说明IPv6的基本特征和高级特征,然后解释使用CiscoIOS软件技术进行设计、应用、配置和路由IPv6网络。
第三部分讲述主要的整合和共存机制,并描述使用不同的策略、在当前的IPv4基础设施上整合IPv6。
这部分还包括了使用CiscoIOS软件技术与不同的支持IPv6主机实现进行网络互联的例子。
第四部分叙述6bone的设计,以及这个全球范围的IPv6骨干的运作机制。
这部分还提供了一些信息,帮助ISP了解在IPv6因特网上成为IPv6提供商的步骤和规则。
第五部分包括附录和术语表。
下面重点说明了涉及的主题和本书的组织结构:第一部分:IPv6综述和缘由第1章IPv6介绍本章概述了新的IPv6协议。
通过指出IPv4的问题,如IPv4地址空间枯竭、快速增长的全球因特网路由选择表以及应用网络地址转换(NAT)机制的许多隐含条件,从而更具体地探讨了IPv6的理论依据。
本章还介绍了IPv6的发展过程,并综述了IPv6的各种特征,如巨大的地址空间、地址层次结构、网络聚合、自动配置、网络重编号、有效的包头、移动性、安全性以及从IPv4到IPv6的过渡。
第二部分:IPv6设计.第2章I

分布式温控系统基本要求假定,某快捷廉价酒店响应节能绿色环保理念,推行自助式房间温度调节的空调系统,经过初步分析该系统的基本需求如下:1. 空调系统由中央空调和房间空调两部分构成;
2. 中央空调是冷暖两用,根据季节进行模式调整。
a) 当设置为供暖时,供暖温度控制在25°C~30°C之间;
b) 当设置为制冷时,制冷温度控制在18°C~25°C之间。
3. 中央空调具备开关按钮,只可人工开启和关闭,中央空调正常开启后处于待机状态。
a) 中央空调开机后,无论哪一种工作模式,缺省工作温度为25°C;
b) 当关闭后,不响应来自房间的任何温控请求;
c) 当有来自从控机的温控要求时,中央空调开始工作;
d) 当所有房间都没有温控要求时,中央空调的状态回到待机状态。
4. 房间内有独立的从控空调机,但没有冷暖控制设备。
a) 从控机具有一个温度传感器,实时监测房间的温度,并与从控机的目标设置温度进行对比,并向中央空调机发出温度调节请求。
b) 如果从控机发出的请求和中央空调设置的冷暖控制状态发生矛盾时,以中央空调机的状态优先,否则中央空调机不予响应。
5. 从控机只能人工方式开闭,并通过控制面板设置目标温度,目标温度有上下限制。
a) 从控机开机后动态获取房间温度,并将温度显示在控制面板上;
b) 从控机开机后与中央空调连接获取工作模式,并将工作模式显示在控制面板上;
6. 控制面板的温度调节可以连续变化也可以断续变化:a) 温度调节按钮连续两次或多次指令的时间间隔小于1s时,从控机只发送最后一次的指令参数;
b) 如果温度调节按钮连续两次的时间间隔大于1s时,从控机将发送两次指令参数;
7. 房间目标温度达到后,从控机自动停止工作。
a) 房间温度随着环境温度开始变化,当房间温度超过目标温度1°C时,重新启动;
b) 房间不考虑大小和管道的分布及大小问题,在达到目标温度后,房间温度每分钟上下变化X°C(各小组自行定义环境温度的变化曲线)。
8. 中央空调能够实时监测各房间的温度和状态,并要求实时刷新的频率能够进行配置;
9. 要求分控机的控制面板能够发送高、中、低风速的请求,要求各小组自定义高、中、低风情况下的温度变化值;
比如以中风为基准,高速风的温度变化曲线可以提高25%,低速风的温度变化曲线可以降低25%。
10. 系统中央空调部分具备计费功能:可根据中央空调对分控机的请求时长及高中低风速的供风量进行费用计算;
a) 每分钟中速风的能量消耗为一个标准功率消耗单位;
b) 低速风的每分钟功率消耗为0.8标准功率;
c) 高速风的每分钟功率消耗为1.3标准功率;
d) 并假设,每一个标准功率消耗的计费标准是5元。
11. 中央空调监控具备统计功能,可以根据需要给出日报表、周报表和月报表;
报表内容如下:房间号、开关机的次数、温控请求起止时间、温控请求的起止温度及风量大小12. 中央空调同时只能处理三台分控机的请求,为此主机要有负载均衡的能力,能够保证所有房间的请求都能进行温度调整。

为了抑制现有平行分束偏光镜剪切差较小且不可调谐的缺陷,拓宽平行分束偏光镜的使用规模,付与冰洲石晶体以及两块间距可调的三角形玻璃棱镜,制作出造价相对于低廉、剪切差大规模内可调谐、且具备良好的分束比以及透射比的复合式剪切差可调谐平行分束偏光镜。
从实际上阐发了该复合式棱镜的剪切差可调谐规模、e光以及o光的分束等到未镀增透膜的情景下总的透射比随复合式棱镜中玻璃棱镜的结构角及两块玻璃棱镜的间距等结构参数的变更,并给出了仿真盘算下场。
依据该下场方案了试验样品,剪切差在1.4~50.2妹妹规模内可调谐,e光以及o光的光强分束比优于1.1,且在未镀增透膜的情景下总的透射比大于80%。

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
