JAVA教程之java语音完成手艺TTS材料
恰恰证明了java的简单，要不怎么没有通过c/c++来搞个这种框架？要做语音，查了一些材料。JavaSpeechAPI：http://java.sun.com/products/java-media/speech/
JavaSpeechAPI同意开辟职员将语音手艺整合到Javaapplet和使用程序的用户界面中。这类API划定一个跨平台的接口来撑持命令―把持辨认器、听写体系和语音分解器。
这个综合API被分红几个标准：
JavaSpeechAPI标准（JavaSpeechAPISpecification，JSAPI）
JavaSpeechAPI程序员指南
JavaSpeechAPI语法格局标准（JavaSpeechAPIGrammarFormatSpecification，JSGF）
JavaSpeechAPI标志言语标准（JavaSpeechAPIMarkupLanguageSpecification，JSML）
这个API没有Sun公司的参考完成，可是有很多第三方完成，包含SpeechforJava（能够从IBMalphaWorks取得），它利用ViaVoice来撑持语音命令辨认、听写和文本到语音的分解。

试用了一些产物，发明关于中文不可呀，那位先容一下呀？
而学习JAVA我觉得最应该避免的就是：只学习，不思考，只记忆，不实践！ 在全球云计算和移动互联网的产业环境下，Java更具备了显著优势和广阔前景。 你现在最缺的是实际的工作经验，而不是书本上那些凭空想出来的程序。 自从Sun推出Java以来，就力图使之无所不包，所以Java发展到现在，按应用来分主要分为三大块：J2SE,J2ME和J2EE,这也就是Sun ONE(Open Net Environment)体系。J2SE就是Java2的标准版，主要用于桌面应用软件的编程；J2ME主要应用于嵌入是系统开发，如手机和PDA的编程；J2EE是Java2的企业版，主要用于分布式的网络程序的开发，如电子商务网站和ERP系统。 是一种使网页(Web Page)由静态(Static)转变为动态(Dynamic)的语言 Java 不同于一般的编译执行计算机语言和解释执行计算机语言。它首先将源代码编译成二进制字节码（bytecode），然后依赖各种不同平台上的虚拟机来解释执行字节码。从而实现了“一次编译、到处执行”的跨平台特性。 是一种突破用户端机器环境和CPU Java是一种计算机编程语言，拥有跨平台、面向对java 所以现在应用最广泛又最好学的就是J2EE了。 J2EE又包括许多组件，如Jsp,Servlet,JavaBean,EJB,JDBC,JavaMail等。要学习起来可不是一两天的事。那么又该如何学习J2EE呢？当然Java语法得先看一看的，I/O包，Util包，Lang包你都熟悉了吗？然后再从JSP学起。 在全球云计算和移动互联网的产业环境下，Java更具备了显著优势和广阔前景。 我大二，Java也只学了一年，觉得还是看thinking in java好，有能力的话看英文原版(中文版翻的不怎么好)，还能提高英文文档阅读能力。 Pet Store.（宠物店）是SUN公司为了演示其J2EE编程规范而推出的开放源码的程序，应该很具有权威性，想学J2EE和EJB的朋友不要 错过了。 Java是一个纯的面向对象的程序设计语言，它继承了 C++语言面向对象技术的核心。Java舍弃了C ++语言中容易引起错误的指针（以引用取代）、运算符重载（operator overloading） Pet Store.（宠物店）是SUN公司为了演示其J2EE编程规范而推出的开放源码的程序，应该很具有权威性，想学J2EE和EJB的朋友不要 错过了。 当然你也可以参加一些开源项目，一方面可以提高自己，另一方面也是为中国软件事业做贡献嘛！开发者在互联网上用CVS合作开发，用QQ,MSN,E-mail讨论联系，天南海北的程序员分散在各地却同时开发同一个软件，是不是很有意思呢？ 当然你也可以参加一些开源项目，一方面可以提高自己，另一方面也是为中国软件事业做贡献嘛！开发者在互联网上用CVS合作开发，用QQ,MSN,E-mail讨论联系，天南海北的程序员分散在各地却同时开发同一个软件，是不是很有意思呢？ 你可以去承接一些项目做了，一开始可能有些困难，可是你有技术积累，又考虑周全，接下项目来可以迅速作完，相信大家以后都会来找你的，所以Money就哗啦啦的。。。。。。 你快去找一份Java的编程工作来做吧（如果是在校学生可以去做兼职啊），在实践中提高自己，那才是最快的。不过你得祈祷在公司里碰到一个高手，而且他 还愿意不厌其烦地教你，这样好象有点难哦！还有一个办法就是读开放源码的程序了。我们知道开放源码大都出自高手，他们设计合理，考虑周到，再加上有广大的程序员参与，代码的价值自然是字字珠叽，铿锵有力（对不起，偶最近《金装四大才子》看多了）。 接着就是EJB了，EJB就是Enterprise JavaBean, 看名字好象它是Javabean，可是它和Javabean还是有区别的。它是一个体系结构，你可以搭建更安全、更稳定的企业应用。它的大量代码已由中间件（也就是我们常听到的 Weblogic,Websphere这些J2EE服务器）完成了，所以我们要做的程序代码量很少，大部分工作都在设计和配置中间件上。 那么我书也看了，程序也做了，别人问我的问题我都能解决了，是不是就成为高手了呢？当然没那么简单，这只是万里长征走完了第一步。不信？那你出去接一个项目，你知道怎么下手吗，你知道怎么设计吗，你知道怎么组织人员进行开发吗？你现在脑子里除了一些散乱的代码之外，可能再没有别的东西了吧！
