语音语音合成科大讯飞和Tizen-TTS语音合成引擎

废话就不多说了，开始。。。

最近在做一个文本转语音TTS(Text to Speech)的第三方软件封装，应用的是海内语音技术龙头安徽科大讯飞公司提供的离线引擎AiSound5.0，重要用于汽车导航用途。科大讯飞还提供了AiTalk用于语音识别，AiWrite用于手写识别服务等。另外还有针对6种平台的SDK和开辟示例。

一、科大讯飞语音平台

科大讯飞目前有不少产品应用在移动终端上了，比如说用在手机上的讯飞语点，可方便语音拨打电话和发送短信，查气候、股票等信息。

在上面讯飞语音云这个网站可以找到科大讯飞针对6种平台的SDK，http://open.voicecloud.cn/download.php，包含Android、Iphone、Windows、Linux、Java、Flash这些平台的语音合成、语音识别和语音听写的开辟文档和SDK下载，不过应用之前须要请求AppID(每一个语音应用程序须要一个Appid来独一标识，您须要通过注册帐号来获得自己应用的Appid，未注册的语音应用将无法正常获取语音服务。)，通过考核后就可以下载响应的开辟文档和SDK并用于自己的软件系统中了。

二、科大讯飞语音合成、识别-在线文档和应用程序示例网址

文章结束给大家分享下程序员的一些笑话语录：问路
有一个驾驶热气球的人发现他迷路了。他降低了飞行的高度，并认出了地面上的一个人。他继续下降高度并对着那个人大叫，“打扰一下，你能告诉我我在哪吗？”
下面那个人说：“是的。你在热气球里啊，盘旋在 30 英尺的空中”。
热气球上的人说：“你一定是在 IT 部门做技术工作”。
“没错”，地面上的人说到，“你是怎么知道的？”
“呵呵”，热气球上的人说，“你告诉我的每件事在技术上都是对的，但对都没有用”。
地面上的人说，“你一定是管理层的人”。
“没错”，热气球上的人说，“可是你是怎么知道的？”
“呵呵”，地面上的那人说到，“你不知道你在哪里，你也不知道你要去哪，你总希望我能帮你。你现在和我们刚见面时还在原来那个地方，但现在却是我错了”。
