android 中文语音

Android 系统自带的TTS (Text To Speak)语音库目前只有English ,German , Italian ,French ,Spanish(英文,德语,意大利语,法语,西班牙语)五个音库.所以中文发音必须要借助其他的软件,或者引擎.近些天研究目前有三个方法可以实现:

1,一种是借助shoushuotts音库引擎和jar文件在自己的项目中调用.具体方法可查看网址:http://dev.10086.cn/cmdn/bbs/thread-58426-1-1.html

(经过测试,中文发音很慢,用些多音字和特殊符号无法识别)

2.是用addr软件,方法同上,要添加两个jar文件.有源代码实例:

(测试发现,其中文发音是老外的调调,并且严重怀疑他的中文也是老外教的)

3 安装讯飞语音插件.需要安装两个文件,讯飞语音TTS.apk 和讯飞语音包.apk,不需要jar文件,直接到系统配置 -> 语音输入与输出 --> 文字转语音设置 -->讯飞语音后边打钩(选择后才能设置其他项) -- > 默认引擎(讯飞语音) -->语言(中文) (用必要是还可以在讯飞语音合成里选择男声和女声)

配置完成后,可直接用系统提供的TextToSpeak的方法直接调用即可.

(测试发现,改发音是中标准的中文发音,据了解,国内语音识别系统做的最好的一家,发音连贯,并且可辨认符号如℃等)

示例代码如下:
