利用百度语音接口我为女儿写个英语阅读器原来这么简单

今日本来想接昨天的话题，继续说黑客控制手机的事，听到女儿说，英语听力变差了，好吧，今天写个英语朗读器。英语只是出师有名，其实汉语也行，我估计其它语言也行，只不过我不会，没有测试。

以上是效果图。

说说原理吧。要播放mp3要有什么？第一，要有播放器吧，第二，要有mp3文件吧。

播放器可以调用媒体播放器。

mp3文件恰好百度有个接口：http://tts.baidu.com/text2audio?lan=zh&ie=UTF-8&spd=4&per=5&pit=5&text=" + t3

其中t3就是我们要朗读的字符串。

好吧，开始。
