QtSpeech会让Qt说话

想要多了解QtSpeech，那么随着本文的文字往下走吧！QtSpeech是一个Qt封装的跨平台TTS(文本变成语音输出)API，在不同平台下利用系统自带的TTS引擎。在Windows下使用SAPI, 在Mac下使用SpeechSynthesis，而在Linux下使用 Festival.

API的使用非常简单，如果你是同步调用，发音结束后返回，可以使用QtSpeech::say

如果是异步调用(发音不会阻塞程序运行)，则可以使用QtSpeech::tell

如果使用QtSpeech::tell，还可以加入slot函数，在发音结束时回调该slot

VoiceName可以用于设定发音类型的，比如英语或者法语，意大利语等

小结：QtSpeech就介绍到这里吧，注意了，头文件得自己手动添加，如果还出错的话，那就是你没装Qt开发包！！！不要饭低级错误哦。

QtSpeech, say “Hello World!”

I am glad to announce new small project that got first release – QtSpeech.
This is library providing Qt-like interface to system TTS (text-to-speech) engines to allow your application to say “Hello World!”.

Current API is very simple.
First you need to include <QtSpeech>. Then if your application just needed to say something synchronously (execution will wait in the point until speech is finished) you can use such code:

1
#include <QtSpeech>

2
 
3
QtSpeech voice;

4
voice.say("Hello World!");

If you would like to do this in asynchronous way (so your application is not blocked meanwhile) just use tell() call:

 
1
QtSpeech * voice = new QtSpeech(this);

2
voice->tell("Hello asynchronous world!");

If you need to invoke a slot at the end, use:

 
1
voice->tell("Hello!", this, SLOT(onSpeechFinished()));

Also you have possibility to get list of voices and choose voice from available in your system:

 
1
QtSpeech::VoiceNames vs = QtSpeech::names()

Current implementation support Windows using SAPI and Mac. I have plans to extend API to include more functionality but will try to choose what is common on all platforms.
