QtSpeech会让Qt说话

2024-07-20 02:41:03   219人阅读

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.

QtSpeech的官方项目主页在: http://lynxline.com/projects/qtspeech

源码git仓库地址则在: http://gitorious.org/qt-speech

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

  1. <blockquote>#include <QtSpeech> 
  2. …  
  3. QtSpeech voice;  
  4. voice.say(“Hello World!”); 

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

  1. <blockquote>#include <QtSpeech> 
  2. …  
  3. QtSpeech * voice = new QtSpeech(this);  
  4. voice->tell(“Hello asynchronous world!”);  

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

  1. voice->tell(“Hello!”, this, SLOT(onSpeechFinished()));  

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

  1. QtSpeech::VoiceNames vs = QtSpeech::voices(); 

//不过，目前从源代码来看只支持英语

在ubuntu下编译

  1. $ #qtspeech 依赖的tts是festival，所以需要先安装  
  2. $ sudo apt-get install festival festival-dev  
  3. $ sudo apt-get install libasound2-dev  
  4. $ git clone git://gitorious.org/qt-speech/qt-speech.git  
  5. $ cd qt-speech/  
  6. $ qmake QtSpeech.pro  
  7. $ make  
  8. $ #test 

目录下有可以测试的例子，记得把音箱打开

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!”

By admin | Published: February 10, 2011

 

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 
3QtSpeech voice;
4voice.say("Hello World!");

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

 
1QtSpeech * voice = new QtSpeech(this);
2voice->tell("Hello asynchronous world!");

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

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

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

 
1QtSpeech::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.
