想要多瞭解QtSpeech，那麼隨著本文的文字往下走吧！QtSpeech是一個Qt封裝的跨平台TTS(文本變成語音輸出)API，在不同平台下利用系統內建的TTS引擎。在Windows下使用SAPI, 在Mac下使用SpeechSynthesis，而在Linux下使用 Festival.

QtSpeech的官方項目首頁在: http://lynxline.com/projects/qtspeech

源碼git倉庫地址則在: http://gitorious.org/qt-speech

API的使用非常簡單，如果你是同步調用，發音結束後返回，可以使用QtSpeech::say

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

如果是非同步呼叫(發音不會阻塞程式運行)，則可以使用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，還可以加入slot函數，在發音結束時回調該slot

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

VoiceName可以用於設定發音類型的，比如英語或者法語，意大利語等

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

//不過，目前從原始碼來看只支援英語

在ubuntu下編譯

1. $ #qtspeech 依賴的tts是festival，所以需要先安裝  
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 

目錄下有可以測試的例子，記得把音箱開啟

小結：QtSpeech就介紹到這裡吧，注意了，標頭檔得自己手動添加，如果還出錯的話，那就是你沒裝Qt開發包！！！不要飯低級錯誤哦。

 

 

 

 

 

 

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

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.
