BlackBerry 10 uses Google TTS to read Chinese text, developing language C + + Qt Cascade

First, let's test Google tts English text aloud

Command-line testing:
Wget-q-u mozilla-o "Helloworld.mp3" "http://translate.google.com/translate_tts?ie=UTF-8&tl=en&q=hello+ World

Then we write a section of QT Code, test Chinese speech aloud, download the file name Translate_tts, the mobile phone in the application of the data directory, such as

/accounts/1000/appdata/com.example.hello1standard.testdev_lo1standard73e1edad/data

We can copy this mp3 file to the BlackBerry 10 Windows network disk, and then connect the handset USB to the PC and play on the PC computer. It can also be played directly on the phone using the "Music" program.

CP Translate_tts.mp3/accounts/1000/shared/music/helloworld.mp3

The QT code is as follows:

	/** set encoding begin  **/
	qtextcodec *codec = Qtextcodec::codecforname ("UTF-8");
	Qtextcodec::setcodecforlocale (codec);
	Qtextcodec::setcodecforcstrings (codec);
	QTEXTCODEC::SETCODECFORTR (codec);
	/** sets the encoding end  **/

    downloadmanager* downloader = new Downloadmanager (&app);
    QString url = "http://translate.google.com/translate_tts?&tl=zh-CN&q= Beijing welcomes You";
    Qurl Qurl = qurl::fromencoded (Url.tolocal8bit ());
    Downloader->singledownload (Qurl);

Downloadmanager should be Nokia's official example code, you can google the QT downloadmanager.h
