java的TTS（Text to Speech）的实现

TTS即文本变成声音即语音合成它是一个现代人工智能的基础模块（你个人工智能不能说人话还有人工智能！！！ ）

当然在现在其被广泛的商业使用就是各类阅读器和人工智能无关（但他是人工智能的人机交互的基础）

简单的TTS的实现其实不难（只需要将每个文字与其对应的声波文件对应并播放出对应的输入的文字的声波文件就行），但它难就难在文字太多发声太多，最完美的就是将所有的声音全部全部记录（不好搞啊）

微软用vs写的有比较的TTS例子，但java能找到的比较少

这儿提供我的TTS的wav文件下载入口：http://download.csdn.net/detail/gudujohn/9387988

TTS简单实例（此处使用JMF播放的声音文件）：

1、找到输入文字对应的声音文件

	}

}

2、播放相应的声音文件

package ss_engine.Impl;

import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;

import ss_engine.ICharactorTool;
import ss_engine.ISpeakSound;

//播放声音的类
public class SpeakSoundImpl implements ISpeakSound {
	// 播放对象
	private Player player;
	//播放一段声音
	private List files;
	//播放一个音频
	private String file;
	//是否是一个音频
	private boolean single = true;
	private SpeakSoundImpl speakSoundImpl = null;
	public static boolean run = false;
	private int speed = 400;
	
	public void setSpeed(int speed) {
		this.speed = speed;
	}

	public SpeakSoundImpl(String needSpeak, boolean url) {
		if (url) {
			this.file = needSpeak;
			this.single = url;
		} else {
			ICharactorTool myPinYin = new MyGetPinYin();
			try {
				this.files = myPinYin.getNcnFullSpell(needSpeak);
				for(String s:files)
					System.out.println(s);
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			this.single = url;
		}
		this.speakSoundImpl = this;
	}

	/**
	 * 获取声音文件路径
	 */
	public List getSoundSource() {
		List mediaLocators = new ArrayList();
		try {
			if (single)
				mediaLocators.add(new File(file).toURI().toURL());
			else {
				for (String s : files)
					mediaLocators.add(new File(s).toURI().toURL());
			}
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return mediaLocators;
	}

	/**
	 * 播放声音文件
	 */
	public void playSound() {

		try {
			for (URL mediaLocator : speakSoundImpl.getSoundSource()) {

				player = Manager.createPlayer(mediaLocator);
				
				player.start();
				try {
					Thread.currentThread().sleep(speed);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
		} catch (NoPlayerException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

	@Override
	public void run() {
		playSound();
		run = false;
	}

}

3、调用

	@Test
	public void fun4() {
		MyGetPinYin.setPath("D:\\pinyin\\");
		String test2 = "大家好";
		ISpeakSound play = new SpeakSoundImpl(test2, false);
		Thread thread = new Thread(play);
		SpeakSoundImpl.run = true;
		thread.start();
		while(SpeakSoundImpl.run){}
	}

这儿使用的声音类库比较少只有中文对英文和特殊符号（包括空格没有处理）所以声音比较机械

我第一次完成时惊呆了 这不就是过去过去电音中的机器人发声吗 原来TTS在很早就被实现了 可以推测人工智能也在很早就被人们探索和开发了（感叹人类智慧的伟大）
