【中文标题】文字转语音（TTS）-Android【英文标题】：Text to speech(TTS)-Android 【发布时间】：2011-03-04 18:54:55 【问题描述】：我是安卓平台的新手。现在我正在处理TTS(Text to Speech)。如果我在 TextArea 中输入文本，并且我希望在单击发言按钮时将其转换为语音。
谁能帮帮我？
【问题讨论】：
【参考方案1】：文字转语音内置于 android 1.6+ 中。这是一个简单的例子。
TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

Here are instructions关于如何从 Android SDK 管理器下载示例代码：
启动 Android SDK 管理器。
一个。在 Windows 上，双击 Android SDK 目录根目录下的 SDK Manager.exe 文件。
b.在 Mac 或 Linux 上，打开终端到 Android SDK 中的 tools/ 目录，然后执行 android sdk。
展开最新 Android 平台的软件包列表。
选择并下载 SDK 示例。 下载完成后，您可以在此位置找到所有示例的源代码：/sdk/samples/android-version/
(i.e. \android-sdk-windows\samples\android-16\ApiDemos\src\com\example\android\apis\app\TextToSpeechActivity.java)
【讨论】：
+1 用于指出每个平台版本的最佳方法。 SDK 示例。 我得到的speak 目前已弃用
因为没有被弃用的是：speak(CharSequence text, int queueMode, Bundle params, String utteranceId)
您必须等待 TTS 初始化。
要导入的西班牙语和土耳其语以及其他语言呢？【参考方案2】：
MainActivity.class

import android.content.SharedPreferences.Editor;
import android.speech.tts.TextToSpeech;
import android.util.Log;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et=(EditText)findViewById(R.id.editText1);
tts=new TextToSpeech(MainActivity.this, new TextToSpeech.OnInitListener()

text = et.getText().toString();
if(text==null||"".equals(text))
text = "Content not available";
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
else
tts.speak(text+"is saved", TextToSpeech.QUEUE_FLUSH, null);

【讨论】：
这是一个更完整的例子。它包括接受的答案中缺少的 TextToSpeech.OnInitListener 的实现。好东西！ +1 感谢这些好东西！！ +1 .. 但是，如果我使用 1000 多个单词（听起来像 PDF），我可以用“恢复”选项实现“播放”和“暂停”吗？ tts.shutdown() 应该移到 onDestroy() 方法中。【参考方案3】：快速测试 TTS 系统的简约示例：
private TextToSpeech textToSpeechSystem;
@Override
protected void onStart()
super.onStart();
textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener()
@Override
public void onInit(int status)
if (status == TextToSpeech.SUCCESS)
String textToSay = "Hello world, this is a test message!";
textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
);
如果您不使用本地化消息，textToSpeechSystem.setLanguage(..) 也很重要，因为您的用户可能并非都将英语设置为默认语言，因此单词的发音会出错。但是对于一般的 TTS 测试来说，这个 sn-p 就足够了

【参考方案4】：试试这个，很简单： **speakout.xml：**
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:background="#3498db"
android:weightSum="1"
android:orientation="vertical" >
<TextView
android:id="@+id/txtheader"
android:layout_
android:layout_
android:layout_gravity="center"
android:layout_weight=".1"
android:gravity="center"
android:padding="3dp"
android:text="Speak Out!!!"
android:textColor="#fff"
android:textSize="25sp"
android:textStyle="bold" />
<EditText
android:id="@+id/edtTexttoSpeak"
android:layout_
android:layout_weight=".5"
android:background="#fff"
android:textColor="#2c3e50"
android:text="Hi there!!!"
android:padding="5dp"
android:gravity="top|left"
android:layout_/>
<Button
android:id="@+id/btnspeakout"
android:layout_
android:layout_
android:layout_weight=".1"
android:background="#e74c3c"
android:textColor="#fff"
android:text="SPEAK OUT"/>
</LinearLayout>
还有你的 SpeakOut.java ：
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class SpeakOut extends Activity implements OnInitListener
private TextToSpeech repeatTTS;
Button btnspeakout;
EditText edtTexttoSpeak;
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.speakout);
btnspeakout = (Button) findViewById(R.id.btnspeakout);
edtTexttoSpeak = (EditText) findViewById(R.id.edtTexttoSpeak);
repeatTTS = new TextToSpeech(this, this);
btnspeakout.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
repeatTTS.speak(edtTexttoSpeak.getText().toString(),
TextToSpeech.QUEUE_FLUSH, null);
);
@Override
public void onInit(int arg0)
// TODO Auto-generated method stub
