文本到语音(TTS)-Android

小开

最佳答案

Android 1.6 + 内置了文本对话功能，下面是一个简单的例子。

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

下面是关于如何从 Android SDK Manager 下载示例代码的说明:

启动 Android SDK 管理器。

在 Windows 上，双击 Android SDK 目录根目录下的 SDK Manager.exe 文件。

在 Mac 或 Linux 上，打开 Android SDK 中的 tools/目录的终端，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，您可以在这个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)

试试这个，很简单: Xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#3498db"
android:weightSum="1"
android:orientation="vertical" >
<TextView
android:id="@+id/txtheader"
android:layout_width="match_parent"
android:layout_height="0dp"
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_width="match_parent"
android:layout_weight=".5"
android:background="#fff"
android:textColor="#2c3e50"
android:text="Hi there!!!"
android:padding="5dp"
android:gravity="top|left"
android:layout_height="0dp"/>
<Button
android:id="@+id/btnspeakout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=".1"
android:background="#e74c3c"
android:textColor="#fff"
android:text="SPEAK OUT"/>
</LinearLayout>

还有你的 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

一个快速测试 TTS 系统的简单例子:

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不都将英语设置为默认语言，因此单词的发音将是错误的。但是对于测试一般的 TTS 来说，这个代码片段就足够了

// variable declaration
TextToSpeech tts;


// TextToSpeech initialization, must go within the onCreate method

int result = tts.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA ||
result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Lenguage not supported");
}
} else {
Log.e("TTS", "Initialization failed");
}
}
});


// method call
public void buttonSpeak().setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
speak();
}
});
}


private void speak() {
tts.speak("Text to Speech Test", TextToSpeech.QUEUE_ADD, null);
}


@Override
public void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
