文本到语音（TTS） – 安卓

我是新来的android平台。 现在我正在研究TTS(Text to Speech) 。如果我在TextArea中input文本，并且希望在单击发言button时将其转换为语音。

谁能帮我吗？

Answer 1

文本到语音是Android 1.6+内置的。 这里是一个简单的例子，如何做到这一点。

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

以下是有关如何从Android SDK Manager下载示例代码的说明 ：

1. 启动Android SDKpipe理器。

   一个。 在Windows上，双击Android SDK目录根目录下的SDK Manager.exe文件。

   湾 在Mac或Linux上，打开terminal到Android SDK中的tools /目录，然后执行android sdk。

2. 展开最新Android平台的软件包列表。

3. select并下载SDK的Samples。 下载完成后，您可以在此位置find所有示例的源代码：

/ SDK /样品/ Android的版本/

 (ie \android-sdk-windows\samples\android-16\ApiDemos\src\com\example\android\apis\app\TextToSpeechActivity.java)

 package com.example.texttospeech; import java.util.Locale; import android.os.Bundle; import android.app.Activity; import android.content.SharedPreferences.Editor; import android.speech.tts.TextToSpeech; import android.util.Log; import android.view.Menu; import android.view.View; import android.widget.EditText; public class MainActivity extends Activity { String text; EditText et; TextToSpeech tts; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); et=(EditText)findViewById(R.id.editText1); tts=new TextToSpeech(MainActivity.this, new TextToSpeech.OnInitListener() { @Override public void onInit(int status) { // TODO Auto-generated method stub if(status == TextToSpeech.SUCCESS){ int result=tts.setLanguage(Locale.US); if(result==TextToSpeech.LANG_MISSING_DATA || result==TextToSpeech.LANG_NOT_SUPPORTED){ Log.e("error", "This Language is not supported"); } else{ ConvertTextToSpeech(); } } else Log.e("error", "Initilization Failed!"); } }); } @Override protected void onPause() { // TODO Auto-generated method stub if(tts != null){ tts.stop(); tts.shutdown(); } super.onPause(); } public void onClick(View v){ ConvertTextToSpeech(); } private void ConvertTextToSpeech() { // TODO Auto-generated method stub 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); } } <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <Button android:id="@+id/button1" style="?android:attr/buttonStyleSmall" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="177dp" android:onClick="onClick" android:text="Button" /> <EditText android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@+id/button1" android:layout_centerHorizontal="true" android:layout_marginBottom="81dp" android:ems="10" > <requestFocus /> </EditText> </RelativeLayout>

尝试这个，它的简单：** speakout.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> 

和你的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 } }
