Texto a voz (TTS) -Android

Question

Soy nuevo en la plataforma de Android. Ahora estoy trabajando en TTS(Text to Speech). Si ingreso el texto en un área de texto y me gustaría que se convierta en voz cuando hago clic en el botón Hablar.

¿Alguien puede ayudarme?

Answer 1

Texto a voz está integrado en Android 1.6+. Aquí hay un ejemplo simple de cómo hacerlo.

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

Here are instructions sobre cómo descargar el código de ejemplo del SDK de Android Manager:

1. Lanzamiento del Gestor de Android SDK.

   a. En Windows, haga doble clic en el archivo SDK Manager.exe en la raíz del directorio Android SDK.

   b. En Mac o Linux, abra una terminal en el directorio tools/en el SDK de Android, luego ejecute sdk para Android.

2. Amplíe la lista de paquetes para la última plataforma de Android.

3. Seleccione y descargue Muestras para SDK. Cuando la descarga se haya completado, se puede encontrar el código fuente para todas las muestras en este lugar:

/SDK/muestras/android-version/

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

Pruebe esto, es simple: ** 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: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"

import android.speech.tts.TextToSpeech; 
import android.speech.tts.TextToSpeech.OnInitListener; 
import android.view.View;

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(),
