Answer 1

Prueba 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: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>

Y tu 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
}
}

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);

Más información: http://android-developers.blogspot.com/2009/09/introduction-to-text-to-speech-in.html

Aquí hay instrucciones sobre cómo descargar código de muestra desde el Administrador de Android SDK:

1. Inicie el Administrador de Android SDK.

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

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

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

3. Seleccione y descargue Muestras para SDK. Cuando se complete la descarga, puede encontrar el código fuente para todas las muestras en esta ubicación:

/ sdk / samples / android-version /

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

Answer 3

Un ejemplo minimalista para probar rápidamente el sistema TTS:

private TextToSpeech textToSpeechSystem;
@Override
protected void onStart() {
super.onStart();
textToSpeechSystem = new TextToSpeech(this, ttsInitResult -> {
if (TextToSpeech.SUCCESS == ttsInitResult) {
String textToSay = "Hello world, this is a test message!";
textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
}
});
}

Si no usa mensajes localizados, textToSpeechSystem.setLanguage(..) es importante, ya que es posible que sus usuarios no tengan todos los idiomas en inglés como idioma predeterminado, por lo que la pronunciación de las palabras será incorrecta. Pero para probar TTS en general, este fragmento es suficiente
