Text zu Sprache (TTS) -Android

Question

Ich bin neu auf der Android-Plattform. Jetzt arbeite ich an TTS(Text to Speech). Wenn ich den Text in einem TextArea eingeben und ich möchte, dass es in Sprache konvertiert wird, wenn ich auf die Schaltfläche "Sprechen" klicke.

Kann mir jemand helfen?

Answer 1

Text zu Sprache ist in Android 1.6+ integriert. Hier ist ein einfaches Beispiel, wie es gemacht wird.

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

Here are instructions, wie Beispielcode aus dem Android SDK-Manager zum Download:

1. Starten Sie das Android SDK-Manager.

   a. Doppelklicken Sie unter Windows auf die Datei SDK Manager.exe im Stammverzeichnis des Android SDK-Verzeichnisses.

   b. Öffnen Sie unter Mac oder Linux ein Terminal für das Verzeichnis tools/im Android SDK, und führen Sie dann android sdk aus.

2. Erweitern Sie die Liste der Pakete für die neueste Android-Plattform.

3. Wählen und laden Sie Samples für SDK. Wenn der Download abgeschlossen ist, können Sie den Quellcode für alle Proben an diesem Ort finden:

/sdk/samples/Android-Version/

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

Answer 4

Versuchen Sie dies, es ist einfach: ** 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> 

und Ihre 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 
} 
}
