テキスト読み上げ（TTS）-Android
Androidプラットフォームを初めて使用します。現在、TTS(Text to Speech)に取り組んでいます。TextAreaにテキストを入力して、i話すボタンをクリックします。
誰も私を助けることができますか？
テキスト読み上げはAndroid 1.6+に組み込まれています。これを行う方法の簡単な例を次に示します。
TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

手順はこちら Android SDKマネージャーからサンプルコードをダウンロードする方法について：
Android SDK Managerを起動します。
a。 Windowsでは、Android SDKディレクトリのルートにあるSDK Manager.exeファイルをダブルクリックします。
b。 MacまたはLinuxでは、Android SDKのtools /ディレクトリへのターミナルを開き、Android sdk。
最新のAndroidプラットフォームのパッケージのリストを展開します。
- SDKのサンプルを選択してダウンロードします。ダウンロードが完了すると、次の場所ですべてのサンプルのソースコードを見つけることができます。

これを試してみてください：** speakout.xml：**

そして、あなたのSpeakOut.Java：

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

TTSシステムをすばやくテストするための最小限の例：
_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);
}
}
});
}
_ローカライズされたメッセージを使用しない場合、textToSpeechSystem.setLanguage(..)も重要です。これは、おそらくすべてのユーザーが英語をデフォルト言語として設定していないため、単語の発音が間違っているためです。しかし、一般にTTSをテストするには、このスニペットで十分です
