我正在尝试为 android 实现 TTS 应用程序。这是我到目前为止编写的代码:

import android.app.Activity;
import android.content.Intent;
import android.view.View.OnClickListener;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.Locale;

public class AlarmActivity extends Activity implements OnClickListener, TextToSpeech.OnInitListener {

    private TextToSpeech mTts;
    private static final String TAG = "TextToSpeechDemo";
    private static final int MY_DATA_CHECK_CODE = 1234;
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.alarm);

        Button btnAdd = (Button) findViewById(R.id.btnAdd);
        btnAdd.setOnClickListener(this);
        btnAdd.setEnabled(false);

        TextView txt = (TextView) findViewById(R.id.txt);
        txt.setText("OnCreate");

        // Fire off an intent to check if a TTS engine is installed
        Intent checkIntent = new Intent();
        checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
    }
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        TextView txt = (TextView) findViewById(R.id.txt);
        if (requestCode == MY_DATA_CHECK_CODE)
        {
            if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
            {
                // success, create the TTS instance
                txt.setText("Done result");
                mTts = new TextToSpeech(this, this);
                mTts.setLanguage(Locale.US);
                Button btnAdd = (Button) findViewById(R.id.btnAdd);
                btnAdd.setEnabled(true);

            }
            else
            {
                txt.setText("Missing");
                // missing data, install it
                Intent installIntent = new Intent();
                installIntent.setAction(
                        TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installIntent);
            }
        }
    }

    @Override
    public void onDestroy()
    {
        // Don't forget to shutdown!
        if (mTts != null)
        {
            mTts.stop();
            mTts.shutdown();
        }
        super.onDestroy();
    }

    @Override
    public void onClick(View v) {

        TextView txt = (TextView) findViewById(R.id.txt);
                txt.setText("Click");

        String myText1 = "Did you sleep well?";
        String myText2 = "I hope so, because it's time to wake up.";
        mTts.speak(myText1, TextToSpeech.QUEUE_FLUSH, null);
        mTts.speak(myText2, TextToSpeech.QUEUE_ADD, null);
    }
    @Override
    public void onInit(int status) {
        TextView txt = (TextView) findViewById(R.id.txt);
        txt.setText("status 0");
        if (status == TextToSpeech.SUCCESS) {
                txt.setText("status 1");
            int result = mTts.setLanguage(Locale.US);
            if (result == TextToSpeech.LANG_MISSING_DATA ||
                result == TextToSpeech.LANG_NOT_SUPPORTED) {
                txt.setText("status 2");
            } else {
                Button btnAdd = (Button) findViewById(R.id.btnAdd);
                btnAdd.setEnabled(true);
                txt.setText("status 3");
            }
            } else {
            txt.setText("status 4");
            Log.e(TAG, "Could not initialize TextToSpeech.");
        }
    }
}

我的布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="5dp">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Alarms"
        android:id="@+id/txt" />
    <Button android:id="@+id/btnAdd"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="Say" />
</LinearLayout>

在 netbeans ADB 日志中，我可以看到以下内容:

很明显，我尝试输出的文本是从日志中发送的，但是我听不到手机发出任何声音。可能是什么问题？

最佳答案

这似乎是因为手机在 USB Debug模式下连接到计算机。禁用后，TTS 将完美运行!

关于Android - TTS 没有声音出来，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5203448/
