import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

                        }
                    });
                    break;
                case TextToSpeech.Engine.CHECK_VOICE_DATA_BAD_DATA://需要的语音数据已损坏
                case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_DATA://缺少需要语言的语音数据
                case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_VOLUME://缺少需要语言的发音数据
                    //跳转语音下载
                    Intent installIntent = new Intent();
                    installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                    startActivity(installIntent);
                    break;
                case TextToSpeech.Engine.CHECK_VOICE_DATA_FAIL:
                default:
                    Log.e(TAG, "Got a failure.");
            }
        }
    }

}

上面的不行，就下面的，只要安装了支持tts的程序软件都会返回true



import android.content.Intent;
import android.speech.tts.TextToSpeech;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d(TAG, "USE tts : "+ttsIsWork());

    }
    boolean ttsiswork;
    TextToSpeech speaker;
    public boolean ttsIsWork() {
        ttsiswork= true;
        speaker=new TextToSpeech(MainActivity.this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (speaker==null) ttsiswork =false;
            }
        });
        return ttsiswork;
    }
}
