public class SpeechUtils {private Context context;
    private static final String TAG = "SpeechUtils";
    private static SpeechUtils singleton;

    private TextToSpeech textToSpeech; // TTS对象

    public static SpeechUtils getInstance(Context context) {if (singleton == null) {synchronized (SpeechUtils.class) {if (singleton == null) {singleton = new SpeechUtils(context);
                }}}return singleton;
    }public SpeechUtils(Context context) {t = context;
        textToSpeech = new TextToSpeech(context, new TextToSpeech.OnInitListener() {@Override
            public void onInit(int i) {if (i == TextToSpeech.SUCCESS) {textToSpeech.setLanguage(Locale.US);
                    // 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规
                    textToSpeech.setPitch(1.0f);
                    textToSpeech.setSpeechRate(1.0f);
                }}});
    }public void speakText(String text) {if (textToSpeech != null) {textToSpeech.speak(text,
                    TextToSpeech.QUEUE_FLUSH, null);
        }}}

调用&#Instance(getApplicationContext()).speakText("hello world");

注意：此类只针对英文的播报！！！
