public class MyTextToSpeech implements TextToSpeech.OnInitListener {
    /**
     * 语音
     */
    private TextToSpeech mTextToSpeech;//TTS对象
    private ConcurrentLinkedQueue mBufferedMessages;//消息队列
    private boolean mIsReady;//标识符
    private Context context;
    private String text;

    public MyTextToSpeech(Context context, String text) {
        mBufferedMessages = new ConcurrentLinkedQueue();//实例化队列
        mTextToSpeech = new TextToSpeech(context, this);//实例化TTS
        this.context = context;
        this.text = text;
    }

    @Override
    public void onInit(int status) {
        Log.i("TextToSpeechDemo", String.valueOf(status));
        if (status == TextToSpeech.SUCCESS) {
            int result = this.mTextToSpeech.setLanguage(Locale.CHINA);//设置识别语音为中文
            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
                long l[] = {100, 500, 100, 500};
                vibrator.vibrate(l, -1);
                Toast.makeText(context, "数据丢失或不支持", Toast.LENGTH_SHORT).show();
            }
            synchronized (this) {
                this.mIsReady = true;//设置标识符为true
//                for (String bufferedMessage : this.mBufferedMessages) {
//                    speakText(bufferedMessage);//读语音
//                }
                speakText(text);//读语音
                this.mBufferedMessages.clear();//读完后清空队列
            }
        }
    }

    //释放资源
    public void release() {

            this.mTextToSpeech.shutdown();
            this.mIsReady = false;
        }
    }

    //更新消息队列，或者读语音
    public void notifyNewMessage(String lanaugh) {
        String message = lanaugh;
        synchronized (this) {
            if (this.mIsReady) {

            } else {
                this.mBufferedMessages.add(message);
            }
        }
    }

    //读语音处理
    private void speakText(String message) {
        Log.i("BloodPressureBluetooth1", message);
        HashMap params = new HashMap();
        params.put(TextToSpeech.Engine.KEY_PARAM_STREAM, "STREAM_NOTIFICATION");//设置播放类型（音频流类型）
        this.mTextToSpeech.speak(message, TextToSpeech.QUEUE_ADD, params);//将这个发音任务添加当前任务之后
        this.mTextToSpeech.playSilence(100, TextToSpeech.QUEUE_ADD, params);//间隔多长时间
    }
