+### 01.TTS简单的描述
+- TTS全称Text  To Speech ，是文本转语音服务
+
+
+
+### 02.TTS简单的案例
+#### 2.1 初始化tts
+- 代码如下所示
+    ```
+    textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
+        @Override
+        public void onInit(int status) {
+            if (!mReady  && (TextToSpeech.SUCCESS == status) && textToSpeech != null) {
+                VideoLogUtils.i("Initialize TTS success");
+                //获取locale
+                final Locale locale = mContext.getApplicationContext()
+                        .getResources().getConfiguration().locale;
+                if (locale != null) {
+                    VideoLogUtils.i("tts isLanguageAvailable " + mTts.isLanguageAvailable(locale) +
+                            "; variant is " + locale.getVariant() +
+                            "; locale is " + locale + " ; country  is " + locale.getCountry());
+                }
+                //设置朗读语言
+                int setLanguage = this.textToSpeech.setLanguage(null != locale ? locale : Locale.getDefault());
+                switch (setLanguage) {
+                    case TextToSpeech.LANG_MISSING_DATA:
+                        VideoLogUtils.i("TTS set language: Language missing data");
+                        break;
+                    case TextToSpeech.LANG_NOT_SUPPORTED:
+                        VideoLogUtils.i("TTS set language: Language not supported");
+                        break;
+                    case TextToSpeech.LANG_AVAILABLE:
+                        VideoLogUtils.i("TTS set language: Language available");
+                        break;
+                    case TextToSpeech.LANG_COUNTRY_AVAILABLE:
+                        VideoLogUtils.i("TTS set language: Language country available");
+                        break;
+                    case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE:
+                        VideoLogUtils.i("TTS set language: Language country var available");
+                        break;
+                    default:
+                        VideoLogUtils.i("TTS set language: Unknown error");
+                        break;
+                }
+            } else if (TextToSpeech.ERROR == status) {
+                VideoLogUtils.i("Initialize TTS error");
+            } else {
+                VideoLogUtils.i("Initialize TTS error");
+            }
+        }
+    });
+    ```
+
+
+#### 2.2 如何进行初始化
+- 如何进行播放？
+    ```
+    textToSpeech.speak(tts, TextToSpeech.QUEUE_FLUSH, null);
+    ```
+- 循环播放语音
+    - 想让他报个2-3遍或者循环播报的时候，我们来试一下
+    ```
+    for (int i=0 ; i<5 ; i++){
+        textToSpeech.speak("简单播放tts，"+i, TextToSpeech.QUEUE_FLUSH, null);
+    }
+    ```
+    - 简单的不行，但是问题来了，一段长的文字他只播报前面几个字，然后又重新开始播报。
+    - 这是因为textToSpeech.speak(tts, TextToSpeech.QUEUE_FLUSH, null);这个方法会自动关闭掉上面一个播报的内容，从而进行新一轮的播报。
+- 播放完成后再播放
+    - 要等上一条播报完整了再进行播报，该如何操作呢？那么可以TTS有 isSpeaking() 这个方法
+    ```
+    for (int i=0 ; i<5 ; i++){
+        if (!textToSpeech.isSpeaking()){
+            textToSpeech.speak("简单播放tts，"+i, TextToSpeech.QUEUE_FLUSH, null);
+        }
+    }
+    ```
+    - 这样就可以播全了嘛？ 非也，for循环飞快的跑只要发现在speaking那么直接跳过开始走下一个i
+- 如何正确循环播放
+    ```
+    for (int i=0 ; i<5 ; i++){
+        textToSpeech.speak("简单播放，"+i, TextToSpeech.QUEUE_ADD, null);
+    }
+    ```
+    - 这样就相当于在一个消息队列然后进行循环的播报。
+
+
+### 03.TTS播报监听处理
+- 关于监听tts状态如下所示：
+    ```
+    private final class OnCompleteListener extends UtteranceProgressListener {
+    
+        OnCompleteListener() {
+    
+        }
+    
+        /**
+         * 播放完成。这个是播报完毕的时候 每一次播报完毕都会走
+         * @param utteranceId                       话语id
+         */
+        @Override
+        public void onDone(final String utteranceId) {
+            VideoLogUtils.i("TTSPlayer OnCompleteListener onDone");
+            onCompleted();
+        }
+    
+        /**
+         * 播放异常
+         * @param utteranceId                       话语id
+         */
+        @Override
+        public void onError(final String utteranceId) {
+            VideoLogUtils.i("TTSPlayer OnCompleteListener onError");
+            stop();
+            onError("TTSPlayer has play fail : " + utteranceId);
+            onCompleted();
+        }
+    
+        /**
+         * 播放开始。这个是开始的时候。是先发声之后才会走这里
+         * 调用isSpeaking()方法在这为true
+         * @param utteranceId                       话语id
+         */
+        @Override
+        public void onStart(final String utteranceId) {
+    
+        }
+    }
+    ```

+
+### 关于log日志
+- log 方法内存开销过大。建议这个方法 建议 Debug 进入执行 ，但是正是包不执行，因为 object 会进行字符串+拼接，产生大量内存对象。
+```
+public static void d(Object object){
+    //这个方法 建议 Debug 进入执行 ，但是正是包不执行，因为 object 会进行字符串+拼接，产生大量内存对象。
+    //Log.d(TAG, object.toString());
+    Log.d(TAG, " log : " + object);
+}
