TextToSpeech核心程式碼:

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        mBinding.setOnClick(this);
        mTextToSpeech = new TextToSpeech(this,this);
    }

 

    private void speakOut() {
        if (mTextToSpeech!= null && !mTextToSpeech.isSpeaking()){
//            Bundle bundle = new Bundle();
//            bundle.putFloat(TextToSpeech.Engine.KEY_PARAM_VOLUME,1.0f);
            //朗讀，注意這裡三個引數的added in API level 4   四個引數的added in API level 21
//            mTextToSpeech.speak(mBinding.editText.getText().toString(),TextToSpeech.QUEUE_FLUSH,null);
            mTextToSpeech.speak(mBinding.editText.getText().toString(),TextToSpeech.QUEUE_FLUSH,null,"");
        }
    }

    /**
     * 初始化語音播放
     * @param status
     */
    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS){
            // 設定音調,1.0是常規
            mTextToSpeech.setPitch(1.0f);
            //設定語速 ，預設1.0正常語速
            mTextToSpeech.setSpeechRate(1.0f);
            int result = mTextToSpeech.setLanguage(Locale.CHINA);
            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED){
                Toast.makeText(this,"資料丟失或不支援",Toast.LENGTH_SHORT).show();
            }
        }

            }
       }

       @Override
       public void onEvent(int i, int i1, int i2, Bundle bundle) {
           // 以下程式碼用於獲取與雲端的會話id，當業務出錯時將會話id提供給技術支援人員，可用於查詢會話日誌，定位出錯原因
           // 若使用本地能力，會話id為null
       }
   };


    @Override
    public void onInit(int i) {
        if (i != ErrorCode.SUCCESS){
            return;//初始化失敗
        }
        mSynthesizer.setParameter(SpeechConstant.ENGINE_MODE, SpeechConstant.MODE_MSC);
        mSynthesizer.setParameter(SpeechConstant.ENGINE_TYPE, SpeechConstant.TYPE_LOCAL);
        mSynthesizer.setParameter(ResourceUtil.TTS_RES_PATH, getResourcePath());

程式碼較為簡單,有不足之處大家可以留言交流
