                pool.play(index, 1, 1, 0, 0, 1);

                int index = (Integer) listPool.get(flag);
                pool.play(index, 1, 1, 0, 0, 1);
            }
        }else{
            System.out.println("===========語音提示關閉");
        }
    }
}

使用步驟：

1初始化

在Acitvity或fragment中的onCreate方法

 SoundUtils.getInstance().initPool(this);

2 呼叫

 SoundUtils.getInstance().playVoice(1);

文字轉語音的工具

生成的音訊檔案，放到android專案中的res/raw目錄下
