本文主要講解如何使用python來實現將文字轉為語音，以一個小例子為例，寫了一下用pyTTS來朗讀本地方件或線上朗讀RFC文件，當然也可以修改一下，做成線上朗讀新聞之類的，另本來想實現一個讀中文小說的小程式，目前沒有發現對中文支援得非常好的，且是免費的語音處理引擎，只能使用TTS實現一個英文的了，就當是用來練習聽力了。

  1、準備:

       b.  下載SpeechSDK51：下載

       c.  下載SpeechSDK51 patch，支援中文和日文，本例沒有使用，下載。

 2、實現：

  程式碼:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

#程式說明：此程式實現了通過TTS將文字內容讀出來，提供了兩種方式，一種是讀本地文字檔案，
#另一種方式為線上讀RFC文件，要屬入rfc編號，會將其內容逐行讀出來列印到終端，其中音量
#大小，語速，朗讀者可能過配置檔案來設定，測試了下基本還算清楚，發現免費的TTS引擎對中文
#的支援均不是很好，所以本程式暫時沒有處理對中文檔案的閱讀

China says it condemns all acts of violence against innocent civilians



BEIJING - China's negative vote on a draft resolution on Syria at the United Nations General Assembly on Thursday was consistent with China's independent foreign policy of peace and in the best interests of the Syrian situation, officials and experts said. 



China opposes armed intervention or forcing a so-called regime change in Syria, China's deputy permanent representative to the UN Wang Min said in explanatory remarks.



"We condemn all acts of violence against innocent civilians and urge the government and all political factions of Syria to immediately and fully end all acts of violence, and quickly restore stability and the normal social order," Wang said.
