python 文本轉(zhuǎn)語音問題

import sys

reload(sys)
sys.setdefaultencoding('utf8')
import pyttsx
engine = pyttsx.init()
engine.say('hello world')
engine.runAndWait()

當(dāng)我使用pyttsy 嘗試轉(zhuǎn)換輸出語音是時(shí) 出現(xiàn)了這樣的錯(cuò)誤

C:\Python27\python.exe D:/python/ccc.py
Traceback (most recent call last):

請(qǐng)問這是什么原因呢？
