所以我用Python做了一个聊天机器人/虚拟助手，我在为Python搜索文本到语音引擎，发现了pyttsx，我用pip下载了它（如下所示：sudo pip install pyttsx）（顺便说一句，我使用的是Linux）。我使用的是Python 2.7（我尝试使用Python 3.5，给了我同样的错误）。我导入了它，它工作，但当我把（正如本教程"告诉我"到https://pythonspot.com/en/speech-engines-with-python-tutorial/）engine = pyttsx.init()。
代码如下所示：

import pyttsx
engine = pyttsx.init()
engine.say('Hello There')
engine.runAndWait()

这是我得到的错误：

Traceback (most recent call last):
  File "/home/theshoutingparrot/Desktop/Programming/Python/Bots/A.I/speechtotext.py", line 2, in <module>
    engine = pyttsx.init()

    return self._dlltype(name)

    self._handle = _dlopen(self._name, mode)
OSError: libespeak.so.1: cannot open shared object file: No such file or directory

任何帮助都是好的，或者如果你能帮忙的话，提前建议一个其他的文本到语音引擎。
