使用pyttsx的python文本到语音转换

Question

我想用我的树莓派来宣布一些文字。我已经安装了pyttsx，但无法使用它。我正在使用python2.7

我的程序：

import pyttsx
engine= pyttsx.init()
engine.setProperty('rate',70)
voices=engine.getProperty('voices')
for voice in voices:
    print "Using voice:", repr(voice)
    engine.setProperty('voice',voice.id)
    engine.say("Hello Hello Hello")
engine.runAndWait()

但是我得到了这个错误：

Traceback (most recent call last):
File "/home/pi/announce.py", line 2, in <module>
engine= pyttsx.init()
File "/usr/local/lib/python2.7/dist-packages/pyttsx-1.1-     py2.7.egg/pyttsx/__init__.py", line 39, in 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

Answer 1

这是因为您的系统上没有安装espeak。这就是为什么它给出错误的原因

libepeak.so.1错误:找不到这样的文件或目录。

尝试使用以下命令安装espeak：

sudo apt-get update && sudo apt-get install espeak

Answer 2

如果您使用的是Ubuntu，请使用以下代码

sudo apt install libespeak1

Answer 3

试试这个：：在Ubuntu/Linux终端上运行，

1.pip install pyttsx3，

2.sudo apt install libespeak1

您必须已成功安装。
