如何在python线程中使用pyttsx

Question

我正在与pyttsx3合作进行文字转语音。我意识到我可以在一个线程中使用它（或者我做错了什么）。你知道为什么吗？

代码示例：

from threading import Thread
import pyttsx3

def myfunc():
  engine = pyttsx3.init()
  engine.say("ok")
  engine.runAndWait()

t = Thread(target=myfunc)
t.start()

错误：

 File "/usr/local/Cellar/python3/3.6.4/Frameworks/Python.framework/Versions/3.6/lib/python3.6/threading.py", line 916, in _bootstrap_inner
    self.run()
  File "/usr/local/Cellar/python3/3.6.4/Frameworks/Python.framework/Versions/3.6/lib/python3.6/threading.py", line 864, in run
    self._target(*self._args, **self._kwargs)
  File "test.py", line 9, in myfunc
    engine.runAndWait() #blocks
  File "/usr/local/lib/python3.6/site-packages/pyttsx3/engine.py", line 188, in runAndWait
    self.proxy.runAndWait()
  File "/usr/local/lib/python3.6/site-packages/pyttsx3/driver.py", line 204, in runAndWait
    self._driver.startLoop()
  File "/usr/local/lib/python3.6/site-packages/pyttsx3/drivers/nsss.py", line 33, in startLoop
    AppHelper.runConsoleEventLoop()
  File "/usr/local/lib/python3.6/site-packages/PyObjCTools/AppHelper.py", line 241, in runConsoleEventLoop
    nextfire = nextfire.earlierDate_(soon)
AttributeError: 'NoneType' object has no attribute 'earlierDate_'

错误似乎是它不在osx上的线程中运行。以下是一些可能效果很好的示例：

如果您只需要将文本转换为语音，则可以使用os.system('say %s')：

import os
def myfunc():
  os.system('say ok')

gTTS或谷歌的TextToSpeech引擎，支持64种语言，包括意大利语。用法：

from gtts import gTTS
import os
tts = gTTS(text='Good morning', lang='it')
tts.save("good.mp3")
os.system("mpg321 good.mp3")
