python - Pyttxs3 文件中的 JackShmReadWritePtr 错误

Question

import pyttsx3
engine = pyttsx3.init() # object creation

""" RATE"""
rate = engine.getProperty('rate')   # getting details of current speaking rate
print (rate)                        #printing current voice rate
engine.setProperty('rate', 125)     # setting up new voice rate


"""VOLUME"""
volume = engine.getProperty('volume')   #getting to know current volume level (min=0 and max=1)
print (volume)                          #printing current volume level
engine.setProperty('volume',1.0)    # setting up volume level  between 0 and 1

"""VOICE"""
voices = engine.getProperty('voices')       #getting details of current voice
#engine.setProperty('voice', voices[0].id)  #changing index, changes voices. o for male
engine.setProperty('voice', voices[1].id)   #changing index, changes voices. 1 for female

engine.say("Hello World!")
engine.say('My current speaking rate is ' + str(rate))
engine.runAndWait()
engine.stop()

我正在使用 pyttsx3 库来创建我正在制作的聊天机器人，并且我在单独的文件上运行了此测试，现在遇到了错误...

我研究了如何解决这个问题，但我无法理解每个人在说什么，那么我该如何解决这个问题？谢谢! ...................................................... ...................................................... ...................................................... ...................................................... ...................................................... ......(这是为了反对我无法在没有太多文字的情况下发布那么多代码)

Answer 1

该错误表明jack 服务器存在问题。首先，我会尝试重新启动音频系统并查看它是否有效:

pulseaudio --kill  
jack_control start
jack_control exit  
pulseaudio --start

如果jackd不会死，就杀死它。
