pyttsx3是Python中的文本到语音转换库。与其他库不同，它可以脱机工作，并且与Python 2和3兼容。

安装指令

pip3 install  pyttsx3

高阶使用

import pyttsx3
engine = pyttsx3.init() # object creation
""" 把语音存储到文件 """
engine.save_to_file("Hello World!!!",'~/abc.mp3')

"""更改速率"""
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，数值越大，语速越快


"""更改音量"""
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

"""更改音色"""
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.runAndWait()
engine.stop()
