安装

pip install pyttsx3

如果您遇到安装错误，请确保首先使用以下命令升级您的 Wheel 版本：
pip install --upgrade wheel

Linux 安装要求：
如果您使用的是 linux 系统并且语音输出不起作用，那么：

安装 espeak 、 ffmpeg 和 libespeak1 如下图所示：

 sudo apt update && sudo apt install espeak ffmpeg libespeak1

朗读文本示例：

import pyttsx3
engine = pyttsx3.init()
engine.say('Sally sells seashells by the seashore.')
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

将语音保存到文件

import pyttsx3
engine = pyttsx3.init()
engine.save_to_file('Hello World' , 'test.mp3')
engine.runAndWait()

监听事件

import pyttsx3
def onStart(name):
   print 'starting', name
def onWord(name, location, length):
   print 'word', name, location, length
def onEnd(name, completed):
   print 'finishing', name, completed
engine = pyttsx3.init()
engine.connect('started-utterance', onStart)
engine.connect('started-word', onWord)
engine.connect('finished-utterance', onEnd)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

打断话语

import pyttsx3
def onWord(name, location, length):
   print 'word', name, location, length
   if location > 10:
      engine.stop()
engine = pyttsx3.init()
engine.connect('started-word', onWord)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

改变声音

engine = pyttsx3.init()
voices = engine.getProperty('voices')
for voice in voices:
   engine.setProperty('voice', voice.id)
   engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

改变语速

engine = pyttsx3.init()
rate = engine.getProperty('rate')
engine.setProperty('rate', rate+50)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

改变音量

engine = pyttsx3.init()
volume = engine.getProperty('volume')
engine.setProperty('volume', volume-0.25)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

运行驱动程序事件循环

engine = pyttsx3.init()
def onStart(name):
   print 'starting', name
def onWord(name, location, length):
   print 'word', name, location, length
def onEnd(name, completed):
   print 'finishing', name, completed
   if name == 'fox':
      engine.say('What a lazy dog!', 'dog')
   elif name == 'dog':
      engine.endLoop()
engine = pyttsx3.init()
engine.connect('started-utterance', onStart)
engine.connect('started-word', onWord)
engine.connect('finished-utterance', onEnd)
engine.say('The quick brown fox jumped over the lazy dog.', 'fox')
engine.startLoop()

使用外部事件循环

engine = pyttsx3.init()
engine.say('The quick brown fox jumped over the lazy dog.', 'fox')
engine.startLoop(False)
# engine.iterate() must be called inside externalLoop()
externalLoop()
engine.endLoop()

打印好玩的

import cowsay
print(dir(cowsay))
cowsay.dragon('┗|｀O′|┛ 嗷~~')
