python pyttsx3库将文本（text）转换为语音

利用python中的一些库，可以实现文本转音频的功能。这时候，电脑将作为一个AI语音播报助手，直接将输入的文字内容读给你听。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

这里举一个简单的例子。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

1、 首先安装一个pyttsx3库。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

pip install pyttsx3文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

2、 导入需要的库文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

import pyttsx3 as pts文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

pt = pts.init() # 初始化文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

pt.say("Hello. Nice to meet you.") # 设置语音"Hello. Nice to meet you."文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

pt.runAndWait() #使电脑读出语音文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

如果电脑扬声器正常打开的话，就能听到语音了。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

3、使用.setProperty()函数设置语音参数，.getProperty(）获取参数值。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

定义一个函数，根据目前的时间发出不同的问候语。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

import pyttsx3文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

import datetime文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

engine=pyttsx3.init('sapi5')文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

voices=engine.getProperty('voices')文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

rate= engine.getProperty('rate')文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

volume= engine.getProperty('volume')文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

engine.setProperty('voice',voices[1].id) #voices[0]表示男声，voices[1]表示女声。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

engine.setProperty('rate',100) #rate设置语速,默认值200。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

engine.setProperty('volume',0.5) # volume设置音量比例，取值在0到1之间。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

def speak(text):文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

engine.say(text)文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

    engine.runAndWait()文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

def wishMe():文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

    hour=datetime.datetime.now().hour文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

    if hour>=0 and hour<12:文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      speak("Hello,Good Morning")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      print("Hello,Good Morning")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

    elif hour>=12 and hour<18:文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      speak("Hello,Good Afternoon")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      print("Hello,Good Afternoon")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

    else:文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      speak("Hello,Good Evening")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

      print("Hello,Good Evening")文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html

注意在".say"后面加上".runAndWait()"。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/47034.html
