python 利用pyttsx3文字转语音
# -*- coding: utf-8 -*-
import pyttsx3
engine = pyttsx3.init()
with open("all.txt",'r',encoding='utf-8') as f:
while 1:
line = f.readline()
print(line, end = '')
engine.say(line)
engine.runAndWait()
import pyttsx3
with open('all.txt','r',encoding='utf-8') as f:
line = f.read()#文件不大,一次性读取
engine = pyttsx3.init()
#调整频率
rate = engine.getProperty('rate')
engine.setProperty('rate', rate-50)
# 调整音量
volume = engine.getProperty('volume')
engine.setProperty('volume', volume+0.25)
engine.say(line)
engine.runAndWait()
安装
pip install pyttsx3
语音引擎工厂
类似于设计模式中的“工厂模式”,pyttsx3通过初始化来获取语音引擎。当我们第一次调用init操作的时候,会返回一个pyttsx3的engine对象,再次调用的时候,如果存在engine对象实例,就会使用现有的,否则再重新创建一个。
pyttsx.init([driverName : string, debug : bool]) → pyttsx.Engine
从方法声明上来看,第一个参数指定的是语音驱动的名称,这个在底层适合操作系统密切相关的。如下:
1.drivename:由pyttsx3.driver模块根据操作系统类型来调用,默认使用当前操作系统可以使用的最好的驱动
- sapi5 - SAPI5 alt="在这里插入图片描述" />
元数据音调在pyttsx3.voice.Voice中,处理合成器的发音。
age
发音人的年龄,默认为None
gender
以字符串为类型的发音人性别: male, female, or neutral.默认为None
id
关于Voice的字符串确认信息. 通过 pyttsx3.engine.Engine.setPropertyValue()来设置活动发音签名. 这个属性总是被定义。
languages
发音支持的语言列表,如果没有,则为一个空的列表。
name
发音人名称,默认为None.
