Python调用pyttsx3实现离线文字转语音

pyttsx3是 Python 中的文本到语音的离线转换库。

安装依赖：

pip install pyttsx3

Linux 安装要求：

apt update && apt install espeak ffmpeg libespeak1

使用方式：

import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text")
engine.runAndWait()

带默认选项的朗读功能的单行用法

import pyttsx3
pyttsx3.speak("I will speak this text")

改变声音、语速和音量：

import pyttsx3
engine = pyttsx3.init() # object creation
 
# 语速
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
 
# 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
 
# 声音
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()
 
# 保存到文件
# On linux make sure that 'espeak' and 'ffmpeg' are installed
engine.save_to_file('Hello World', 'test.mp3')
engine.runAndWait()
