pyttsx

安装 pyttsx库：pip install pyttsx3  

import pyttsx3 as px3
 
speak = px3.init()  # 初始化语音引擎
rate = speak.getProperty('rate')
print('语速：%s' % rate)  # 默认：200
volume = speak.getProperty('volume')
print('音量：%s' % volume)  # 默认：1.0
speak.setProperty('rate',100)  # 设置语速
speak.setProperty('volume',2.0)  # 设置音量
speak.say('合家欢乐啊')
speak.runAndWait()
speak.stop()

SAPI

from win32com.client import Dispatch
 
text = '大风一日同风起，扶摇直上九万里'
speak = Dispatch('SAPI.SpVoice')
speak.Speak(text)
del speak

SpeechLib

使用SpeechLib，可以从文本文件中获取输入，再将其转换为语音。

安装pip install comtypes

from comtypes.client import CreateObject as ct
from comtypes.gen import SpeechLib
 
engine = ct('SAPI.SpVoice')
stream = ct('SAPI.SpFileStream')
 
infile = 'shiju.txt'
outfile = 'luming_audio.wav'
stream.Open(outfile, SpeechLib.SSFMCreateForWrite)
engine.AudioOutputStream = stream
with open(infile, 'r', encoding='utf-8') as f:
    theText = f.read()
engine.speak(theText)
stream.close()

PocketSphinx

一个轻量级的语音识别引擎，用于语音转换文本的开源API。

安装库：pip install SpeechRecognition

              pip install pocketsphinx 

import speech_recognition as sr
 
audio_file = 'luming_audio.wav'
r = sr.Recognizer()
with sr.AudioFile(audio_file) as source:
    audio = r.record(source)
try:
    # print(r.recognize_sphinx(audio))  # 不指定language参数时，默认识别英文en-US 
    print(r.recognize_sphinx(audio, language='zh-CN'))
except Exception as e:
    print(e)

默认没有汉语包，使用时报错missing PocketSphinx language model parameters directory: "E:\python\Lib\site-packages\speech_recognition\pocketsphinx-data\zh-CN"，需要下载：CMU Sphinx - Browse /Acoustic and Language Models at SourceForge.net

下载后的包解压后修改名称为：zh-CN，并将其放在英文包en-US同目录下

 修改zh-CN中的文件名和en-US中的一样

修改后

实现了转换，就是效果不理想
