1、python语音识别可以使用speech_recognition

安装pip install speech_recognition

识别代码：

# -*- coding: utf-8 -*-
# /usr/bin/python
import speech_recognition as sr
r = sr.Recognizer()    #调用识别器
test = sr.AudioFile("/data/wwwroot/default/asset/voice.flac")   #导入语音文件
with test as source:       
    audio = r.record(source)
type(audio)
c=r.recognize_sphinx(audio, language='zh-cn')     #识别输出
print(c)

在这个文件夹中添加进入刚刚解压的文件，需要注意：把解压出来的zh_cn.cd_cont_5000文件夹重命名为acoustic-model、zh_cn.lm.bin命名为language-model.lm.bin、zh_cn.dic中dic改为dict格式。

2、文字转语音，安装pyttsx3

 pip install pyttsx3

daiam ru

import pyttsx3

def Word_VR(word, speed=50):
    engine = pyttsx3.init()
    # 设置新的语音音量, 音量最小为 0, 最大为 1
    engine.setProperty('volume', 1)
    voices = engine.getProperty('voices')
    # 改变语速  范围为0-200   默认值为200
    rate = engine.getProperty('rate')
    engine.setProperty('rate', rate+ speed)
    #voices[0]是男声，voices[1]是女生
    engine.setProperty('voice', voices[0].id)
    # engine.setProperty("voice", "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens\TTS_MS_ZH - CN_HUIHUI_11.0")
    engine.say(word)
    engine.runAndWait()

if __name__=='__main__':
    Word_VR("你好，小辰", 60)
