python的语音识别

首先基于python36
安装模块

pip install pyttsx3
pip install PocketSphinx
pip install SpeechRecognition
pip install comtypes

利用txt文件创建语音文件

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

接着利用之前创建的demo_audio.wav的语音文件

import speech_recognition as sr 
audio_file='demo_audio.wav' 
r=sr.Recognizer() 
with sr.AudioFile(audio_file) as source: 
    audio =r.record(source) 
try: # print('文本内容：',r.recognize_sphinx(audio,language="zh_CN")) 
    print('文本内容：',r.recognize_sphinx(audio)) 
except Exception as e: 
       ``print(e)
由于pyhton的语音识别不识别中文可到该网站下载需要的模块
