如下所示：

from win32com.client import constants
import os
import win32com.client
import pythoncom
 
speaker = win32com.client.Dispatch("SAPI.SPVOICE")
 
 
class SpeechRecognition:
 def __init__(self, wordsToAdd):
  self.speaker = win32com.client.Dispatch("SAPI.SpVoice")
  self.listener = win32com.client.Dispatch("SAPI.SpSharedRecognizer")
  self.context = self.listener.CreateRecoContext()
  self.grammar = self.context.CreateGrammar()
  self.grammar.DictationSetState(0)
  self.wordsRule = self.grammar.Rules.Add("wordsRule", constants.SRATopLevel + constants.SRADynamic, 0)
  self.wordsRule.Clear()
  [self.wordsRule.InitialState.AddWordTransition(None, word) for word in wordsToAdd]
  self.grammar.Rules.Commit()
  self.grammar.CmdSetRuleState("wordsRule", 1)
  self.grammar.Rules.Commit()
  self.eventHandler = ContextEvents(self.context)
  self.say("Started successfully")
 def say(self, phrase):
  self.speaker.Speak(phrase)
class ContextEvents(win32com.client.getevents("SAPI.SpSharedRecoContext")):
 def OnRecognition(self, StreamNumber, StreamPosition, RecognitionType, Result):
  newResult = win32com.client.Dispatch(Result)
  print("小伙子你在说 ", newResult.PhraseInfo.GetText())
  speechstr=newResult.PhraseInfo.GetText()
  if speechstr=="张三":
   speaker.Speak("zhaodahai love fengjie")
  elif speechstr=="你好":
   speaker.Speak("hello world")
  elif speechstr=="国庆快乐":
   speaker.Speak("Happy nationalday")
  elif speechstr=="新年快乐":
   speaker.Speak("happy New Year")
  elif speechstr=="李四":
   speaker.Speak("a beauty baby")
  elif speechstr=="王五":
   speaker.Speak("a little boy")
  elif speechstr=="赵六":
   speaker.Speak("a boy can coding")
  else:
   pass
 
if __name__ == '__main__':
 
 speaker.Speak("语音识别开启")
 wordsToAdd = ["张三",
     "你好",
     "国庆快乐",
     "新年快乐",
     "李四",
     "王五",
     "赵六",]
 speechReco = SpeechRecognition(wordsToAdd)
 while True:
  pythoncom.PumpWaitingMessages()
