本篇文章给大家分享的是有关Python中怎么实现一个语音识别框架，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
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:
