python语音识别的转换方法

from win32com.client import Dispatch
speaker = Dispatch('SAPI.SpVoice')    #创建Dispatch对象
speaker.Speak('大家好')        #调用Speak方法
del speaker     #释放

#读取文本内容

#将语音转换成文本 使用PocketSphinx

    audio = r.record(source)

    print('文本内容：',r.recognize_sphinx(audio,language='zh-CN'))  #指定中文
except Exception as e:
    print(e)
