这里大家需要改成自己的ID和KEY


APP_ID = \'11****843\'
API_KEY = \'3Mnv***8**88******GbXa\'

SECRET_KEY = \'147***8*88****1227684\'
aipSpeech = AipSpeech(APP_ID, API_KEY, SECRET_KEY)




def getText(url):
  text = requests.post(url).json()
  return text[\'text\']



##
##key = \'6ddc57c5761a4c62a30ea840e5ae163f\'
#api = \'http://www.tuling123.com/openapi/api?key=\' + key +\'&info =\'
key = \'8b005db5f57556fb96dfd98fbccfab84\' 
api = \'http://www.tuling123.com/openapi/api?key=\' + key + \'&info=\'

while True:
  
##  info = input(\"我说\\n\")

 
##  chunk=2014

  my_record()
  print(\"录音完成\")
  

  
  def get_file_content(filePath):

  print(a)
  b = str(a[\'result\'])
  info = b

  
  url = api + info
  #print(url)

  text_01 = getText(url)
  print(\"机器人回\\n\",text_01)

  now = datetime.now().strftime(\"%Y-%m-%d_%H_%M_%S\")
  filename_01 = now + \".mp3\"

  result = aipSpeech.synthesis(  text_01,\'zh\',1,{\'vol\': 5,\'per\' : 2} )
