当我运行我的代码时，wit.ai 尝试识别“myspeech.wav”的英文单词，但这是波斯语，我应该如何更改我的代码？
def RecognizeSpeech(AUDIO_FILENAME):
audio = open('myspeech.wav','r')
headers = {'authorization': 'Bearer ' + wit_access_token,
'Content-Type': 'audio/wav'}
resp = requests.post(API_ENDPOINT, headers = headers,
data = audio)
data = json.loads(resp.content)
text = data['_text']
return text
