azure speech to text rest api python Connection aborted. OSError 10054, WSAECONNRESET

Question

I am trying to test azure speech to text the rest API. First of all I used POSTMAN client and it worked fine. Now I am trying the same thing using python but getting an error. I am following instructions given as per the https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-speech-to-text#

This is the code

file = open(test.wav','rb')
data = file.read()
import requests

url = "https://centralindia.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US"

payload = data
headers = {
  'Ocp-Apim-Subscription-Key': {key},
  'Connection': 'keep-alive',
  'Content-Type': 'audio/wav; codecs=audio/pcm; samplerate=16000',
  'Accept': 'application/json',
  'Transfer-Encoding': 'chunked',
      'Expect' : '100-continue'

}

response = requests.request("POST", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

Below is the error

Answer 1

Ok i am not sure if this is correct solution. But i can tell what resolved my problem

First of all tried the code given in the answer by Stanley Gong. It didnt give OSError 10054 but i got error as

b'{"error":{"code":"404","message": "Resource not found"}}'
404

So i was like oh something is working but then i compared my code with that of Stanley and thought what is causing the error?what is the difference

Then i commented out

 #'Transfer-Encoding': 'chunked',

in header

My working code (this time I am using request module)

file = open(r'test.wav','rb')
data = file.read()

import requests

url = "https://centralindia.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US"

payload = data
headers = {
  'Ocp-Apim-Subscription-Key': {key},
  'Connection': 'keep-alive',
  'Content-Type': 'audio/wav; codecs=audio/pcm; samplerate=16000',
  'Accept': 'application/json',
  #'Transfer-Encoding': 'chunked',
  'Expect' : '100-continue'

}

response = requests.request("POST", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

Thanks to Stanley and joshvito for responding
