I am trying to send stream to azure speech to text using the below logic

def get_speechstream_text_async(self,stream):

    try:
        print('push shart')
        stream_format= speechsdk.audio.AudioStreamFormat()
        custom_stream= speechsdk.audio.PushAudioInputStream(stream_format)
        print('again end')
        custom_stream.write(stream)
        print('push end')

        audio_config = speechsdk.audio.AudioConfig(stream=custom_stream)
        speech_recognizer = speechsdk.SpeechRecognizer(speech_config=self.speech_config, audio_config=audio_config) 
when i am trying the feed the stream i am getting this error 
"error in method 'PushAudioInputStream_write', argument 2 of type '(TYPEMAP, SIZE)'"

Can someone please help on what is the issue here and how to pass to stream to get the speech to text
