Adding Phrase using Phrase_List_grammar with Ms AZure SDK

Question

Hi
I tried with following codes to add a list of Medicines with Phrase List Grammar. My codes are producing the same inaccuracy. I hope they are not working.

CODE SAMPLE

*

import azure.cognitiveservices.speech as speechsdk
> import time

> service_region = 'MyRegion'

> speech_key='MyServiceKey'

> filename = 'Filepath/filename.wav'

> out_txtfile = 'Filepath//Filename.txt'

> **def speech_recognize_continuous_from_file():

>     """performs continuous speech recognition with input from an audio file"""

>     # <SpeechContinuousRecognitionWithFile>

>     speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)

>     audio_config = speechsdk.audio.AudioConfig(filename=filename)

>     speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

>     done = False

>     def stop_cb(evt):

>         """callback that stops continuous recognition upon receiving an event `evt`"""

>         print('CLOSING on {}'.format(evt))

>         speech_recognizer.stop_continuous_recognition()

>         nonlocal done

>         done = True

>     all_results = []

>     

>     #####  The following Lines I have addded to pass a PhraseList

>     

>     reco = speechsdk.SpeechRecognizer(speech_config=speech_config)

>     speechsdk.PhraseListGrammar.from_recognizer(recognizer: azure.cognitiveservices.speech.Recognizer)

>     phrase_list_grammar = speechsdk.PhraseListGrammar.from_recognizer(reco)

The above Code Block is not helping me to add the phrase list. I am not observing any increased accuracy of the output text.

I appreciate if anybody can modify the portion of code I need to correct.

Thanks
