@Neunit AI Welcome to Microsoft Q&A Forum, Thank you for posting your query here! Could you please update your azure.cognitiveservices.speech python package to the most recent version and test again ?
.
I used the below sample and I couldn't hear any noise / sound at the end. Could you please try to use the below sample code and check if that helps ?

import azure.cognitiveservices.speech as speechsdk

# Replace with your own subscription key and region identifier from Azure.
speech_key = "027cd6XXXXXXXXXXXXXde65e"
service_region = "westeurope"

# Creates an instance of a speech config with specified subscription key and service region.
speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)

# Creates a speech synthesizer using the default speaker as audio output.
speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config)

# Receives a text from console input and synthesizes it to speaker output.
text = "Hello world, Microsoft Cognitive Services Speech service is awesome!"

# Encapsulate the text within speak and voice tags to indicate the language, gender and the text to be spoken.
ssml_string = f"""
<speak version='1.0' xmlns='http://www.w3.org/2001/10/synthesis' xml:lang='en-US'>
  <voice name='en-US-JennyNeural'>
    {text}
  </voice>
</speak>
"""

# Performs the text-to-speech process
result = speech_synthesizer.speak_ssml_async(ssml_string).get()

# Checks result.
if result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
    print("Speech synthesized to speaker for text [{}]".format(text))
elif result.reason == speechsdk.ResultReason.Canceled:
    cancellation_details = speechsdk.SpeechSynthesisCancellationDetails.from_result(result)
    print("Speech synthesis canceled: {}".format(cancellation_details.reason))
    if cancellation_details.reason == speechsdk.CancellationReason.Error:
        if cancellation_details.error_details:
            print("Error details: {}".format(cancellation_details.error_details))
    print("Did you update the subscription info?")

Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
