@Cristian Camilo Bonilla Tellez Yes, you can synthesize the text to an audio file using the AudioConfig input with your speechSynthesizer class. Here is a sample to obtain the output as a .wav file.

    """performs speech synthesis to a wave file"""
    # 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 file as audio output.
    # Replace with your own audio file name.
    file_name = "outputaudio.wav"
    file_config = speechsdk.audio.AudioOutputConfig(filename=file_name)
    speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=file_config)

    # Receives a text from console input and synthesizes it to wave file.
    while True:
        print("Enter some text that you want to synthesize, Ctrl-Z to exit")
        try:
            text = input()
        except EOFError:
            break
        result = speech_synthesizer.speak_text_async(text).get()
        # Check result
        if result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
            print("Speech synthesized for text [{}], and the audio was saved to [{}]".format(text, file_name))
        elif result.reason == speechsdk.ResultReason.Canceled:
            cancellation_details = result.cancellation_details
            print("Speech synthesis canceled: {}".format(cancellation_details.reason))
            if cancellation_details.reason == speechsdk.CancellationReason.Error:
                print("Error details: {}".format(cancellation_details.error_details))

You can check the complete sample of the snippet from the speech SDK github repo.along with other possible scenarios.

To set a particular voice you need to set the same on speech config based on the available voices in your region. After setting the same you can use the same audio config to synthesize to file.

    voice = "Microsoft Server Speech Text to Speech Voice (en-US, JennyNeural)"
    speech_config.speech_synthesis_voice_name = voice
