Get Speech Studio files from Azure Cognitive Text to Speech API (or SDK)

Question

There is any way to get the files generated in the Speech Studio using the REST API or SDK?

I'm working on a project where I want to create several audios from text, I like the Speech Studio tool, so we are thinking on integrate it to the workflow, creating audios in Speech Studio and after request them in the app.

There is no API to export the audio from Azure Speech Studio Audio Creation Center. But you can generate your audio directly by API/ SDK and export it.

API example -

 curl --location --request POST "https://${SPEECH_REGION}.tts.speech.microsoft.com/cognitiveservices/v1" \
--header "Ocp-Apim-Subscription-Key: ${SPEECH_KEY}" \
--header 'Content-Type: application/ssml+xml' \
--header 'X-Microsoft-OutputFormat: audio-16khz-128kbitrate-mono-mp3' \
--header 'User-Agent: curl' \
--data-raw '<speak version='\''1.0'\'' xml:lang='\''en-US'\''>
    <voice xml:lang='\''en-US'\'' xml:gender='\''Female'\'' name='\''en-US-JennyNeural'\''>
        my voice is my passport verify me
    </voice>
</speak>' > output.mp3

Python SDK example

import os
import azure.cognitiveservices.speech as speechsdk

# This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"
speech_config = speechsdk.SpeechConfig(subscription=os.environ.get('SPEECH_KEY'), region=os.environ.get('SPEECH_REGION'))
audio_config = speechsdk.audio.AudioOutputConfig(use_default_speaker=True)

# The language of the voice that speaks.
speech_config.speech_synthesis_voice_name='en-US-JennyNeural'

speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)

# Get text from the console and synthesize to the default speaker.
print("Enter some text that you want to speak >")
text = input()

speech_synthesis_result = speech_synthesizer.speak_text_async(text).get()

if speech_synthesis_result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
    print("Speech synthesized for text [{}]".format(text))
elif speech_synthesis_result.reason == speechsdk.ResultReason.Canceled:
    cancellation_details = speech_synthesis_result.cancellation_details
    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 set the speech resource key and region values?")

In studio the only way to export the audio is the "Export" button
