    # Set up headers with your secret key
    headers = {
        "Authorization": "Bearer YOUR_SECRET_API_KEY",
        "Accept": "application/json"
    }
    
    # Prepare the audio file and parameters
    data = {
        "source_lang": "vi",
        "target_lang": "en"
    }
    
    files = {
        "file": open(file_path, "rb")
    }
    
    # Execute the POST request to start
    response = requests.post(url, headers=headers, data=data, files=files)
    
    # Return the processed JSON data result
    return response.json()
Handle the response carefully in your application code.
