Improved error handling and added audio transcription

The code changes include improved error handling in the image generation script. Now, instead of directly printing the URL, it checks if there's an error in the response and prints that instead. If no error is found, it proceeds to print the URL as before.

In addition, new functionality for audio transcription and speech creation has been introduced. This update is reflected in the README file along with other minor formatting adjustments for better readability.
