Microsoft has collaborated with Project Gutenberg to create 5000 free audiobooks using AI technology. This project utilizes machine learning and natural voice synthesis to automatically convert eBooks into high-quality speech. The audiobooks cover a wide range of classic literature, drama, biographies, and more, and are freely available in an open-source manner. This project enriches the content of audiobooks and provides convenience for visually impaired individuals. This collaboration will greatly expand the number of free audiobooks offered by Project Gutenberg.
