(platform: ElevensLab) The primary reason for this choice is to ensure a cleaner audio quality. As English is not my first language, it can be difficult to keep this kind of content clear and concise. I believe that the generated voice enhances the educational quality of these tutorials. With that said, this is not a definitive choice.
