I use TTS to generate pseudo audio books and listen to light novels while working out/driving.
Though one weird quirck of doing this is you don’t get to see the pictures as you read For j-novel books I unzip the book and extract the pictures.
Some times I view all the pictures before listening to the book other times I view them after finishing the book.
