I have this thing that I do where I get a book narration from Audible and the same book in ebook format for my Kindle, then I playback the narration at two or three times speed while I read along with the ebook in my browser window. So basically I listen to the book and read it at the same time at high speed. And what I wanted was a term I could use to describe this activity, which is something I have been doing for quite a while now. So, naturally, I asked ChatGPT and of all the suggestions it came up with I liked “DualStream” the most. Thus, hence forth, I will refer to this activity as dualstreaming.
