Personally I don’t really differentiate so I will say I “read” a book even if I technically listened to it, or I will say things like “I’ve read X amount of books so far towards my yearly reading goal” even if a portion of those books were audiobooks.
I have noticed though that a lot of people tend to specify when they’ve listened to an audiobook. I wonder if this is because of a slight linguistic discomfort using the verb “read” even when you didn’t look at words on a page (I also felt this discomfort for a time as I started getting into audiobooks but have mostly gotten over it), or is it because they consider the experience of reading an audiobook so fundamentally different that it doesn’t even count as reading?
Part of the difference is, each version of a book is formatted separately, and one of the things I’ll let other readers know about is any issues I had with my chosen version, Kindle editions. Many reviewers I follow on Goodreads will do similar, that’s where I learned it was a good idea. I’ve really appreciated this if I read a book, particularly when scene breaks are poorly distinguished, or a break is missing.
AUDIOBOOKS! Warning: soapbox:
All versions of written stories involve consuming those stories, all versions are valid. Let’s just stop being ableist about it, please. If you can’t see, you read via audiobooks, okay? Okay. Plus, it doesn’t have to be an ability problem; if you spend a lot of time traveling, same deal! When someone reads a story aloud, it’s from the written version.
end: soapbox
Oh, a friend of mine calls reading audiobooks “ear-reading.” Feel free to steal if that fits your experience.
