Interestingly I feel like humans have this as well, sometimes.
Sometimes if someone is working though a complex thought and they're not really sure where they're going, they'll pause while thinking of the word they want to use, and might sound like
"the discussion is an... an... epistemological one"
Obviously they may have been conscious that the next word was going to start with "epi..." and they are just trying to remember the word, but I think sometimes they really don't consciously know what they're going to say, only unconsciously.
It reminds me of a recent New Yorker article about how people think, where the author realized they often have no idea what they're about to say before they open their mouths. [1]
