you can’t recognize voices without an internal monologue? I see no reason that shouldn’t be a thing people would even consider. Voices are like identifying unique patterns. They’re incredibly easy, and we’re trained to do it from birth. Similar thing for songs, although in that case i think it’s more a sense of auditory “muscle memory” as the auditory experience illicits previously excited paths through the brain, leading to the same experience as last time, which allows you to define it independently.
