”speck” and ”spec” are given an identical pronunciation in all dictionaries i looked at, with wiktionary listing them as homophones. it seems unlikely you’re pronouncing ”Spec” differently from ”spec”, and i don’t know how you’d do that it really.
sorry for being harsh but i think it’s very likely you’re gaslighting yourself into thinking they’re pronounced differently, which is not the case for the vast majority. perhaps you’re really pronouncing them in a slightly different way, but i doubt that difference is audible—and in any case, it isn’t clear in writing.
to clarify, this confused me as well when reading it and took me out a bit at the end. i wondered for a bit whether it was a stylistic choice— portraying his thoughts and thus spelling the same sounds two distinct ways based on them. i also wondered for a bit whether you were trying to accentuate how immersed he was, as he was thinking aloud about two identical-sounding names. yeah i was way overthinking it lol
