Not even close. They are different, non-meaningful pronunciations (variants) of the same phoneme (basic sound unit) that occur in specific, predictable phonetic environments, like the aspirated 'p' in "pin" versus the unaspirated 'p' in "spin". Speakers of a language perceive these variations as the same sound, but they are distinct phonetic realizations that don't change a word's meaning, unlike phonemes which do.
