What's different

After s, the t has no puff of air, so the vowel starts at once and you hear all of it. Star opens wide: the jaw drops for a clear "ah". Stir barely opens: it's the muffled "er" of bird, with the jaw only slightly open.

American voices give a second clue. Stir is r-colored from its very first moment, so the whole vowel sounds like one long r. Star starts on a plain "ah" and only curls into r at the end. British and Australian voices drop the r, so compare how far the mouth opens.
