Apart from the base word 'supervised' (excluded), no common word rhymes with the whole word /ˌʌnˈsuːpərvaɪzd/ because the stressed syllable is 'su'. 'Improvised' (/ˈɪmprəvaɪzd/) comes closest in ending: it also has an unstressed final /-vaɪzd/, but its stressed vowel differs. 'Advised', 'revised', and 'devised' share the spelling '-vised' but stress the final syllable, so they are not rhymes. 'Prized' shares only the final /-aɪzd/ segment.
