The correct spelling of the phrase "up minute" is actually "up-to-the-minute". The IPA phonetic transcription for this phrase is ʌp tu ðə ˈmɪnɪt. The "up" sound is represented by the symbol /ʌ/, while "to" is /tu/. The dash between "up" and "to" indicates that they are separate words, but should be pronounced together. "The" is represented by /ðə/, and "minute" is /ˈmɪnɪt/. So, when pronounced correctly, the phrase means "the most recent or current information".
