The word "ALTMTMRE" may seem like a jumbled mess of letters at first glance, but it is actually a phonetic spelling of the phrase "all that matter". The IPA phonetic transcription breaks it down as /ɔːl ðæt ˈmætə/, with the first syllable "all" pronounced with an open-o sound, and the second syllable "that" pronounced with a voiced th sound. The final syllable "-ter" in "matter" is reduced and almost silent. So, "ALTMTMRE" is just a quirky way of representing the sounds in "all that matter"!
