The phrase "am on back of" might seem simple, but it can be confusing to spell. In IPA phonetic transcription, it would be written as /æm ɒn bæk əv/. The "am" is pronounced with the vowel sound in "hat," while the "o" in "on" has a longer, rounded sound like the "o" in "sore." The "a" in "back" is pronounced with the same short "a" as in "am," but the "ck" is pronounced like "k." Finally, the "of" is pronounced with a short "o" sound like in "hot" and a subtle "v" sound at the end.
