The correct spelling of the phrase "wast on par" is actually "wasn't on par". In IPA phonetic transcription, this would be /wɒznt ɒn pɑː/. The first part of the phrase, "wasn't", is a contraction of "was not" and is pronounced with the short vowel sound of the letter 'o'. The second part, "on par", has a long 'a' sound and is pronounced with the British English accent, where the 'r' is not pronounced as strongly as in American English.
