The spelling of the word "shot mouth" may seem a little peculiar, but it can be explained through IPA phonetic transcription. The first syllable is pronounced as "sh-aw-t", with the "a" sound being a mid-back rounded vowel. The second syllable is pronounced as "m-aw-th", with the same mid-back rounded vowel. The spelling of "shot" is phonetically accurate to the pronunciation, but "mouth" is spelled without the additional "u" commonly seen in British English.
