The spelling of the word "shupe" can be explained using the IPA phonetic transcription. The first sound, represented by the /ʃ/ symbol, is a voiceless postalveolar fricative. This sound is followed by the vowel sound /u/, which is pronounced as a high back rounded vowel. Finally, the ending sound is a voiceless bilabial plosive, represented by the symbol /p/. So the spelling of the word "shupe" corresponds to the sounds /ʃuːp/, meaning it's pronounced like "shoo-p".
