The spelling of the word "p i s" may seem confusing, but it is actually phonetically consistent. The IPA transcription of this word is /pɪs/. The first letter "p" represents the voiceless bilabial plosive sound, followed by the short "i" vowel sound represented by the letter "i", and finally the voiceless alveolar fricative sound represented by the letter "s". When pronounced together, the word "p i s" sounds like "pis", with a short, sharp burst of air and a hissing sound.
