The spelling of the word "hevy" is incorrect. The correct spelling is "heavy" /ˈhɛvi/. The IPA phonetic transcription for "heavy" is /ˈhɛvi/, which includes the sounds /h/, /ɛ/, /v/, and /i/. The letter "h" produces the /h/ sound like the hissing sound of air. The letter "e" produces the short /ɛ/ sound like in "red." The letter "v" produces the /v/ sound like in "vote." The letter "y" produces the /i/ sound like in "my."
