The spelling of the word "Chayse" may seem unusual, but it follows the rules of English pronunciation. The "ch" has the sound of "tʃ," as in "chair," while the "ay" has the long "a" sound, as in "hate." Finally, the "se" at the end creates the "s" sound, as in "peace." Therefore, the correct IPA transcription for "Chayse" is /tʃeɪs/, pronounced as "chay-s." Although it may take some getting used to, this spelling accurately reflects its pronunciation.
