The spelling of the word "devie" is quite straightforward when using the International Phonetic Alphabet (IPA). The first syllable, "dev," uses the IPA symbol for the voiced dental fricative /ð/, which is pronounced like the "th" in "this." The second syllable, "-ie," comprises the long vowel /i:/ as in "tea" and the consonant sound /i/ as in "kit." Therefore, the correct IPA transcription for "devie" is /ˈdeð.i:/.
