The spelling of the word "Smilet" can be explained using the International Phonetic Alphabet (IPA). The first sound is /sm/, which is a consonant blend of the sounds /s/ and /m/. The second sound is /aɪ/ which represents the diphthong sound of "ai". The final sound is /lɛt/, which represents the sounds /l/ and /ɛt/. This could be pronounced as "sm-eye-let" or "smi-let". While not a commonly used word, it could denote a smile that is both small and quaint.
