The spelling of the word "LAET" can be explained using the International Phonetic Alphabet (IPA). The first sound is represented by the symbol /l/, which is a voiced alveolar lateral approximant. The second sound is represented by the symbol /eɪ/, which is a diphthong consisting of a long vowel sound /e/ followed by a glide /ɪ/. The final sound is represented by the symbol /t/, which is an unvoiced dental plosive. Therefore, the spelling of "LAET" represents the sounds /l/ + /eɪ/ + /t/.
