The word "Towned" is not a commonly used term, but it is spelled as /taʊnd/. This phonetic transcription indicates that the first syllable is pronounced with the vowel sound "ow" as in "cow", and the second syllable has the vowel sound "oo" as in "moon". The "n" is pronounced with a nasal sound, and the final "ed" is pronounced with the "d" sound only if the preceding vowel is unvoiced, which is the case here. Therefore, "Towned" is pronounced as "towned" and not "town-ed".
