Alesso is a proper noun used primarily as a surname or given name in Italian and Spanish-speaking contexts. It is pronounced with two syllables, emphasizing the first: /aˈlɛs.so/ in Italian, often anglicized in English as /əˈlɛsoʊ/ depending on speaker. The name carries a melodic cadence and tends to retain a soft, open initial vowel sound followed by a clear syllabic break before the final vowel.
