Why is the Argentine accent so distinct from other Spanish-speaking countries?

The Argentine accent, particularly the Rioplatense dialect, is distinct due to historical influences and unique phonetic characteristics. Massive Italian immigration in the late 19th and early 20th centuries significantly impacted the accent, infusing intonation patterns similar to Italian. Additionally, the use of voseo (using “vos” instead of “tú” for “you”) differentiates Argentine Spanish from other varieties. The pronunciation of the “ll” and “y” sounds as a “sh” or “zh,” known as “yeísmo,” further distinguishes it. These linguistic features create the unique and recognizable Argentine accent among Spanish-speaking regions.
