The primary reason listeners overestimate Grande's foreign language skills comes down to her vocal mechanics. Grande is widely recognized by producers and peers as an extraordinary sonic mimic, capable of replicating the exact timber, vibrato, and articulation of artists like Celine Dion, Britney Spears, and Christina Aguilera.
That exact auditory skill applies to how she processes speech. While an average native English speaker struggles with dental consonants and pure vowels, often adding diphthongs to Spanish sounds, Grande mimics native acoustic placements instantly. She lands directly on the pure vowel sounds (/a/, /e/, /i/, /o/, /u/) without sliding between notes.
Her natural pronunciation and accent sound authentic because her auditory processing is geared toward replication. However, phonetic replication is not structural syntax. Her brain stores the acoustic signature of the phrase, not the underlying conjugation matrix.
Interestingly, Spanish is not the language she has studied with the most academic rigor. Between 2015 and 2019, Grande directed her focus toward Japanese, hiring private tutors, learning Hiragana and Katakana scripts, and frequently showcasing written practice online. Even with that sustained effort, achieving conversational dexterity proved challenging, ultimately underscoring how difficult true secondary language acquisition remains for touring superstars.
