A patient with ankyloglossia (tongue-tie) has difficulty producing which type of sound?

  1. Linguoalveolar sounds such as T, D, N, and L (and the R sound)
  2. Bilabial sounds such as P and B
  3. Labiodental sounds such as F and V
  4. Vowel sounds only
Show answer and explanation

Correct answer: A. Linguoalveolar sounds such as T, D, N, and L (and the R sound)

Ankyloglossia restricts tongue-tip elevation needed for linguoalveolar sounds (T, D, N, L) and rolling of R, impairing those phonemes.Other options: Bilabial (P/B) and labiodental (F/V) sounds rely on the lips/teeth, not tongue-tip elevation; vowels are not primarily affected.Key exam takeaway: Tongue-tie impairs tongue-tip sounds: T, D, N, L (and R).
