  1. Distinguishing /r/ from /l/
  2. Three formants are required for perception of /r/ & /l/
    • F3 distinguishes /r/ from /l/ - F3 is the lowest for /r/ being between 1200-1800 Hz, while F3 for /l/ is between 2400-3000 Hz
    • In most vowel contexts, F3 for /l/ does not vary in frequency
  3. Distinguishing /w/ from /j/
  4. O’Connor et al – synthesized perceptually acceptable /w/’s and /j/’s with only 2 Formants
    • F1 for both sounds is similar – very low
    • F2 distinguished these sounds as F2 for /j/ is much higher (2300 Hz) than for /w/ (900 Hz).
