Liquids

1. Lower amplitude than vowels
2. Generally higher amplitude than nasals
3. Vowel-like in formants
4. F3 lower than 2000 Hz (varies for speakers) (9r)
5. F2 close to F3 (9r)
6. -Rr high F3 combined with low F2 to form ``o'' shape (l)
7. Slower formant transitions than for stop+vowel
8. Fluidity between vowel and liquid
