Is formant F always a multiple of F0?

One question about formant frequency:
Is always a formant frequency F(i), i = 1,2.. a multiple of fundamental
frequency(pitch) F(0)?

if you are referring to formants in the human voice, the answer is no. the formants are determined by the shapes of the mouth, throat, and nasal cavity. the fundamental frequency is determined by muscular tension on the vocal "cords". when you sing the same note, but change the sung word from "leee" to "laaa", the pitch stays the same, but the formants change. r b-j
