Document Summary

The resonating frequencies will be odd number multiples of the lowest resonating frequency. More likely that this speech came from a male speaker, because their vocal tracts are usually longer. The resonating frequencies in each of these cavities is different. Our single tube model for [ ] assumes an unconstricted vocal tract. If we assume that the highest point of the tongue forms a constriction; then the oral cavity can be divided into two tubes. A back tube (volume of air behind the constriction) A front tube (volume of air in front of the constriction) Both tubes can be assumed to be closed at one end and open at the other. Vowel formants from a two-tube model will be. The lowest resonant frequency (f1 will be the lowest resonant frequency of either of these two, f2 will be the second lowest resonant frequency from either of these two, and so on)
