When you voice the vowel sound in "hat," you narrow the opening where your throat opens into the cavity of your mouth so that your vocal tract appears as two connected tubes. The first is in your throat, closed at the vocal cords and open at the back of the mouth. The second is the mouth itself, open at the lips and closed at the back of the mouth-a different condition than for the throat because of the relatively larger size of the cavity. The corresponding formant frequencies are 650 Hz (for the throat) and 1400 Hz (for the mouth). Assume a sound speed of 350 m/s. What is the length of the throat? Express your answer with the appropriate units. Muest Answer V PartB What is the length of the mouth? Express your answer with the appropriate units. L = Value Units Muest Answer I Review
