Notice that when you round your lips, your lips protrude a little bit forward. Assume that this lip rounding adds 1 cm to the length of the vocal tract. Do you expect that a vowel produced with rounded lips will have higher or lower resonant frequencies than the same vowel produced with unrounded lips? correct answers lower
Explain why the resonant frequencies will be higher or lower. correct answers The resonant frequencies will be lower because resonant frequencies are determined by vocal tract length. Increasing the length of the vocal tract by protruding the lips will cause the resonant frequencies to be lower. When you use the formula, (2n-1)c/4L, and divide the speed of
