Using the corresponding formant frequency values (measured in Hz), plot the following vowels on the graph below: Vowel: F1: F2: /i/ 270 2300 /I/ 400 2000 // 530 1850 // 660 1700 /a/ 730 1090 /u/ 300 870 F1 (Hertz) 200 300 400 500 600 700 800 900 2600 2400 2200 2000 1800 1600 1400 1200 1000 800 F2 (Hertz) 2. For vowels, we generally have only two resonating cavities instead of three. F1 is the resonant frequency associated with the __________________ cavity and F2 is the resonant frequency associated with the __________________ cavity. 3. Connect the dots on your graph...what did you create? ________________________ 4. RMS stands for ___________________ .Which measures the _______ of a complex wave. Source Filter Theory 1) When making a vowel, the source of our sound is the ________ 2) When making a vowel, the filters of out sound are ______,________, and ________
