Exercise3:
Please query the vowels [a:],[i:],[u:],[e:], and [o:] and extract their formants. 
Try to find the outliers, or at least those parts at which
F1 or F2 are 0. Remember that you can find errors in T1 OR T2 by using the OR operator " | ".

Use the parameter "seglist =" in serve() in order to correct the formants. Remember: Press keys 1 or 2 (= selection of Formant 1 or 2); Pressing the key "Shift" plus movement of the mouse moves the selected formant.
