CMD 276 Lecture Notes - Lecture 3: Baryon Acoustic Oscillations, Vocal Tract, Formant
Document Summary
Inverse relationship between vowel height and formant frequency: higher the vowel, lower f1. Inverse relationship between oral cavity length and formant frequency: increased oral cavity length, lower f2. The length rule : the longer the length of the tract, the lower all the average formants will be. Refers to the narrowness of points along the oral-pharyngeal the tract when it is in certain shapes. Guidelines: formants are viewed as high or low when compared to the formants for the neutral vowel schwa. The first, second, and third formants for unstressed schwa spoken by an adult male talker of average size are 500, 1500, and 2500 hz. Lip constriction: lips are rounded for /u/ and /o/ but less for /o/ than /u/ Therefore, /u/ has a greater amount of lip constriction: vowels /c/ and /a/ have progressively less lip constriction. Portray speech events visual representation of formants. Steady state formants are a result of clear tongue positions.
