Document Summary
Vowel height is reflected in frequency of f1 (higher the vowel, lower the f1; lower the vowel, higher the f1) Seems farther back when round lips, distance to exit of mouth farthe f2 drops more, more round the more it drops. Vowel height and formants: higher the vowel, lower the frequency of f1. Backness and formants: farther back the vowel, lower the f2. Rounding and formants: rounding causes f2 to drop. Vowels have steady state: formants are flat. Onset and offset there is rounding of formants. 1) sound 2) sign 3) seen 4) soon. Problems with ipa inconsistency with what symbols get used (what represents what) According to ipa [ae] and [a] considered low front vowels lots of vowel symbols in mid region not talked about imposing discrete symbols for phonetic space that is continuous. Vowel inventories lots of variation in how many vowels languages have. English has at least 10, cross linguistically unusual languages usually have symmetrical vowels.
