Vowels
- All vowels are articulated with an unobstructed vocal tract
- Source of sound is the resonance created by the shape of the vocal tract
- Vowels are always voiced
\n
- vowels are articulated in the ‘vowel space’ * tongue position * high v low * front v back * lip position * unrounded v rounded
- round lips lengthen the oral track and dampen certain frequencies
- back vowels always rounded
- BOR labels for vowels: Backness, Openness, Rounding
- monophthongs: tongue is unmoving during articulation [i, æ, a, u, ɚ]
- diphthongs: tongue transitions from one vowel quality to another during articulation * ei: way, play, say, day * ai: why, ply, sigh, die * au: wow, pow, ow * oi: boy, joy
- vowels and nasals: the early opening of the velum will cause nasalization on the vowel * use tilde to represent nasalization
- r can be a consonant or a vowel * [ɹ]: consonant. alveolar approximant. (car, red) * [ɚ]: vowel. ‘schwar.’ (bird, girl)
