| Question | Answer |
|---|---|
| obstruants vs sonorants | obstruent consonants have great constriction of the VT -sonorants are produced with continuous airflow -some consonants, and all vowels are sonorant |
| 3 types of obstruants | stops, fricatives, and affricates |
| what is a stop sound | -There is complete, brief closure of the vocal tract. -during closure, air pressure builds (stop gap) -sound releases quickly (stop burst) |
| how many types of stop sounds are there | 5: -bilabial stop -alveolar stop -alveolar tap -velar stop -glottal stop |
| bilabial stops | /b/ and /p/ -constriction at lips |
| alveolar stops | /t/ and /d/ -constriction at tongue and AR |
| alveolar tap stop | very fast, stop-like sound -intervocalic position |
| velar stops | /k/ and /g/ -constriction at velum and back of tongue |
| glottal stop | "batman" -constriction at glottis -always voiceless |
| what is a fricative sound | narrow constriction, still allowing airflow to continue through the vocal tract, but the opening is so constricted that the airflow becomes TURBULENT. -'noisy' |
| labiodentals | fricative sounds /f/ and /v/ -partial constriction at upper incisors and lower lip |
| dentals/interdentals | fricative sounds /θ/ and /ð/ (theta and ethe) -partial constriction at tip of tongue and behind or protruding incisors. |
| alveolars | fricative sounds /s/ and /z/ -partial constriction of tip of tongue to AR |
| palatals | sibilant, fricative consonants /ʒ/ and /ʃ / -airflow is directed over the tongue to create turbulence as it strikes alveolar ridge and/or teeth |
| glottal fricative | /h/ -open VT and narrowed glottis |
| /d/ and /n/ | |
| /b/ and /m/ |
