Implication of phonetic knowledge about larynx
Pulmonic sounds
Circle the ones you can pronunceLink
The ‘r’ family
• Alveolar tap /ɾ/• Alveolar approximant /ɹ/• Alveolar trill /r/
• Uvular trill /ʀ/
• Retroflex /ɻ/
Bernoulli’s Law
Velocity & Pressure - inversely proportional
• velocity ↑ ! perpendicular pressure ↓
• the faster a fluid (liquid or air) travels over a surface, the less time it has to push on that surface
e.g. shower curtain, HSR, and your vocal folds
larynx
glottis
epiglottis
arytenoid cartilages
States of the glottis (I)
voiced (nearly together) voiceless (apart)
States of the glottis (II)
CreakyBreathy voice (murmur)p. 143Sound demo‘ahead’
Voice Onset Time (VOT)
The moment at which the voicing starts relative to the release of a closure
stop
(A) raise tongue to block air
(B) release the air
ta a
(C) voicing starts
VOT = C - B

Aerodynamics Airstream mechanismsPulmonic Non-pulmonic
Glottic VelaricPulmonic
Glottalic - outward
Glottal closure
Velar closure
Glottis raisedAir in pharynx compressed
Egressive
Example: ejective [k’]
Glottalic - inward air
Example: implosive [ɓ]
Glottis loweredair continue to flow through
Vf vibration
labial closure
labial closure released
Velaric

IPA MAHJONG
10 Patterns Rules• Everyone gets 10 cards - e.g. (2 x, 1ŋ, 3 y, 2 ɯ, 2 ɾ)• Goal - 3+3+3+2 (11)
• (waiting state��) 3+3+3+1 or 3+3+2+2
• pick up a card from the deck
• inherit the card from the person to your left
• “peng�” the card from anyone
• After reaching the “waiting state”
• a peer committes a suicidal behavior - 100 penalty from the loser
• you draw the exact card from the deck yourself!!! Penalty from EVERYONE!
Important rule
•Always, Always read alout the
description of the IPA symbol on the card you discard
Tokens
• Everyone gets 300 NTD to gamble
• Earn 300 NTD more (total of 600 NTD) - you get a coupon to wave the lowest quiz score of this class
Groups
• Group 1- 5 stays in the room with Yuwen
• Group 6 and follow Bonnie and Hui-ting to the lobby (take all your belongs with you)
have two practice rounds to get familiarized with the rules!!
What do you need when your cards are like these?
