P&P 6-10 Flashcards
Types of airstream mechanism
- pulmonic (egressive, ingressive)
- glottalic (ejectives, implosives)
- velaric (clicks - only ingressive)
Glottal airstream
can be egressive (ejective) or ingressive (implosive) - movement of glottis up or down changes pressure in oral cavity - pushes air out or causes air to be sucked in.
Ejective
vocal folds together and moving upward
Implosive
closed vocal folds moving down, usually nearly closed moving down with regular vibrations or creaky voice (can have voiceless diacritic)
Steps of glottal egressive velar stop k’ e.g. occasionally when saying words like “bike”
- velar closure and glottis closure happen same time
- closed glottis is raised
- body of air in pharynx is compressed
- back of tongue is lowered, releasing compressed air,
- glottal closure is released
Steps of bilabial implosive e.g. in Sindhi
- closure of lips
- downward movement of vibrating glottis (continues to flow air - leaky)
- little change in pressure of oral tract
- lips come apart
Steps for dental click
- velar closure and front closure
- body of tongue moves down while other closures maintained, decreasing pressure in front
- tongue tip lowered so air rushes in
- velar closure released
4 states of the glottis
- voiced
- voicelessness
- murmur
- creaky voice
- whisper
Voiceless phonation
apart not vibrating - wide opening of glottis
Voice (modal)
normal vocal vibration along most of the length of the glottis
Murmur (breathy voice)
Normal cord vibration accompanied by continuous turbulent airflow - vibrating while never fully together
Creaky
Vocal folds held tightly together (posterior) but vibrating anteriorly - low frequency of vibration
Whisper
greater constriction than voicelessness - adapting the vocal cords while maintaining the opening of the glottis
Falsetto
vocal cords are stretch longitudinally so they become thin in cross-section
Aspiration (glottis action)
vocal folds apart during release of an articulation
Types of stops in Hindi
- Voiceless unaspirated [p]
- voiceless aspirated [pʰ]
- voiced [b]
- breathy voiced [bʱ]
Breathy voiced
occasionally called aspirated - really means there is a period of breathy voicing or murmur before the regular voicing starts
Other types of sounds not in English
- bilabial fricatives
- linguo-labials (tongue touches upper lip)
- labiodental stops
- labiodental nasal (except allophonic)
- dental stop (except allophonic)
- retroflex stops
- alveolo palatal
- palatal voiceless e.g. ich bin nicht or nasals e.g. se/ɲ/or (spanish)
- velar fricatives [x]
- uvular e.g. French voiced uvular fricative
- pharyngeal fricatives
- labial velar stops/nasals
Labiodental nasals in English
[ɱ] may occur where /m/ before /f/ – as in emphasis or symphony
palato-alveolar
target on upper surface of the mouth is about the same as retroflex (margin of alveolar and palate) but tongue is domed, not hollowed (sh)
apical vs laminal
tip of the tongue (am)
blade (lam)
alveolo-palatals
Polish and Chinese fricatives similar to sh, but with raising of the front of the tongue
sibilant sounds
fricatives s, z, sh, sz - more acoustic energy (loudness) than others
trills
trill - [r]
tap vs flap
both caused by single contraction so one articulator thrown against another
tap - tip of tongue contacts dental/alveolar
flap - tip of tongue retroflex then strikes roof in post-alveolar region
sufficient perceptual separation
force acting on a language so that sounds are kept acoustically distinct to make it easier for listeners to distinguish
features of vowel quality
- height (F1 freq)
- backness (F2 and F1)
- rhotacisation
- rounding
- ATR - width of pharynx
- nasalisation
secondary articulation
gesture with a lesser degree of closure occurring at roughly the same time as the primary gesture e.g. palatalisation, velarisation, pharyngealisation, labialisation
palatalisation vs velarisation
raising of front of tongue or back e.g. /k/ey or dark l
pharyngealisation
retracting the root of the tongue e.g. in dark l
labialisation
rounding of the lips in e.g. coo
syllabification
the process of breaking words into syllables
σ (sigma sign)
Used to show syllable
