Everything Vocab and Phon. Proc. Mod 1 Exam 1 Flashcards
Phonetics
the study of the production and perception of speech sounds
Phoneme
Sound that makes up a word
Allophone
phonetic variations of a phoneme (sound is slightly different, but doesnt change the meaning of a phoneme. Ex. top and button)
Grapheme
smallest units of writing system. (NOT SOUNDS)
Allograph
different spellings for each sound
Consonant Digraph
2 letters that represent a single phoneme (sh, th, ch, ph)
Morpheme
smallest unit of language capable of carrying meaning (book=1 vs books=2)
Minimal Pairs
pairs of morphemes that only differ by one sound segment (hot, pot, cot, rot, lot)
Digraph
2 letters making one sound (ea = i)
Parts of a Syllable
vowel with one or more consonants -> onset, nucleus, coda
Articulation
process of moving structures of the vocal tract so that they join together in different positions
Place
places where the airstream is constricted by the articulators (where)
Manner
ways the airstream is modified by articulators (how)
Voicing
whether or not the vocal folds are vibrating when sound is produced
Review Anatomy of Sound Production
- velum: radiation of sound, moves up to close the nasal cavity for oral radiation and down to open nasal radiation, acts as point of contact for velar sounds like /k/ and /g/
- epiglottis: closes entrance to larynx and trachea during swallowing, sits at upright position at rest allowing air to pass
- vocal folds: muscles of the larynx bring the VF together at onset of phonation, the force of air from the lungs blows VFs apart causing vibration
- alveolar ridge: tip of the tongue hits AR to form consonant sounds
- articulators: move structures to VT so they can join together in different positions
- look at graph
Characteristics of Vowels
voiced
resonate in oral cavity
open vocal tract
nucleus of a syllable
Monophthong
pure vowel sounds with a stable articulation (beat, boot, bat)
Diphthong
gliding movement between two vowel qualities within the same syllable (boy, boat)
Review Vowel Quadrilateral
Review
Stops (Manner)
complete closure of vocal tract, air pressure builds behind closure
/p/ (as in “pat”)
/b/ (as in “bat”)
/t/ (as in “top”)
/d/ (as in “dog”)
/k/ (as in “cat”)
/g/ (as in “goat”)
Fricatives (Manner)
Articulators form narrow constriction and airflow is channeled
/f/ (as in “fan”)
/v/ (as in “van”)
/θ/ (as in “think”)
/ð/ (as in “this”)
/s/ (as in “sun”)
/z/ (as in “zoo”)
/ʃ/ (as in “ship”)
/ʒ/ (as in “measure”)
/h/ (as in “hat”)
Affricates (Manner)
combo of stop and fricative
/ʧ/ (as in “chat”)
/ʤ/ (as in “jam”)
Nasals (Manner)
pulses of air from vibrations of VFs must pass through nasal cavity
/m/ (as in “man”)
/n/ (as in “no”)
/ŋ/ (as in “sing”)
Glides (Manner)
semi-vowel partially constricted state to more open for vowels
/w/ (as in “wet”)
/j/ (as in “yes”)
Liquids (Manner)
vowel-like consonants, VT constricted slightly more than vowels
/l/ (as in “love”)
/r/ (as in “run”)
Stridents (Manner)
affricates and noisy fricatives
/f, v, s, z, sh, ch, dj (j)/
Obstruents (Manner)
constriction of VT to obstruct airstream
stops, fricatives, affricates
Sonorants (Manner)
vowel-like quality
nasals, glides, liquids
Bilabial (Place)
“two-lips” most anterior
/p, b, m, w/
Labio-dental (Place)
both lips and central incisors (2 upper and lower teeth besides midline)
/f, v/
Lingua-dental or interdental (Place)
Tongue touches the bottom edge of the upper central incisors or the backs of central incisors
/th/
Lingua-alveolar (Place)
Immediately behind the upper central incisors
/t, d, n, s, z/
Lingua-palatal (Place)
posterior to alveolar ridge
/sh, funny 3, ch, dj (j), r, and j/
Lingua-velar (Place)
back of the oral cavity, posterior to palatal area, and anterior to uvula
/k ,g, ng/
Glottal
opening behind vocal folds
/h, glottal stop/
Syllable Deletion (Syllable Structure Processes)
syllable of a polysyllabic (multiple vowel sounds) word is omitted
typically syllable deleted is unstressed
Reduplication (Syllable Structure Processes)
partial or total repetition of a syllable of a word
Diminutization (Part of Reduplication) (Syllable Structure Processes)
Adding /i/ at the end
Epenthesis (Syllable Structure Processes)
vowel is inserted between two consonants
typically a schwa
Final-Consonant Deletion (Syllable Structure Processes)
deletion of a singleton consonant in a word final position
postvocalic /r/ and /l/ are considered as vowels and not counted in final consonant deletion
Cluster Deletion (Syllable Structure Processes)
deletion of some or all of the consonants in a cluster
Cluster Substitution (Syllable Structure Processes)
one member of a cluster is replaces with another consonant
Coarticulation
one sound influences another
/b/ in bat is different then /b/ in bet because different vowel sounds follow
Linguistic Complexity
- isolation: child is asked to say a sound /s/, or a series of sounds /s, f, z/, which clinician scores or transcribes
- word: clinician asks child to say words that contain that /s/ sound
- sentence: read multitude of sentences, each of which is composed of several words that contain one or more /s/ sound
- continuous speech or conversation: clinical will transcribe entire speech sample
Response Complexity
- one sound: score one specific sound or cluster per word (in isolation)
- multiple sounds: clinician scores 2-4 target sounds per word
System Complexity
- 2-way scoring: “correct” or “incorrect”
- 5-way scoring: whether a sound is right or wrong, but also what type of error occurred
- phonetic transcription: describes what a child says rather than to score it relative to some arbitrary standard
SODA
- substitution: sound replaced with another
- distortion: articulation of sound is incorrect
- omission or deletion
- addition
Prosody Variations
- primary stress: highest stress, increased pitch, duration, and intensity over vowel
- contrastive: beginning of word has emphasis
- lengthening: prolonged sound
- falling terminal juncture: pitch falls down at the end of a sentence (WH ?’s)
- rising terminal juncture: pitch goes up at the end of a sentence
Allophonic Variations
- nasalized: velopharyngeal port opens creating resonance in the nasal cavity
- denaslized: VP is closed and /m, n, ng. are not nasalized
- dentalized consonant: tongue touching or in between the teeth
- lateralized consonant: airflow on the sides of the tongue
- derhotacized consonant: “r” word missing the “r-ness”
Sound Source Variation
- breathy voice: incomplete closure of VF
- glottalized: irregularity in laryngeal vibratory system
- whistled: under fricatives - sometimes like normal whistling
Other Variations
- synchronic tie: 2 sounds said as 1
- syllabic consonant: /m, n, l, ng, r/
Stopping (Substitution Process)
replacing fricatives, affricates, liquids, and glides with a stop
/p, b, t, d, k, g, glottal stop/
Phonological Processes (Substitution Process)
involve some form of segment substitution that occurs independently of phonetic context
not defined by simple substitution of one segment for another
Stridency Deletion (Substitution Process)
stident consonant omitted or replaced with a nonstrident consonant
/s, z, sh, su, ch, j/ replaced
Fronting (Substitution Process)
replacing back sounds /k, g, ng, ch, j, sh, and su/ with front sounds
Depalatization (Substitution Process)
palatal sound replaced with a nonpalatal sound
/sh, su, ch, j, r, and y/ replaced
