MIDTERM- CH 2 Flashcards
(43 cards)
Respiratory System:
Includes lungs, airway, rib cage, diaphragm.
Provides the air supply for sound generation.
Larynx:
Composed of cartilages and muscles.
Generates voiced sounds through vocal fold vibration; regulates airflow for voiceless sounds.
Tongue:
Principal articulator, capable of various shapes/positions.
Divided into five parts: tip, blade, back, root, body
Velopharynx:
Includes the soft palate (velum) and velopharyngeal port.
Controls airflow between oral and nasal cavities.
Airflow Types:
Pulses for voiced sounds (e.g., “buzz”).
Continuous flow for voiceless sounds (e.g., “s” in “see”).
Voiced vowels primarily defined by three major class features:
sonorant, vocalic, and consonantal.
Nervous System Control: controls the entire process)
Coordinates muscle contractions for speech production
Timing of contractions is critical; errors can lead to misarticulation
Lips and Jaw:
Most visible articulators, involved in vowel and consonant production.
Jaw supports the tongue and lower lip movements.
Speech Production Understanding:
Involves phonology, articulatory phonetics, acoustic phonetics, and speech perception.
Discrete linguistic units (like phonemes) relate to muscle contractions for speech.
Vocal Tract: (upper airway)
Flexible tube from larynx to mouth/nose, shaped by articulator movements (speech articulation)
Distinctive Features:
A set of binary features used to describe phonemes across all languages.
Example: Nasality, which can be +nasal (nasal sound) or −nasal (non-nasal sound).
Sonorant Sounds:
Produced with an open vocal cavity allowing spontaneous voicing.
Nonsonorants (obstruents) require special mechanisms for voicing
Vocalic Sounds:
Produced with oral cavity shapes that allow for spontaneous voicing without exceeding constriction levels of high vowels.
Consonantal Sounds:
Defined by definite constriction in the midsagittal region of the vocal tract; vowels are
-consonantal.
Tongue body Features:
Vowels distinguished by size/configuration of the resonating cavity.
High sounds: tongue raised; low sounds: tongue lowered; back sounds: tongue retracted.
Rounded sounds: lips protruded; nonrounded sounds: lips not protruded.
Nasal sounds:
lowered velum allows sound through the nose.
Tense vowels:
produced with greater muscular effort (e.g., /i/, /u/).
Nontense vowels:
produced with less effort (e.g., /ɪ/, /ʊ/).
Suprasegmentals:
characteristics of speech that involve larger units such as syllables, words, phrases, or sentences (prosodic features)
Stress
the degree of effort, prominence or importance given to some part of an utterance
Intonation
the vocal pitch contour of an utterance; the way the fundamental frequency changes from syllable and even from segment to segment
Loudness
related to sound intensity or the amount of vocal effort used
Pitch level:
average pitch a speaker’s voice (high, low, medium)
Juncture
combo of intonation, pausing, and others to mark special distinctions in speech (lets eat grandma vs. Lets eat grandma!)
