Cards

Term
International Phonetic Alphabet
Definition
System of phonetic notation, designed to represent characteristics of speech that are distinctive in oral language.
Term
Why is the IPA helpful?
Definition
Isomorphism Problems, Pronunciations, Spellings, digraphs, silent letters, etc.
Term
Phonetics
Definition
Study of speech sounds
Term
Articulatory Phonetics
Definition
How they're produced
Term
Acoustic Phonetics
Definition
Their physical characteristics
Term
How they're perceived
Definition
Auditory (or perceptual) phonetics
Term
Morphemes
Definition
Minimal unit of meaning.
For example, the word "subnormal" would have 3, because "Sub" is it's own meaning, "norm" is it's own meaning, and "al" is it's own meaning.
Term
Phonemes
Definition

A sound segment which distinguishes morphemes.

 

For example, Bag has 3 phonemes, as it contains /b/, /a/ and /g/.

Term
Allophones
Definition

One of two or more variations of the same phoneme

 

For example, /k/ in "key" or "coo", or /p/ in pie and sport

 

Term
Syllables
Definition
A cluster of coarticulated sounds with a single vowel or diphthong with or wihtout surrounding consonants
Term
Syllable Structure
Definition

Contains an Onset and Rhyme (which contains a nucleus and coda)

 

For example, "Street" would be as such:

"Str" would be the onset, "ee" would be the nucleus, and "t" would be the coda.

As a reminder, only consonants can be onsets and codas 

Term
Open Syllable
Definition
End without a coda, or end with a vowel phoneme.

Term
Closed Syllable
Definition

Syllable that ends with a coda

Syllables that end with a consonant phoneme or a consonant cluster

Term
Consonant Cluster
Definition

A group of consonants with the same syllable

Requires you know whether the consonants are onsets, coda, or nucleus, so the word "strengths" would have multiple clusters, with "ng" "th" and "s"

Term
Prevocalic
Definition
A consonant before a vowel, such as the "t" in "tub"
Term
Intervocalic
Definition
A consonant in between vowels, such as "t" in "return"
Term
Postvocalic
Definition
A consonant after a vowel, such as "b" in "tub"
Term
Initial/Medial/Final locations
Definition
In the word "hammer", "h" is the initial syllable and word, "r" is the syllable final.  In the wrod "tone", "n" would be the final syllable.
Term
Phonemic Transcription
Definition
Identification of sound segments that have lingusitic significance, indicated with slashes "/"
Term
Phonetic Transcription
Definition
Identification of the allophone variations, indicated with brackets "[]"
Term
Broad Transcription
Definition
A transcription that does not go into great phonetic detail
Term
Narrow Transcription
Definition
A transcription that goes into great phonetic detail
Term
Dialects
Definition
A variation of a language that may rsult from isolation of one form or another
Term
Bidialectal
Definition
An individual who speaks more than one dialect
Term
New English Dialect
Definition
Backing of the /ae/, or dropping of the /r/.
Term
Southern US Dialect
Definition
reduction of the ditphthongs or overemphasis of diphthongs.
Term
Accents
Definition
Influence that one's native language has on the way they speak their second language, or a result of linguistic transfer.  Thinking of dialects is descriptive, not prescriptive.
Term
Register
Definition
Style of speech adjusted to the perceived needs of our listeners, or a change in speech type when talking to groups of varying formalities.
Term
Anatomy
Definition
The study of organs and physical structures of the body
Term
Physiology
Definition
the study of hte functions of those organs and structures, and how they interact.
Term
Respiratory system
Definition
Power and energy source (the lungs)
Term
Phonatory system
Definition
Sound/Voice system
Term
Articulatory system
Definition
Sound filter
Term
Respiratory System.
Definition
Consists of Trachea (windpipe), Bronchus (branched tubes in the lungs), alveolar sacs, and Rib Cage.  Located below "glottis".
Term
Muscles
Definition

Diaphragm - dome shaped muscle separating the chest from abdomen

Pectoralis minor - connects ribs to scapula/shoulder blades)

Intercostal muscles (between ribs)

Term
During inhalation:
Definition

Diaphragm contracts and flattens

Pectoralis and Intercostal msucles contract.  

 

This causes:

Lung volume to expand, airflow flows inward, and lung pressure drops.

Term
During Exhalation:
Definition

Diaphragm relaxes and moves up, pectoralis and intercostal muscles relax

 

This causes:

lung volume to decrease, airflow flows out of the lungs, and lung pressure increases.  

Term
Breath Cycle
Definition
One complete cycle of inhalation and exhalation.
Term
Phonatory system
Definition
Larynx or the voice box.  Contains muscles and cartilages
Term
Cartilages and muscles of larynx
Definition

Cartilages: Cricoid, Arytenoid, Thyroid, Hyoid bone, and epiglottis

 

Muscles: vocal folds, vocal cords.  About a quarter of an inch.

Term
Aerodynamic and myoelastic foces
Definition
These are the forces that open and close the vocal folds.   Airflow from lungs is occuring to make the adducted vocal folds vibrate.
Term
Aerodynamic Foce, and how vocal folds function.
Definition

Vocal folds open wne greatter subglottal pressure exists

Vocal folds closes when fast air passes trhough glottis, which causes drop in air pressure, resulting in vocal folds being sucked together.

Term
Fundamental Frequency
Definition
The rate of vocal fold vibration or the number of opening-closing cycles in a unit of time.
Term
What changes the pitch of someone's voice?
Definition
Length and mass of vocal folds.
Term
3 cavities of the Supralaryngeal system
Definition
Pharynx (throat), Oral, and nasal cavity
Term
4 structures o the Supralaryngeal system
Definition
teeth, alveolar ridge, hard palate, soft palate.
Term
4 articulators of the Supralaryngeal system
Definition
jaw, lips, tongue, and velum (soft palate)
Term
3 parts of the vocal tract
Definition
pharynx, oral, and nasal cavity
Term
Velopharengeal port
Definition
The velum at the end of the soft palate.  When it raises, it closes off the velopharengeal port, making more oral sounds, due to no air pushing through the nasal cavity. If it's lowered, the port remains open, allowing nasal sounds.
Term
Linguistic functions of articulation
Definition
Point and degree of constriction are primary conributions for generation of linguistically distinctive phonetic features of speech sound.
