consonants produced with a continuous airflow through the mouth accompanied by a continuous audible noise
fricatives
-
non-continuant consonants that show a slow release of the closure
affricates

involves less obstruction than a fricative but more than a vowel
approcimants
-
when the tip of the tongue makes full contact with the alveolar ridge but one side of the tongue is lowered
lateral approximant
-
the glottal state in which the vocal folds are brought close together but not tightly closed causing air passing through them to vibrate
voiced
-
the glottal state in which the vocal folds are pulled apart allowing air to pass directly through the glottis
voiceless
-
the points at which the airstream can be modified to produce different sounds
places of articulation(points of articulation)
-
features that represent place of articulation
place of articulation features
-
consonants that involve closure or constriction of the two lips
bilabials
-
sounds involving the lower lip and upper teeth (e.g the initial sounds of freedom and vintage)
labiodentals
-
sounds made with the tongue placed against or near the teeth
dentals
-
consonant sound produced with the tip of the tongue and the alveolar ridge
alveolars

sounds produced with the tongue tip in the region behind the alveolar ridge
post- alveolars

sounds produced with the tongue on or near the palate
palatals
-
sounds made with the tongue touching or near the velum
velars
-
sounds produced by using the vocal folds as the primary articulators
glottals
-
a class of sounds that shares a feature or features(e.g. voiced stops)
natural class of sounds
-
a vowel that is made with the tongue neither raised nor lowered(e.g. the vowels sounds in set and coke)
mid vowel
-
vowel produced with the tongue body neither forward nor retracted
central vowel
-
a vowel with greater constriction opposite of open
close vowel
-
a vowel with less constriction , opposite of close
open vowel
-
drawing together of the corners of the lips as in rounder vowels
rounding
-
sounds made with the lips protruding
rounded(sounds)
-
a set of muscles inside the larynx that may be positioned in various ways to produce different glottal states
vocal folds(vocal cords)
-
the oral cavity, nasal cavity and pharynx
vocal tract
-
the muscles between the ribs that help maintain the air pressure necessary for speech production
intercostals
-
the large sheet of muscle that separates the chest cavity from the abdomen and helps maintain the air pressure necessary for speech production
diaphragm
-
the tube below the larynx through which air travels when it leaves the lungs; commonly known as the windpipe
trachea
-
the cartilage that forms the main portion of the larynx spreading outward like the head of a plow
thyroid cartilage
-
the ring shaped cartilage in the larynx on which the thyroid cartilage rests
cricoid cartilage
-
two small cartilages in the larynx that are attached to the vocal folds, enabling the vocal folds to be drawn apart or together
arytenoids
-
the glottal state in which the vocal folds are adjusted so that the front portions are pulled close together while the back portions are apart
whisper
-
the glottal state that produces voiced sounds with the vocal folds relaxed enough to allow enough air to escape on to produce a simultaneous whispery effect
murmur(breathy voice)
-
vowels that do not show a noticeable change in quality during their production(e.g. the vowels sounds cab and get)
simple vowels(monophthongs)
-
a dorsal feature that characterizes sounds produced with the tongue body raised
high
-
a dorsal feature that characterizes vowels made with the tongue body distinctly lowered from a central position in the oral cavity
low
-
a vowel that is made with tongue positioned in the back of the oral cavity(e.g. the vowel sounds in hoot and board)
back vowel
-
a vowel that is made with the tongue positioned in the front of the oral cavity(e.g. the vowel sounds in seal and bat)
front vowel
-
a dorsal feature that captures the tense-lax distinction among vowels
tense
-
a vowel that is made with a placement of the tongue that results in relatively less vocal constriction(e.g. the vowel sounds in hit and but)
lax vowel
-
the lax vowel that is characterized by briefer duration than any of the other vowels(e.g. the underlined vowels in Canada,suppose)
schwa(reduced vowel)
-
one sound influencing the articulation of the other in a sequence of phonetic segments (e.g. in the sequence[pl], the tongue tip will start to move towards the alveolar ridge before the lips separate more than one articulate is active
coaticulation
-
articulatory adjustments that occur during the production of connected speech
processes
-
the influence of one segment on another resulting in a sound becoming more like a nearby sound in terms of one or more of its phonetic characteristics (e.g. in english vowels become nasal if followed by a nasal consonant)
assimilation
-
assimilation in which a sound influences a preceding segment(e.g. nasalization in english)
regressive assimilation
-
assimilation in which sound influence the following segment(e.g. liquid-glide devoicing in english)
progressive assimilation
-
a process that reduces a full vowel typically unstressed to a schwa
voicing assimilation
-
voicing assimilation in which a sound becomes voiceless because of a nearby voiceless sound(e.g. the l in place is devoiced because of the voiceless stop preceding it)
devoicing
-
an assimilation process in which a dental or aveolar stop changes to a flap in the environment of other continuants
flapping
-
a process whereby one segment becomes less like another segment in its environment
dissimilation
-
a process that removes a segment from certain phonetic contexts(e.g. the pronunciation of fifths as fifs)
deletion
-
a proces that inserts a segment into a particular environment(e.g. the insertion of a schwa in the pronunciation of athlete)
epenthesis
-
a process that recorders a sequence of segments
