Module 2 Chapter 2 Vocab Terms Flashcards
(20 cards)
articulatory phonetics
subfield of phonetics concerned with the production of speech sounds
acoustic phonetics
subfield of phonetics concerned with physical characteristics of the sounds of speech (transmission)
auditory phonetics
subfield of phonetics concerned with the perception of speech sounds
monophthong
a simple vowel , composed of a single configuration of the vocal organs
diphthong
a complex vowel, composed of a sequence of two different configurations of the vocal organs
articulatory description
for an auditory vocal language, the description of the motion or positioning of the parts of the vocal tract that are responsible for the production of a speech sound
segmental feature
phonetic characteristic of speech sounds such as voicing, place of articulation, rounding
voicing
vibration of the approximated vocal folds caused by air passing through them. When the vocal folds vibrate a voiced sound is produced, when they do not vibrate a voiceless sound is produced
spectrogram
a three-dimensional representation of sound in which the vertical axis represents frequency, the horizontal axis represents time, and the darkness of shading represents amplitude
voicing bar
the dark band at the bottom of a spectrogram that indicates that a sound is voiced
place of articulation
the place in the vocal tract where the constriction for the production of speech sound is made
manner of articulation
term used to refer to how the airstream is modified by the articulators in the vocal tract to produce a sound
fricative
a sound made by forming a nearly complete obstruction of the airstream so that when air passes through the small passage, turbulent airflow is produced
affricate
sound produced by complete obstruction of the airflow followed by a slight release of the obstruction, allowing frication. An affricate can be thought of as a combination of a stop and a fricative
glide
sound produced with a constriction in the vocal tract that is only slightly more constricted than that of vowels
stops
sound produced by completely obstructing the airstream in the oral cavity and then quickly releasing the constriction to allow the air to escape.
nasal speech sound
sound produced by making a complete obstruction of the airflow in the oral cavity and lowering the velum to allow air to pass through the nasal cavity
liquids
consonant sound produced by an obstruction of airflow that is less narrow than that of stops on fricatives, but more narrow than that of glides
flap
a sound produced by bringing two articulators together very quickly
co-articulation
the adjustment of articulation of a segment to accommodate the phonetic environment it is produced it
