Chapter 2 (2.1-2.5): Phonetics Flashcards
phonetics
The inventory and structure of the sounds of speech
phones
(speech sounds) are finite in any human language
articulatory phonetics
the physiological mechanisms of speech production
acoustic phonetics
measuring and analyzing the physical properties of the sound waves we produce when we speak
International phonetic alphabet (IPA)
used for transcribing the sounds of speech, system that attempts to represent each sound of human speech with a single symbol
segments
individual phones
larynx
the sound source
vocal folds
set of muscles
vocal tract
the filter for air
pharynx
tube between the larynx and oral cavity
lungs
the source of moving air
intercostal muscles
muscles between the ribs
diaphragm
sheet of muscle separating the chest cavity from abdomen
voiceless
when vocal folds are pulled apart and make practically no sound (f, s)
voiced
when vocal folds are brought close together but not tightly closed, air passing through causes them to vibrate to produce sound (v,z)
whisper
the anterior vocal folds are pulled close together and posterior folds are pulled apart
murmur
(breathy voice) voiced but vocal folds are relaxed to allow air through
natural classes
sounds of language being grouped based on phonetic properties that they share
(Basic division among sounds- vowels & consonants)
glides
share properties of vowels and consonants (semivowel, semiconsonant), rapidly articulated vowels
consonants
made with a obstruction in the vocal tract (blocked or restricted) momentarily
vowels
produced with little obstruction in the vocal tract, more sonorous (acoustically powerful) than consonants
