Phonetics Flashcards
Primary Vocal Organs
Lungs, Trachea, Larynx, Pharynx, Oral Cavity, Nasal Cavity
3 mechanisms of speech production
Respiration, Phonation, Articulation
Respiration
energy source of air supply, air pressure is maintained by the intercostals and diaphragm, many speech sounds are pulmonic egressive (sound that comes from air flowing out)
Articulation
the sound filter, how sound is modified into speech
Phonation
the sound source - converts air flow to sound, air flows up the trachea -> larynx -> vocal folds and vibrate (which change into different glottal states)
Glottal States
Vocal fry, Falsetto, Modal, Voiceless, Voiced, Whisper, Murmur
Falsetto
vocal folds are pressed together leaving a think space for air to leave - high pitch
Modal
regular speech sound - combination of voiced and voiceless
Voiceless
When the vocal folds are pulled apart and air can pass through the glottis with no interference - initial sound of fish
Voiced
When the vocal folds are pulled close but not completely together - air passes through and vibrates (initial sound of zip)
Whisper
voiceless sound - vocal folds are adjusted so that the front portions ate pulled close and the back are apart
Murmur
breathy voice - voiced sounds abut are relaxed enough to allow air to escape (initial sound of ghee)
Main Speech Organs
lungs, vocal cords, tongue, teeth, lips, nose
lungs
supply air for speech
vocal cords
produce vibrations for speech sounds
tongue
articulates vowels and consonants
teeth
provides place of articulation for consonants
lips
articulates vowels and consonants
nose
provides nasal resonance during speech
Sound classes
vowels, consonants, glides (share properties of both V and C)
Articulatory difference
with vowels there is very little obstruction in the vocal tract and are usually voiced.
with consonants there may be a complete or narrowing closure, air is usually restricted, may be voiced or voiceless
Acoustic Difference
Vowels are more sonorous and we percieve them as longer lasting and louder
syllable
peak of sonority surrounded bt less sonorous segemnets (we count the syllables in words by the main vowels - laughing = 2)
Nucleus
a vowel is sometimes referred to as the nucleus of the syllable
glides
rapidly articulated nonsyllabic segement - produce the articulation of a vowel but quickly terminate or move to another articulation (end sound in boy or initial sound in wet)
Tongue articulation
tip, blade, body, back, dorsum, root
tip of tongue
narrow area ay the front
