Phonetics Flashcards
Articulatory process
Airstream mechanisms + phonation + articulation
Acoustic process
Vibration of air molecules at different frequencies & amplitudes
Perceptual process
Auditory processing & mental categorization
Segments
Individual speech sounds (phones)
International Phonetic Alphabet
Universal system for transcribing the sounds of speech
3 steps of speech production
- Air supply sets air in motion (ex. lungs)
- A sound source (ex. larynx) modulates air flow via vocal folds
- Filters (ex. pharynx, oral cavity, nasal cavity) modify sound called the vocal tract
Airstream Mechanisms
Usually expressed as air expelled out from lungs (egressive airflow), but can also be produced by inhaling (ingressive airflow)
Larynx
Complex structure of cartilage, muscle, and tissue where vocal folds are located
Glottis
Space between vocal folds
Voiceless
Vocal folds are pulled apart
Voiced
Vocal folds are brought together
Murmur/ Breathy Voice
Vocal folds are partially open, letting air pass through, but still vibrating
Creaky Voice
Vocal folds are compressed and slack
Types of speech sounds
Consonants & Vowels
Articulatory differences b/n vowels and consonants
Consonants: constrict vocal tract
Vowels: open vocal tract
Aerodynamic differences b/n vowels and consonants
Consonants: no or turbulent airflow
Vowels: open vocal tract
Acoustic differences b/n vowels and consonants
Consonants: Less acoustic energy
Vowels: More acoustic energy
Stops (def)
Stopping airflow
Fricatives (def)
Constricting airflow to create turbulent noise
Affricates (def)
Stop and fricative in fast succession
Nasal (def)
Oral stop and diverted airflow to another resonator
Approximants & laterals (def)
Partial constriction without turbulence

Monophthongs
“Simple vowels”: position of articulators is relatively constant
Diphthongs
Sequence of a vowel + glide or vice versa; involves a noticeable change in articulation, but is counted as one segment only.
Syllable
Speech unit larger than a single sound and smaller than a word
Stress
Syllables said to be more prominent than others in an utterance
Tone
Languages use pitch difference to signal differences in word meaning.
Intonation
Pitch contrast to convey post lexical meanings
Falling Tune
Fall from final high accent to a low boundary tone at the end of an intonational phrase
Low Rising Tune
Fall from a final high accent to a low boundary tone at the end of an intonational phrase
