80
Q

acoustics

liquids and glides (1)

A

resemble vowels acoustically (aka semivowels) BUT has a lower amplitude than vowels d/t vocal tract constriction

81
Q

acoustics

obstruent fricatives (2)

A

narrow constriction results in turbulent airflow (aka aperiodic noise), airflow is continuous (aka friction noise)

82
Q

acoustics

obstruent stops (3)*

A

airflow is completely blocked for a brief period (aka noncontinuant), silent during the blockage then burst of energy when the blockage is released, sound source=aperiodic noise

*VOT:period of time from the beginning of the burst until the onset of voicing

83
Q

acoustics

obstruent affricates (2)

A

combine the features of stops and fricatives (aka silent blockage -> blockage released to narrow constriction -> airflow through constriction produces frication noise), sound source=aperiodic noise

84
Q

acoustics

voiced and voiceless obstruent cognates (3)

A

aperiodic noise is the primary sound source (aka no VF vibration required), voiced obstruents have shorter duration than voiceless obstruents, sound is filtered by portion of vocal tract in front of the noise source
