Nasality

Terms in this set (20)

does English have phonemic nasalized vowels or phonetically nasalized vowels
phonetically
vowels in nasal contexts
/ma/ /in/
velum position for nasal consonants
velum is lowered to connect to the oropharyngeal cavity so that air can flow out through the nostrils
nasalization
the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth
-form of coarticulation
excessive nasality sign of?
dysarthria
nasal cavity has its own set of resonances and damping due to:
soft tissue
nasal resonances are called?
nasal murmurs
oral cavity being closed during nasality creates an?
anti resonance
which cavities possibly contribute to articulatory distinctions between nasal sounds?
oral cavity
frequency of anti resonances highest for which nasal?
-ng
-higher frequency anti resonances produced by paranasal sinuses
distinguishing nasal consonants
1) energy reduced overall compared to oral sounds, particularly vowels
2) nasal murmurs- a resonance pattern- but peaks have broader BW and are damped
3) anti-resonances that change with place of articulation
4) formant transitions indicated by place of articulation
the most prominent nasal resonance occurs at?
300 hz
cavities that contribute to spectral features of nasal vowels
maxillary
sphenoid
front
sinuses
spectra: nasal vs. oral sounds **
reduced amplitude
extra low frequency peak
extra peak around 1,000 Hz
reduced frequency and broad bandwidth of F2
"deep" valley above 1,000 Hz
opening of the velopharyngeal port for a nasal consonant can affect the formant frequencies of:
-preceding vowels
-following vowels
-both
-neither
both
introduction of nasal resonance between?
300-500 Hz
anti-resonance of nasalized vowel at?
slightly higher frequency
F1 shifted upward/ downward due to effect of anti resonance
upward
nasalization causes overall amplitude increase/ reduction
reduction
exception to most nasalization
/i/
high place of articulation
nasality
perceptual term that quantifies the degree of nasalization
