Normal Voice Flashcards
what is a normal voice
- normal feeling (abnormal feelings = strain in the throat when sick or voice disorder)
- age appropriate
- gender appropriate
kinds of communication
- painting,
- drawing
- body language
- gestures
- singing
- behavior
- sign language
myoelastic-aerodynamic theory of voice production
- myo = muscle
- elastic = mucosal layer + vocalis
- aerodynamic = air pressure + flow
subsystems of speaking
- respiratory system (lungs)
- voicing (larynx)
respiratory cycle
- inhalation
- exhalation
- phonation (voiced/voiceless)
inhalation
- ribcage expands
- diaphragm lowers
- lower pressure = air drawn in
exhalation
- elastic recoil
- diaphragm relaxes
- higher pressure = air pressed out
is inhalation or exhalation relatively shorter in phonation
inhalation (exhalation is relatively longer)
resonance
- sound waves are bouncing around our mouth
- amplification, richness, and voice quality
what is responsible for voice uniqueness
resonance
source-filter theory
- source = voice box
- filter = teeth, mouth, nose, sinus
when speech goes wrong usually it is …
a nerve problem
voicing muscle innervation
- recurrent laryngeal nerve
- except for cricothyroid (superior laryngeal nerve)
vocal adduction muscles
- thyroarytenoid muscles
- lateral cricoarytenoid muscles
- inter-arytenoid muscles (transverse and oblique)
vocal abduction muscle
posterior cricoarytenoid muscle
pitch and tension muscles
- vocalis muscle
- cricothyroid muscle
high amplitude (vocal fold appearance)
- vocal cords long, thin
- narrow glottis
- open and close faster
low amplitude (vocal fold appearance)
- vocal cords short, fat
- wide glottis
- open and close slower
cismale frequency range
100-140 Hz
gender neutral frequency range
145-175 Hz
cisfemale frequency range
180-220 Hz
is asymmetry needed for a normal voice
no, asymmetry presents as a voice disorder
periodicity
regular vocal fold movements
when is periodicity not established
- initiation of voice
- stopping voice
- reduced breath support
