Voice Assessment Flashcards
Voice Eval Summary
MD report of VF status Medical hx Respiratory capabilities Strength of glottic closure Optimum/habitual/range of pitch Intensity & Vocal quality Endurance Sites of vocal hypertension Motor/sensory eval of CN 9, 10, 12 Audio/video recorded sample
Voice Eval: Medical Hx
Birth & neonatal period Illnesses, allergies, accidents Hospitalization medications Previous ENT evals Previous speech/psychiatric contact
Voice Eval: Behavioral Hx
Biographical info Pt description of voice d/o Other reactions Effects of voice on personal life Pt explanation of cause Onset & course of d/o
Physician Eval of VF Status:
Flexible Endoscope Nasendoscopy (also like FEES–same procedure w/o food), Nasendoscopy, Mirror laryngoscopy (reversal in image to keep in mind)
Respiratory Difficulties & Voice
SOA, reduced speech endurance, emphysema, PD, CP, clavicular breathing–>increased laryngeal tension
Speaking on residual air
Clavicular: tension in neck
Other: shallow breathing
Extraneous Respiratory Noises (Stridor)
Asthma, nasal blockage, laryngeal neoplasms, laryngeal webs, abductor paresis or paralysis of VFs
Voice Eval of Respiration:
For vegetative purposes
Adequate lung capacity for sustaining speech
Efficiency of respiration
s/z ratio
Respiratory pattern
Take a deep breath and say /a/ and time them; if they don’t, give them example
Hold /i/ at normal voice as long as they can
(Note from Baker: Embarrassment: don’t show embarrassment in front of pt; doesn’t show confidence either)
S-Z Ratio
If there’s a problem w/ voice, it’ll show up on /z/
/z/ will be much shorter
Prepubertal children 10 seconds
Adults 20 to 25 seconds (this is long; Baker calls 15 seconds normal)
No pathology ratio of 1.0
Reduced vital capacity ratio of 1.0 but reduced length for both
Vocal fold pathology 2:1 ratio poor laryngeal control for /z/
Maximum Phonation Time (MPT)
Efficiency of glottal closure & efficiency of respiratory system
Adults: 15-20 seconds
Elementary school system: 10 seconds
Deep breath and count out loud as long as you can on that breath (don’t rush though)
If they let breath out at the beginning, they’re inefficient
If people are good, can sometimes count to 35-40 on 1 breath
Decreased MPT
- Inefficient glottal control: breathiness, glottal lesions (Anything that causes a leak (not able to keep glottal control), interarytenoidal lesions, paralysis or paresis of cnx
- Inefficient respiratory functioning: insufficient respiration pattern, neurologic involvement faculty learned pattern of speaking
Eval of Muscle Coordination for Respiration Activities
- Maintain slow, gradual inspiration
- Maintain slow, gradual expiration
- Sustain production of an isolated vowel
- Read aloud sentences & phrases of varying length
- Pant like a dog
- Speak while engaging in some strenuous motor activity (lift something, etc.)
Eval of Loudness
Audiometric Eval (check hearing) Optimum loudness-subjective loud enough to be heard over background noise but not uncomfortable to listener
Etiologies of Loudness
VF paralysis Neurogenic d/o's Mass lesions of the VFs Personality disturbance Deafness
Reduced loudness—paralysis?
Procedures for Eval of Loudness
Speak in presence of music
Speak while performing different levels of physical activity
Project voice across room or large lecture hall
Move away from examiner at 10 feet distance
Trouble projecting voice?
Eval of Pitch
Sing down scale to lowest note
Sing up scale to falsetto
Determine pitch range
Describe in range of musical note (E3-C5) or as a frequency range (165-523 Hz)
Adequate for age & sex
Everyone has an optimal pitch for their larynx & a habitual pitch
Sing from lowest to highest note they can—you count the notes; give example first (may have to do “do each note after me”)
May decide it’s 2 notes & count 2 notes
Cant tell if voice sounds better lower and strain higher, etc.
Evaluation of Optimal Pitch
Voice produced most efficiently; does habitual match optimum?
3 Methods:
1. Fairbanks 1/4 or 1.3: from bottom of range
2. Uh-huh: say uh-huh 2x, then hold it out, then count to 5; habitual is counting; optimal is holding ‘huh’
3. Yawn-sigh: most relaxed a larynx can get is out of a yawn; sigh out of yawn; then count to 5; optimal is sigh
Eval of Habitual Pitch
Modal frequency level or pitch use in everyday speech
Method 1: Conversational speech or reading; passage tape recorded stop tape at various place-match pitch to a pitch pipe
Method 2: Toner II Visi- pitch
Use rainbow passage
Aphonic never has a voice; not breathy
Tension will be observed: facial grimacing, tension in neck, etc.
Eval of Voice Quality
Tape record conversation of interview
Read a standard passage
Determine quality disorders of phonation or resonance
Eval of Breathiness
Asynchronous vibration of VF, paralysis of VF, bowed VF
Can it be reduced?: Phonate different vowels while lifting, Phonate different vowels by pushing, Phonate different vowels while pulling
Spastic: harsh; Flaccid: breathy
Eval of Harshness
Neurological disease, hard glottal attack, hypertension of pharynx, use severity rating scale
Eval of Hoarseness (breathiness + harshness)
Neurological disease
Interference of the mass, compliance, & elasticity of VF
Laryngeal edema
Severity rating of degree
Eval of Glottal Fry
Frying sound @ bottom of pitch range; Everyone has a little fry when they talk at times
- Determine frequency of occurrence during reading & conversation
- Avg. duration in seconds
- Where fry occurs? End of word, phrase, sentence, etc.
- More frequently on upward or downward inflection
- Elevate pitch level
