Voice Evaluation
This acoustic measurement gives information about breath support.
What maximum phonation time?
This simple behavior is the most important way to maintain vocal fold hydration.
What is drinking water?
These small, benign growths, often appearing in pairs, are commonly caused by vocal overuse or misuse.
What are vocal nodules?
BL20
Grade: 1
Roughness: 1
Breathiness: 0
Asthenia:0
Strain:0
This professional specializes in evaluating and treating voice disorders.
Who is a speech-language pathologist (SLP)?
During a voice assessment, this allows visualization of the vocal folds.
What is a laryngoscope (or videostroboscope)?
Excessive use of this behavior, often used to clear mucus, can cause phonotrauma.
What is throat clearing (or coughing)?
This vocal fold lesion is typically unilateral, filled with fluid, and can develop after a single traumatic vocal event.
What is a vocal polyp?
LA9021
Grade: 0
Roughness: 0
Breathiness: 0
Asthenia: 0
Strain: 0
This everyday habit—often done while watching sports or cheering—can lead to vocal fold strain.
What is yelling (or shouting)?
This perceptual scale is often used by clinicians to rate voice quality.
CAPE-V or GRBAS
Environmental factors like this—common in dusty workplaces—can dry or irritate the vocal folds.
What is poor air quality or exposure to irritants?
This neurological voice disorder results from involuntary spasms of the laryngeal muscles during speech.
What is spasmodic dysphonia?
PT014
Grade: 3
Roughness: 3
Breathiness: 0
Asthenia: 0
Strain: 2
This condition, often seen in teachers and singers, results from chronic misuse and leads to persistent hoarseness and fatigue.
What is muscle tension dysphonia (MTD)?
This aerodynamic measure reflects the efficiency of vocal fold vibration by dividing vital capacity by maximum phonation time.
What is the s/z ratio?
These two substances, found in coffee and alcohol, can contribute to dehydration of the vocal folds.
What are caffeine and alcohol?
This condition, often linked to gastroesophageal reflux, can cause redness, swelling, and hoarseness.
What is laryngopharyngeal reflux (LPR)?
PT001
Grade: 2
Roughness:1
Breathiness: 0
Asthenia: 1
Strain: 3
You observe supraglottic compression during phonation. List two possible contributing factors that might explain this compensatory behavior.
What are (1) excessive laryngeal muscle tension and (2) glottal insufficiency (e.g., due to paresis or incomplete closure)?
This is used to for therapy planning.
What is a voice evaluation?
This program of voice care includes education on hydration, voice use, and behavior modification, and is often part of voice therapy.
What is a vocal hygiene program (or voice conservation program)?
This type of dysphonia occurs when no structural or neurological pathology is present, often tied to stress or psychological factors.
What is functional (psychogenic) dysphonia?
PT120
Grade: 3
Roughness: 3
Breathiness: 1
Asthenia: 1
Strain: 2
This perceptual voice quality, often described as “rough” or “gravelly,” is typically associated with aperiodic vocal fold vibration.
