    Study Notes

    Voice Disorders

    • Voice is the primary means of human expression
    • Male frequency: 125 Hz
    • Female frequency: 250 Hz
    • Child frequency: 500 Hz

    Voice Disorder Types

    • Pitch Disorders:

      • Monopitch: lack of natural pitch variation (neurological or psychiatric)
      • Inappropriate pitch: outside normal range for age/sex
      • Pitch breaks: sudden, uncontrolled changes in pitch (common in puberty)
      • Puberphonia/mutational falsetto: high-pitched voice after puberty

    • Loudness Disorders:

      • Monoloudness: lack of vocal intensity variation
      • Loudness variations: excessive variations in vocal intensity (too soft or loud)

    • Quality Disorders:

      • Hoarseness: harsh voice sounds (irregular VF vibrations)
      • Breathiness: audible air escaping during phonation (incomplete VF closure)
      • Harshness: rough, unpleasant sounds (muscle tension)

    Other Vocal Disorders

    • Vocal tremor: lack of CNS control on larynx
    • Strain/struggle & hoarseness: difficulty initiating & maintaining sound
    • Diplophonia: double sound due to different VF vibrations
    • Stridor: noisy breathing (narrow airway)
    • Aphonia: complete loss of voice
    • Unilateral vocal fold paralysis: one vocal fold is paralyzed
    • Bilateral vocal fold paralysis: both vocal folds are paralyzed

    Vocal Abuse/Misuse

    • Abuse: excessive throat clearing
    • Misuse: screaming or yelling

    Vocal Nodules & Polyps

    • Vocal nodules: localized growths on vocal folds (often bilateral)
    • Vocal polyps: fluid-filled lesions on vocal folds (often unilateral)

    Vocal Abuse/Misuse

    • Abuse: excessive throat clearing
    • Misuse: screaming, yelling

    Resonance Disorders

    • Hypernasality: sounds resonate more in the nose than the mouth
    • Hyponasality: sounds resonate less in the nose than the mouth
    • Cul-de-sac: sound trapped in the throat/nose

    Cleft Lip and Palate

    • Cleft lip: opening in the lip (unilateral or bilateral)
    • Cleft palate: opening in the palate (hard or soft palate)

    Communication Disorders (Cleft Lip/Palate)

    • Hearing loss: common due to middle ear infections
    • Speech sound disorders: errors due to structural abnormalities
    • Language disorders: initial delays, with improvement as they get older
    • Laryngeal & phonatory disorders: hyperfunction, soft voice, difficulty with feeding
