We've all experienced transitory voice problems when we've had a cold, allergies, or temporary laryngitis from too much yelling or screaming.

A diagnosed voice disorder can affect a person's vocal pitch, volume, quality and/or resonance. The voice disorder may be either organic (stemming from a physical cause) or functional (no known physical cause).

Some examples of voice disorders include:
  • Vocal nodules
  • Spastic dysphonia
  • Chronic laryngitis
  • Vocal fold paralysis
  • Laryngectomy
A comprehensive voice assessment includes:
  • Pitch/frequency: Too low? Too high?
  • Volume/loudness: Too soft? Too loud?
  • Quality: Breathy? Hoarse? Harsh?
  • Resonance: Hyponasal? Hypernasal?
  • Respiratory support
  • Vocal habits and behaviours
Before a voice evaluation can be conducted, evaluation and clearance by an Ear Nose and Throat Specialist (ENT) is necessary to determine the presence or absence of any vocal pathology.
