Voice and Fluency Disorders
Voice
Understand normal voice parameters: pitch, loudness, quality, resonance. Know common disorders-vocal fold nodules (bilateral, phonotrauma), polyps, edema, muscle tension dysphonia, spasmodic dysphonia, and vocal fold paralysis. Know that vocal hygiene, hydration, and voice rest are foundational, and that behavioral voice therapy (e.g., resonant voice, flow phonation) is first-line for many functional disorders. Recognize red flags: persistent hoarseness over three weeks, especially in smokers, warrants medical referral before therapy.
Fluency
Know developmental stuttering: repetitions, prolongations, blocks, secondary behaviors, and avoidance. Understand that stuttering is multifactorial (genetic, neurological, environmental). Know that early intervention (e.g., Lidcombe program) is effective in preschool children. For adults, fluency shaping and stuttering modification (e.g., easy onset, pull-outs, cancellations) are core techniques. Differentiate cluttering (rapid, disorganized speech) from stuttering.
Traps in questions
A trap is beginning voice therapy before medical clearance-always rule out pathology first. Another is assuming stuttering is caused by anxiety or parenting; it is not. Also avoid recommending "just slow down" as a complete intervention. Distinguish cluttering from stuttering; the two can co-occur.
Rule of thumb
For voice: medical evaluation first, then behavioral therapy. For fluency: match the approach to age-indirect/early for preschoolers, direct techniques for older clients.
Worked example: A teacher with three months of hoarseness and a smoking history should be referred to ENT before any voice therapy begins.
