What this research studies

You may be asked to try guided voice and throat techniques while researchers measure how your vocal cords move and contact. They'll use imaging (like CT) and biomechanical measurements to compare different laryngeal and vocal-tract configurations. The team will test whether the techniques that simulations predict to lower contact pressure actually do so in real people. Results could help make voice therapy more targeted and measurable.

Who could benefit from this research

Good fit: Adults (21+) with phonotraumatic vocal hyperfunction or persistent voice strain who can attend lab visits at UCLA would be ideal candidates.

Not a fit: People without hyperfunctional voice disorders, or those whose voice problems are due to structural lesions requiring surgery, may not benefit directly from these techniques.

Why it matters

Potential benefit: If successful, this work could give clinicians objective measures and clearer techniques to reduce vocal-cord injury from voice strain.

How similar studies have performed: Previous support comes mainly from computer simulations and limited experimental data, so this work is building experimental confirmation of mostly theoretical findings.
