What this research studies

Many people with voice problems might also have issues with how they breathe and use air when speaking. Currently, the tools to measure these aspects are often very expensive, meaning not all voice specialists can use them. This project is creating a unique, low-cost device called a 'vortex whistle' along with special software to accurately measure your breathing capacity and how air flows when you make sounds. This new system aims to give your voice specialist a much clearer picture of how your breathing affects your voice, helping them better understand and address your specific voice concerns.

Who could benefit from this research

Good fit: Patients who experience voice disorders and need a comprehensive evaluation of their respiratory and phonatory airflow would be ideal candidates.

Not a fit: Patients whose voice problems are not related to respiratory capacity or airflow, or those not seeking voice evaluation, may not directly benefit from this specific tool.

Why it matters

Potential benefit: If successful, this new tool could lead to more accurate and accessible voice evaluations, helping more people receive appropriate care for their voice disorders.

How similar studies have performed: While the concept of using vortex whistles for airflow measurement exists, this specific application and optimization for clinical voice evaluation is a novel approach.
