Who could benefit from this research

Could help

Children aged 0-11 with voice or coordination concerns who are seen by speech-language pathologists.

Less likely to help

Children without voice disorders or those not assessed using respiratory or aerodynamic measures may not benefit directly.

What this research studies

This project aims to make affordable, accurate measures of respiratory capacity and phonatory airflow available to speech-language pathologists. It combines acoustics, statistics, and engineering to design a low-cost device and software that estimate vital capacity and mean phonatory airflow during sustained voicing. The approach uses a vortex whistle whose frequency relates to the airflow, enabling a simple test that could fit into everyday clinical practice. The work seeks to complement existing spirometry by offering a practical tool for better voice assessment in kids with coordination or other speech-related issues.

Why it matters

Potential benefit: If successful, clinicians could better diagnose and monitor pediatric voice disorders with a lower-cost, easy-to-use device.

How similar studies have gone: This design approach builds on established relationships between airflow and voice measures, but the specific vortex whistle tool is a novel, cost-saving method.
