Your voice is a work tool. Start treating it like one.
A free, 2-minute browser test — no app download, no equipment — that measures how your voice is holding up, plus a simple daily log to track vocal strain before it becomes a disorder.
How it works
1. Test
Two clinically standard measures — Maximum Phonation Time and pitch-glide range — done right in your browser using your microphone. About 2 minutes.
2. Log
After a heavy teaching or rehearsal day, log how much you used your voice and any symptoms (hoarseness, fatigue, effort). Takes 15 seconds.
3. Track
See your test results and usage log side by side over weeks and terms, so you can catch a downward trend before it turns into time off work.
Built for your job, not your hobby
Most vocal health apps on the market are built for singers working on technique. Vocal Load is built for the occupational reality of teachers, choir and worship directors, call-center and telehealth workers, and anyone else whose job requires hours of talking or leading singing — where the goal isn't a better performance, it's avoiding vocal strain that costs you a workday. Apps like Infinivox, for comparison, are built for singers working on technique — they're not wrong for that job, they're just not built for this one.
The clinical basis
Maximum Phonation Time and pitch-glide/range testing are standard, well-established measures used by speech-language pathologists and ENTs during voice assessments — not a novel or unproven mechanic. The daily usage-and-symptom log mirrors the "vocal diary" the University of Iowa's Voice Academy recommends teachers keep as clinical best practice. Read more about vocal load management.
Vocal Load is a self-monitoring tool, not a diagnostic or medical device. It doesn't replace an evaluation by a doctor or speech-language pathologist — if you have persistent hoarseness (2+ weeks), pain, or a sudden voice change, see one.
