"She'd been careful about how loud she sang. She hadn't been careful about how much."
A choir director lost her voice on day two of a three-day festival. No screaming, no illness. Just cumulative load she couldn't see coming.

The Science
VoxCheck is built on peer-reviewed vocal science, not generic wellness tracking. Here's what makes it different.
Based on Titze et al. (2003), VoxCheck tracks cumulative mechanical stress on vocal fold tissue — not just volume. The number that actually predicts injury.
Cepstral Peak Prominence detects when you've shifted from healthy flow phonation to damaging pressed phonation — even at the same volume — and corrects your load score upward.
In noisy environments, you involuntarily raise your vocal output. You don't feel it happening. VoxCheck measures ambient noise before each session and corrects for this reflex automatically.
Who It's For
Classical, musical theatre, choral, contemporary. Track session load across rehearsals and performances.
High talking load across a full teaching day. See your cumulative load in real time.
High ambient noise, multi-day festivals, season risk. The Lombard correction was built for you.
Between-session data for voice patients. Science-grounded metrics your clinical training will recognise.
