Since mid-2022 I’ve been continuously recording my own voice — more than 2,000 tests, every recording stored pseudonymously. Here I share weekly what we find in this data.
Observations, not marketing.

One night out. Four days to sound like me again.
I record my own voice every day, and have done so for years. After one evening of drinking and about six hours of sleep, the numbers moved in a very consistent way — and took exactly four days to fully settle back to baseline.

The harder the week, the clearer my voice.
That’s the pattern showing up after 2,000+ recordings of my own voice since 2022: multi-day stretches of work stress don’t roughen my HNR. They push it up. This month, to a personal high.

When a single outlier becomes a pattern.
One data point can be noise. But when deviations occur repeatedly within a short episode — that’s when something is actually happening.
A single outlier? Could be measurement noise. Three in a row? That’s a pattern worth

My normal is not zero.
If I measured my voice for the first time today, the result would say: rough voice. But I’ve been measuring for over four years — more than 2,000 tests. And what that data shows me is something different: that’s just my voice.
Zero is not automatically normal. Normal is what is stable and recurring for you. Recurring deviations are what’s interesting.

One voice, over four years.
Since mid-2022 I’ve been continuously recording my own voice — more than 2,000 tests, every recording stored pseudonymously. Not because I wanted to build a product. But because of a question that wouldn’t let go: what does our voice actually reveal about us, over time?
Does every person carry a biomarker with them every day — in their voice?
