voice, as a signal
cittaa, 2026

Your voice carries

more than words.

It listens to how you sound, not only what you say, and returns a quiet reflection. A private minute, offered for now to a few.

The premise

There is tonebeneath the words.

Your pitch, your pauses, the steadiness of your voice, carries signals of how you are. Vocalysis listens to that layer, gently, and reflects it back to you alone.

The science

Measured,not guessed.

Depression and anxiety leave measurable traces in speech, in its melody, timing, and steadiness. Vocalysis rests on that research, and reads as a first impression, never a diagnosis.

0.81*
Pooled accuracy

The strongest speech models reach 0.81 accuracy, at 0.84 sensitivity, for detecting depression.

105
Studies pooled

That figure holds across 105 studies in a 2025 review, not one lab, not one dataset. The signal replicates.

Three
Acoustic families

Prosody, spectral and source features, and voice quality, read together, never one feature alone.

Yours alone

Privateby design.

Your voice is read in the moment and never kept. What returns is encrypted, and yours alone.

The invitation

For a few,to begin.

Vocalysis is opening slowly, by invitation. Leave your name, and we will reach out when a place opens for you.

Your name is with us now. We will reach out, quietly, when a place opens for you.
