Models

All signs are classified by evidence tier (Established, Emerging, or Investigational) based on published voice-based studies using acoustic analysis of human speech. The table below lists all available sign IDs and their evidence tiers. For full descriptions and per-bundle sign lists, see Models reference.

For the as-is disclaimer and how tiers fit together, see Introduction.

Available Signs

Each name in the table corresponds to an entry in the signals array of a model job result, or the signal object of a sign job result. For example:

{"name": "stress", "label": "Stress", "score": 0.81, "level": "elevated", "flagged": true}

See Response Schema for the full signals field reference.

Named Model Sign Composition

Each named model bundles a specific set of signs. The name values returned in signals[] correspond to the signs in the bundle for that model.

Model	Signs
`apex`	`head-impact`, `cognitive-load`, `fatigue`, `dehydration`, `stress`, `anxiety`, `cardiovascular-strain`
`aria`	`elevated-androgens`, `iron-deficiency`, `dehydration`, `mood-disruption`, `fatigue`, `anxiety`, `elevated-blood-pressure`
`breath`	`airway-obstruction-pattern`, `allergy`
`clarity`	`cognitive-impairment`
`harbor`	`alcohol-use-pattern`, `substance-use-pattern`, `emotional-destabilization`, `anxiety`, `stress`
`haven`	`mood-disruption`, `anxiety`, `stress`, `hypervigilance`, `attention-dysregulation`, `fatigue`
`pulse`	`mood-disruption`, `anxiety`, `stress`, `fatigue`, `dehydration`, `elevated-blood-pressure`
`tide`	`elevated-blood-pressure`, `metabolic-load`, `dehydration`, `iron-deficiency`, `fatigue`
