thymia Documentation

Helios is thymia’s mental wellness model. From just 15 seconds of natural speech, Helios analyses neural morphemes™ to produce clinical-grade biomarker scores across six dimensions of mental and physical state — in real time, on any device that captures audio.

Designed for continuous monitoring outside of clinical settings, Helios applies the same foundational voice biomarker science as Apollo, framed for operational and wellbeing contexts. It is currently deployed across healthcare providers, pharmaceutical companies, and safety-critical industries including transport, logistics, and first response.

Helios is a wellness monitoring tool and is not a regulated medical device. It is not intended for clinical diagnosis or to replace clinical judgement. For clinical assessment of depression and anxiety, see Apollo.

What Helios measures

Helios returns scores across six biomarker dimensions. Each score reflects a distinct aspect of the user’s mental and physical state at the time of recording:

Biomarker	Description
`mentalStrain`	Overall measure of mental wellness — the composite signal across all dimensions
`distress`	Levels of worry, nervousness or feeling on edge
`stress`	How anxious or wound up the user may feel; ability to relax
`exhaustion`	Physical and mental tiredness resulting from manual or cognitive labour
`sleepPropensity`	Likelihood of falling asleep if given the opportunity; linked to sleep quality
`lowSelfEsteem`	How confident and capable the user feels in themselves

Each score is returned in two forms — a bucketed value and a continuous value. See Interpreting Results for a full explanation.

Use cases

Helios is architecture-agnostic and integrates into any platform or workflow that handles voice. Common use cases include:

Industry	Application
Safety-critical	Real-time fatigue and impairment monitoring for drivers, pilots, and operators
Healthcare	Continuous wellness monitoring for patients between appointments
Pharmaceutical	Longitudinal wellbeing tracking across clinical trial participants
Contact centres	Operator wellness and burnout detection during live interactions
