Thymia

What is Thymia?

Thymia is a voice biomarker platform that reads health and safety signals from speech rather than from the words spoken. Its models analyse patterns in pitch, rhythm, pauses and tone, which it calls neural morphemes, and return scores within seconds. The vendor says 30 or more clinical and wellbeing states can be assessed from about 15 seconds of natural speech. Two models are offered: Helios for non-clinical wellbeing and safety monitoring, covering distress, stress, fatigue, low self-esteem and burnout, and Apollo for clinical-grade depression and anxiety assessment, which is registered with the MHRA as a UKCA Class I medical device and intended for qualified healthcare professionals. Developers use a REST API for recorded audio, or Sentinel to stream biomarkers during live voice conversations. Eleven languages are supported, and the platform can be deployed on cloud or on-prem. Prices are not published; Apollo needs a separate access agreement, so contact thymia for details.
