Virtuosis Voice Biomarker API

Virtuosis exposes a REST API for acoustic/voice-biomarker analysis of speech recordings, delivering health, wellbeing, and communication insights. Applications upload Base64-encoded audio and poll for analysis results across types such as wellbeing, parkinsons, alzheimers, and communication_coach. Access to live API calls requires an approved organization and API key, while documentation, OpenAPI specs, llms.txt, and a hosted MCP server are publicly reachable.

Virtuosis Voice Biomarker API publishes 5 APIs on the APIs.io network, including Accounts API, Voice Biomarker Api Default API, Recordings API, and 2 more. Tagged areas include Digital Health, voice biomarkers, speech analysis, acoustic analysis, and Medical Device.

Virtuosis Voice Biomarker API’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, signup flow, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/virtuosis-voice-biomarker-api: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
