PyannoteAI

pyannoteAI builds speaker intelligence infrastructure for voice AI: a hosted REST and WebSocket API that answers "who spoke when" (speaker diarization) and "who is speaking" (speaker identification via voiceprints) for both batch audio files and live streams. The company commercializes the widely adopted open-source pyannote.audio library, offering batch diarization, real-time streaming diarization over a WebSocket gateway, voiceprint enrollment and matching, and speech-to-text orchestration that returns speaker-attributed transcripts in a single call. Developers authenticate with a bearer API key, submit asynchronous jobs, and receive results by polling or signed webhooks.

PyannoteAI publishes 5 API contracts indexed on the APIs.io network, including Media API, Streaming API, Jobs API, and 2 more. Tagged areas include Company, Ai Data, Speech Recognition, Speaker Diarization, and Audio.

The PyannoteAI catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

PyannoteAI’s developer surface includes documentation, API reference, getting-started guide, authentication, support, engineering blog, pricing, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/pyannoteai: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Speech and Voice AI	covered	17.2 (thin)	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
