pyannote.audio

What pyannote.audio sends out of your computer by default, when, to whom, and the switch that stops it, version by version, with how we know.

The answer

Per its README and the telemetry config shipped in the package at tag 4.0.7, not run: when a pipeline or model is loaded, pyannote.audio sends usage metrics to otel.pyannote.ai naming where the pipeline came from (an official pyannote name, 'huggingface' or 'local') and its Python class, and for each file it processes the file's duration and the speaker-count settings, the shipped config turning this on by default; PYANNOTE_METRICS_ENABLED=0, set before the program starts (or set_telemetry_metrics in Python), stops it.

Version: 4.0.7 · the source at tag 4.0.7
Where the evidence came from: not run: the source applies to every platform
On by default?: yes · read in its shipped config and its own documents
Measured here?: no · read in code

Why we say so: the telemetry config shipped in the package and the README's Telemetry section read at tag 4.0.7; the sending code was not enumerated

Each call out

pipeline metrics · 4.0.7

Version · build: 4.0.7 · the source at tag 4.0.7 · not run: the source applies to every platform · not installed: source read at tag 4.0.7
Sends by default: yes · read in its shipped config and its own documents
Kind: reports
Trigger: as a side effect of a local request
When: Per its README and its shipped config at 4.0.7: when a pipeline is loaded and for each file it processes; not run.
Where: vendor telemetry collector · otel.pyannote.ai
What it sends: where the pipeline came from (an official pyannote name, 'huggingface', or 'local') and its Python class (usage); each file's duration and the speaker-count settings (usage)
The vendor's stated purpose: “With the optional telemetry feature in `pyannote.audio`, you can choose to send anonymous usage metrics to help the `pyannote` team improve the library.” — its README at tag 4.0.7, the Telemetry section's opening sentence (line 114); the shipped config (src/pyannote/audio/telemetry/config.yaml, line 1) sets metrics_enabled: true, read 2026-10-11
Grade and method: read · the telemetry config shipped in the package and the README's Telemetry section read at tag 4.0.7; the sending code was not enumerated · read 2026-10-10
Receipts: the shipped config: metrics on, and the endpoint · the README's Telemetry section

The switch

PYANNOTE_METRICS_ENABLED=0

Accepted values: 0
What it is: environment variable
Where it must be set: in the environment of the program, before it starts (see Turn them off) · turn them off
Other spellings: set_telemetry_metrics in Python, for the session or across sessions
Proof: documented; not tested by us
For the call: pipeline metrics · 4.0.7
