pyannote-core
Advanced data structures for handling temporal segments with attached labels
Decision gist · record as of 2026-08-14
Yes, if you are building speaker diarization or audio annotation systems. The package provides essential data structures for temporal segment handling and integrates well with the scientific Python ecosystem. However, verify the license status before use, and note that maintenance appears to be in a slower phase (332 days since last release)—acceptable for stable infrastructure but worth monitoring if you depend on active development.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.10
- Low install friction with a pure-Python wheel distribution.
- Maintenance status is aging (332 days since last release), though the package has been in development since 2014 and supports current Python versions (>=3.10).

What it is and what it does
pyannote.core is a library for working with temporal segments and their associated labels—the core data abstraction for speaker diarization, audio annotation, and time-based event tracking. It builds on numpy, pandas, and sortedcontainers to provide efficient handling of overlapping and non-overlapping time intervals, making it a foundation for speech processing pipelines and annotation workflows.
The package is part of the larger pyannote ecosystem and is typically used as a dependency rather than standalone. It offers both programmatic APIs for manipulating temporal data and optional Jupyter notebook visualization support. With low install friction and support for modern Python versions, it integrates readily into existing scientific Python stacks.
Use it for
- Build speaker diarization pipelines that track speaker identity across time intervals in audio
- Manage time-based annotations and labels for audio or video processing workflows
- Represent and query overlapping or adjacent temporal segments in event-driven systems
- Visualize temporal data and segment boundaries in Jupyter notebooks for exploratory analysis
- Integrate temporal data handling into speech processing or audio analysis frameworks
