Sources & snapshots

Get the text-to-speech benchmark data

Every ranking this site has ever shown is an immutable snapshot: the raw board scores, the alias mappings that were applied, and the rules the composite was computed with. Download any of them as JSON — re-running the published formula over a snapshot reproduces the exact board it rendered.

The boards

Snapshot archive

Snapshots are append-only. Each file contains boards (source list, status, normalization strategy, board size), models (raw scores per board, aliases applied, metadata), and rules (the scoring mode, board authorities, and the dataset constants the score was computed with). Ranks and the BPRA score are recomputed from these values — nothing pre-baked, nothing editable after the fact.
