Coval/Openbenchmarks Live STT — Average WER Leaderboard
Independent live speech-to-text benchmark on pinned, versioned datasets under production-realistic conditions. Word Error Rate (WER) is lower-is-better.
What this benchmark does—and does not—measure
This leaderboard preserves the benchmark's own metric, source and test date. Results are comparable only within the same benchmark definition and semantic class; missing data is never treated as a zero.

What to keep in mind
A benchmark is one evidence signal, not a universal product verdict. Test conditions, benchmark versions, source methodology and date can all affect interpretation. Compare shared benchmarks and current product evidence before making a model or tool decision.
Why dates and sources are shown
AI Orbit retains the source and tested date for each verified result so readers can judge whether evidence is current enough for their use case. Older evidence is not silently presented as a new test.
