AA ASR WER: Artificial Analysis ASR WER

Metric: WER (%) (lower is better)Introduced: 2024

Word Error Rate measured by Artificial Analysis using a consistent methodology across a proprietary multi-domain test suite. Provides independent, reproducible comparison across both open-source and commercial STT APIs. Lower is better. High benchmark score alone doesn't make a model the right pick — weigh it against pricing, API availability, and release date.

How to read this benchmark

This benchmark scores models where lower is better. Scores are useful for directional filtering and shortlisting — not for universal quality ranking. Prefer benchmarks closest to your workload, then validate the linked model pages for pricing, context window, and provider availability.

Trust this score when

There is a fresh timestamped snapshot (or multiple snapshots) for this benchmark.
The model list covers the same version family you can actually deploy today.
Top candidates overlap with your required routing and feature requirements.

Be cautious when

There is only one benchmark snapshot or the dataset appears stale.
The benchmark metric direction is opposite of your decision objective.
The score difference between options is narrow and likely within implementation variance.

FAQ

What does the AA ASR WER benchmark measure?

Word Error Rate measured by Artificial Analysis using a consistent methodology across a proprietary multi-domain test suite. Provides independent, reproducible comparison across both open-source and commercial STT APIs. Lower is better. On this page it lists 3 tracked model variants where lower is better.

Is a higher Artificial Analysis ASR WER score always better?

For this benchmark, lower is better. A high score helps you shortlist, but confirm pricing, context window, and provider availability on each model page before committing — the top scorer is not always the right pick for your workload or budget.

How current is this Artificial Analysis ASR WER data?

This benchmark was last reviewed on Jun 7, 2026. The tracked score average moved -1.20 points across the last 3 snapshots.
