Open the original- What it measures
- Common Voice is speech recorded by volunteers, so its audio is less controlled than read benchmarks. The paper names the version Common Voice 15.1. The table sits in the same paper, so the systems were compared on the same test.
- What it does not show
- One paper's runs under its own text normalization and decoding, so compare systems within this table, not with other papers' numbers. The paper gives no date per row.
