The AMI Meeting Corpus IHM subset consists of ~100 hours of recorded English meetings captured with individual headset microphones. Long-form spontaneous speech across overlapping speakers makes it a standard stress-test for ASR systems beyond clean read speech.
Wer is the reported evaluation metric for AMI-IHM. Codesota tracks published model scores on this metric so readers can compare state-of-the-art results across sources and model families.
Lower is better
Muted rows were not state of the art when published — an earlier or same-year result already scored better.
