# Speech Recognition and Diarization on AMI IHM Source: [Speech Recognition and Diarization on AMI IHM]() Collection index: [llms.txt]() Data updated: 2026-06-02T11:06:58.320Z Evaluation combining Speech Recognition (WER) and Speaker Diarization (DER, cpWER, tcpWER) performance on the AMI IHM dataset. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Speech Recognition and Diarization | | Dataset (including any stated split) | AMI IHM | | Metric | WER | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 6 of 6 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [WER](): Lower is better; unit: SCALAR. - [DER](): Lower is better; unit: SCALAR. - [cpWER](): Lower is better; unit: SCALAR. - [tcpWER](): Lower is better; unit: SCALAR. ## Recorded results | Method | WER | Result date | Report paper | | --- | --- | --- | --- | | VibeVoice Single-pass baseline | 19.21 | Not recorded | 6a1e63d3dbd7150506f85445 | | MURMUR: Chunked, no eviction | 19.8 | Not recorded | 6a1e63d3dbd7150506f85445 | | MURMUR: Output token eviction | 19.89 | Not recorded | 6a1e63d3dbd7150506f85445 | | MURMUR: Both eviction | 20.23 | Not recorded | 6a1e63d3dbd7150506f85445 | | MURMUR: Speech token eviction | 20.41 | Not recorded | 6a1e63d3dbd7150506f85445 | | WhisperX | 22.51 | Not recorded | 6a1e63d3dbd7150506f85445 | ### VibeVoice Single-pass baseline WER: 19.21.
