Table 4: Comparison of joint DA error rates.
['Model', 'WER', 'DAER ( [ITALIC] h=1)', 'DAER ( [ITALIC] h=5)']
We also conducted experiments with ground-truth inputs and realized that much of the degradation comes from ASR errors rather than segmentation errors. The unified model improves the DAER by relatively 2.9% with a history length of 5.
