Learning Hidden Unit Contributions for Unsupervised Acoustic Model Adaptation
TABLE XII: WER(%) on Switchboard eval2000.
['Model', 'eval2000 SWB', 'eval2000 CHE', 'eval2000 TOTAL']
On Switchboard, in contrast to other corpora, we observed that test-only The SI system has a WER of 21.7% compared with 20.7% for the test-only LHUC and 20.2% for the SAT-fMLLR system. The improvement obtained using test-only LHUC is comparable to that obtained with other test-only adaptation techniques, e.g. feature-space discriminative linear regression (fDLR) SAT trained feature transform models.
