Query: Lattice-Free MMI Adaptation Of Self-Supervised Pretrained Acoustic
  Models   In this work, we propose lattice-free MMI (LFMMI) for supervised adaptation
of self-supervised pretrained acoustic model. We pretrain a Transformer model
on thousand hours of untranscribed Librispeech data followed by supervised
adaptation with LFMMI on three different datasets. Our results show that
fine-tuning with LFMMI, we consistently obtain relative WER improvements of 10%
and 35.3% on the clean and other test sets of Librispeech (100h), 10.8% on
Switchboard (300h), and 4.3% on Swahili (38h) and 4.4% on Tagalog (84h)
compared to the baseline trained only with supervised data.
