A first-pass decoding strategy for LSTM language models in LVCSR recombines hypotheses on the last two words before lattice rescoring to achieve competitive results on Hub5'00 and Librispeech with better-than-real-time runtime.
We have shown that first using the LSTM LM with a small recombination limit and doing lattice rescor - ing afterwards yields the most efficient decoding process

LSTM Language Models for LVCSR in First-Pass Decoding and Lattice-Rescoring
A first-pass decoding strategy for LSTM language models in LVCSR recombines hypotheses on the last two words before lattice rescoring to achieve competitive results on Hub5'00 and Librispeech with better-than-real-time runtime.
