Learning a Subword Inventory Jointly with End-to-End Automatic Speech Recognition

ICASSP 2020accepted

Recent work has demonstrated the promise of using subword units as output targets for sequence-to-sequence automatic speech recognition (ASR) models. Our work builds on the latent sequence decomposition (LSD) framework, in which the use of subword units in ASR is dependent on both the speech input a…

Subword Regularization and Beam Search Decoding for End-to-end Automatic Speech Recognition

Jennifer Drexler, James R. Glass

ICASSP 2019accepted

In this paper, we experiment with the recently introduced subword regularization technique [1] in the context of end-to-end automatic speech recognition (ASR). We present results from both attention-based and CTC-based ASR systems on two common benchmark datasets, the 80 hour Wall Street Journal cor…
