Original Abstract Submitted

two-pass automatic speech recognition (asr) models can be used to perform streaming on-device asr to generate a text representation of an utterance captured in audio data. various implementations include a first-pass portion of the asr model used to generate streaming candidate recognition(s) of an utterance captured in audio data. for example, the first-pass portion can include a recurrent neural network transformer (rnn-t) decoder. various implementations include a second-pass portion of the asr model used to revise the streaming candidate recognition(s) of the utterance and generate a text representation of the utterance. for example, the second-pass portion can include a listen attend spell (las) decoder. various implementations include a shared encoder shared between the rnn-t decoder and the las decoder.
