A Deliberation-based Joint Acoustic and Text Decoder

no code implementations23 Mar 2023 Sepand Mavandadi, Tara N. Sainath, Ke Hu, Zelin Wu

We propose a new two-pass E2E speech recognition model that improves ASR performance by training on a combination of paired data and unpaired text data.

Streaming End-to-End Multilingual Speech Recognition with Joint Language Identification

no code implementations13 Sep 2022 Chao Zhang, Bo Li, Tara Sainath, Trevor Strohman, Sepand Mavandadi, Shuo-Yiin Chang, Parisa Haghani

Language identification is critical for many downstream tasks in automatic speech recognition (ASR), and is beneficial to integrate into multilingual end-to-end ASR as an additional task.

Improving Deliberation by Text-Only and Semi-Supervised Training

no code implementations29 Jun 2022 Ke Hu, Tara N. Sainath, Yanzhang He, Rohit Prabhavalkar, Trevor Strohman, Sepand Mavandadi, Weiran Wang

Text-only and semi-supervised training based on audio-only data has gained popularity recently due to the wide availability of unlabeled text and speech data.

Improving Rare Word Recognition with LM-aware MWER Training

no code implementations15 Apr 2022 Weiran Wang, Tongzhou Chen, Tara N. Sainath, Ehsan Variani, Rohit Prabhavalkar, Ronny Huang, Bhuvana Ramabhadran, Neeraj Gaur, Sepand Mavandadi, Cal Peyser, Trevor Strohman, Yanzhang He, David Rybach

Language models (LMs) significantly improve the recognition accuracy of end-to-end (E2E) models on words rarely seen during training, when used in either the shallow fusion or the rescoring setups.

Improving Tail Performance of a Deliberation E2E ASR Model Using a Large Text Corpus

no code implementations24 Aug 2020 Cal Peyser, Sepand Mavandadi, Tara N. Sainath, James Apfel, Ruoming Pang, Shankar Kumar

End-to-end (E2E) automatic speech recognition (ASR) systems lack the distinct language model (LM) component that characterizes traditional speech systems.
