Adaptation Algorithms for Neural Network-Based Speech Recognition: An Overview

1 code implementation14 Aug 2020 Peter Bell, Joachim Fainberg, Ondrej Klejch, Jinyu Li, Steve Renals, Pawel Swietojanski

We present a structured overview of adaptation algorithms for neural network-based speech recognition, considering both hybrid hidden Markov model / neural network systems and end-to-end neural network systems, with a focus on speaker adaptation, domain adaptation, and accent adaptation.

Speaker Adaptive Training using Model Agnostic Meta-Learning

1 code implementation23 Oct 2019 Ondřej Klejch, Joachim Fainberg, Peter Bell, Steve Renals

Speaker adaptive training (SAT) of neural network acoustic models learns models in a way that makes them more suitable for adaptation to test conditions.

Acoustic Model Adaptation from Raw Waveforms with SincNet

1 code implementation30 Sep 2019 Joachim Fainberg, Ondřej Klejch, Erfan Loweimi, Peter Bell, Steve Renals

Raw waveform acoustic modelling has recently gained interest due to neural networks' ability to learn feature extraction, and the potential for finding better representations for a given scenario than hand-crafted features.

Lattice-Based Unsupervised Test-Time Adaptation of Neural Network Acoustic Models

no code implementations27 Jun 2019 Ondrej Klejch, Joachim Fainberg, Peter Bell, Steve Renals

Acoustic model adaptation to unseen test recordings aims to reduce the mismatch between training and testing conditions.

Lattice-based lightly-supervised acoustic model training

no code implementations30 May 2019 Joachim Fainberg, Ondřej Klejch, Steve Renals, Peter Bell

This text data can be used for lightly supervised training, in which text matching the audio is selected using an existing speech recognition model.

Learning to adapt: a meta-learning approach for speaker adaptation

1 code implementation30 Aug 2018 Ondřej Klejch, Joachim Fainberg, Peter Bell

The performance of automatic speech recognition systems can be improved by adapting an acoustic model to compensate for the mismatch between training and testing conditions, for example by adapting to unseen speakers.
