Evaluating and reducing the distance between synthetic and real speech distributions

no code implementations29 Nov 2022 Christoph Minixhofer, Ondřej Klejch, Peter Bell

While modern Text-to-Speech (TTS) systems can produce natural-sounding speech, they remain unable to reproduce the full diversity found in natural speech data.

Mask-combine Decoding and Classification Approach for Punctuation Prediction with real-time Inference Constraints

no code implementations15 Dec 2021 Christoph Minixhofer, Ondřej Klejch, Peter Bell

In this work, we unify several existing decoding strategies for punctuation prediction in one framework and introduce a novel strategy which utilises multiple predictions at each word across different windows.

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.

Acoustic Modelling

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.
