On Time Domain Conformer Models for Monaural Speech Separation in Noisy Reverberant Acoustic Environments

1 code implementation9 Oct 2023 William Ravenscroft, Stefan Goetze, Thomas Hain

Convolution augmented transformers (conformers) have performed well for many speech processing tasks but have been under-researched for speech separation.

On Data Sampling Strategies for Training Neural Network Speech Separation Models

no code implementations14 Apr 2023 William Ravenscroft, Stefan Goetze, Thomas Hain

In this work, the impact of applying these training signal length (TSL) limits is analysed for two speech separation models: SepFormer, a transformer model, and Conv-TasNet, a convolutional model.

Deformable Temporal Convolutional Networks for Monaural Noisy Reverberant Speech Separation

2 code implementations27 Oct 2022 William Ravenscroft, Stefan Goetze, Thomas Hain

In this work deformable convolution is proposed as a solution to allow TCN models to have dynamic RFs that can adapt to various reverberation times for reverberant speech separation.

Utterance Weighted Multi-Dilation Temporal Convolutional Networks for Monaural Speech Dereverberation

1 code implementation17 May 2022 William Ravenscroft, Stefan Goetze, Thomas Hain

It is shown that this weighted multi-dilation temporal convolutional network (WD-TCN) consistently outperforms the TCN across various model configurations and using the WD-TCN model is a more parameter efficient method to improve the performance of the model than increasing the number of convolutional blocks.

Receptive Field Analysis of Temporal Convolutional Networks for Monaural Speech Dereverberation

1 code implementation13 Apr 2022 William Ravenscroft, Stefan Goetze, Thomas Hain

A feature of TCNs is that they have a receptive field (RF) dependent on the specific model configuration which determines the number of input frames that can be observed to produce an individual output frame.
