Adversarial Joint Training with Self-Attention Mechanism for Robust End-to-End Speech Recognition

no code implementations3 Apr 2021 Lujun Li, Yikai Kang, Yuchen Shi, Ludwig Kürzinger, Tobias Watzel, Gerhard Rigoll

Inspired by the extensive applications of the generative adversarial networks (GANs) in speech enhancement and ASR tasks, we propose an adversarial joint training framework with the self-attention mechanism to boost the noise robustness of the ASR system.

Lightweight End-to-End Speech Recognition from Raw Audio Data Using Sinc-Convolutions

no code implementations15 Oct 2020 Ludwig Kürzinger, Nicolas Lindae, Palle Klewitz, Gerhard Rigoll

For this, we propose Lightweight Sinc-Convolutions (LSC) that integrate Sinc-convolutions with depthwise convolutions as a low-parameter machine-learnable feature extraction for end-to-end ASR systems.

MP3 Compression To Diminish Adversarial Noise in End-to-End Speech Recognition

1 code implementation25 Jul 2020 Iustina Andronic, Ludwig Kürzinger, Edgar Ricardo Chavez Rosas, Gerhard Rigoll, Bernhard U. Seeber

The present work proposes MP3 compression as a means to decrease the impact of Adversarial Noise (AN) in audio samples transcribed by ASR systems.

CTC-Segmentation of Large Corpora for German End-to-end Speech Recognition

11 code implementations17 Jul 2020 Ludwig Kürzinger, Dominik Winkelbauer, Lujun Li, Tobias Watzel, Gerhard Rigoll

In this work, we combine freely available corpora for German speech recognition, including yet unlabeled speech data, to a big dataset of over $1700$h of speech data.
