Efficient acoustic feature transformation in mismatched environments using a Guided-GAN
Walter Heymans, Marelie H. Davel, Charl van Heerden
We propose a new framework to improve automatic speech recognition (ASR) systems in resource-scarce environments using a generative adversarial network (GAN) operating on acoustic…
Multi-style Training for South African Call Centre Audio
Walter Heymans, Marelie H. Davel, Charl van Heerden
Mismatched data is a challenging problem for automatic speech recognition (ASR) systems. One of the most common techniques used to address mismatched data is multi-style training (…
Exploring layerwise decision making in DNNs
Coenraad Mouton, Marelie H. Davel
While deep neural networks (DNNs) have become a standard architecture for many machine learning tasks, their internal decision-making process and general interpretability is still…
