Author:Louw, Johannes ADate:Dec 2019Recent work in sequence-to-sequence neural networks with attention mechanisms, such as the Tacotron 2 and DCTTS architectures, have brought on substantial naturalness improvements in synthesised speech. These architectures require at least ...Read more
Author:Grover, AS; Van Huyssteen, GB; Pretorius, MWDate:Jun 2011Human language technology (HLT) has been identified as a priority area by the South African government. However, despite efforts by government and the research and development (R&D) community, South Africa has not yet been able to maximise ...Read more
Author:Barnard, E; Davel, MH; Van Huyssteen, GBDate:Mar 2010Telephone-based information access has the potential to deliver a significant positive impact in the developing world. We discuss some of the most important issues that must be addressed in order to realize this potential, including matters ...Read more
Author:Louw, Johannes ADate:Dec 2020Sequence-to-sequence end-to-end models for text-to-speech have shown significant gains in naturalness of the produced synthetic speech. These models have an encoder-decoder architecture, without an explicit duration model, but rather a learned ...Read more
