Dysarthric speech synthesis via non-parallel voice conversion
(Universitat Politècnica de Catalunya, 2021-07-08)
Master thesis
Open AccessIn this thesis we propose and evaluate a voice conversion (VC) method to synthesise dysarthric speech. This is achieved by a novel method for dysarthric speech synthesis using VC in a non-parallel manner, thus allowing VC ... -
Efficient transformers for direct speech translation
(Universitat Politècnica de Catalunya, 2021-07)
Bachelor thesis
Open AccessIn this thesis, we propose a new approach for Speech-to-Text translation, where thanks to an efficient Transformer we can work with a spectrogram without having to use convolutional layers before the Transformer. This ... -
