CATOTRON – A Neural text-to-speech system in catalan. In: Proceedings of Interspeech 2020; 2020 Oct 25-29; Shanghai, China. [Baixas]: ISCA; 2020. p. 490-1.1990-9772http://hdl.handle.net/10230/45715Comunicació presentada a Interspeech 2020 celebrat del 25 al 29 d'octubre de 2020 a Shanghai, Xina.We present Catotron, a neural network-based open-source speech synthesis system in Catalan. Catotron consists of a sequence-to-sequence model trained with two small opensource datasets based on semi-spontaneous and read speech. We demonstrate how a neural TTS can be built for languages with limited resources using found-data optimization and crosslingual transfer learning. We make the datasets, initial models and source code publicly available for both commercial and research purposes.application/pdfeng© 2020 ISCAinfo:eu-repo/semantics/conferenceObjectText-to-speechSequence-to-sequenceCatalaninfo:eu-repo/semantics/openAccess
