- dc.description.abstract This work presents the first investigation intoSpontaneous Isolated Sign Language Recog-nition for Catalan Sign Language (LSC). Our work is grounded on the derivation of a dataset of signs and their glosses from a corpus of spon-taneous dialogues and monologues. The recog-nition model is based on a Multi-Scale GraphConvolutional network fitted to our data. Results are promising since several signs are recognized with a high level of accuracy, and an average accuracy of 71% on the top 5 predicted classes from a total of 105 available. An interactive interface with experimental results is also presented. The data and software are made available to the research community.
- dc.description.sponsorship We are grateful to the reviewers for their useful comments which contributed to improvement of the present work. We would like to thank specially José Luis Alba Castro from Universidade de Vigo for useful discussions which helped ground the current work. We are indebted to Gemma Barberà and Josep Quer from Universitat Pompeu Fabra for sharing a version of the Catalan Sign Language corpus before its official release which helped jumpstart our project. Finally, we acknowledge support from the Spanish State Research Agency under the Maria de Maeztu Units of Excellence Programme (CEX2021-001195-M).
