This paper illustrates the work around the English - American Signs Language (ASL) data generation for the speech2signs system that is devoted to the generation of a signs language interpreter. The current work will be, first, an approximation to the speech2signs system and, second, a video-to-video corpus generator for an end-to-end approximation of speech2signs. In order to generate the desired corpus data, the Google Transformer (a Neural Machine Translation system based completely on attention) will be trained to translate from English to ASL. The dataset used to train the Transformer is the ASLG-PC12.

Speech recognition is the task aiming to identify words in spoken language and convert them into text. This bachelor{\textquoteright}s thesis focuses on using deep learning techniques to build an end-to-end Speech Recognition system. As a preliminary step, we overview the most relevant methods carried out over the last several years. Then, we study one of the latest proposals for this end-to-end approach that uses a sequence to sequence model with attention-based mechanisms. Next, we successfully reproduce the model and test it over the TIMIT database. We analyze the similarities and differences between the current implementation proposal and the original theoretical work. And finally, we experiment and contrast using different parameters (e.g. number of layer units, learning rates and batch sizes) and reduce the Phoneme Error Rate in almost 12\% relative.
