In this thesis, we propose a multitask learning based method to improveNeural Sign Language Translation (NSLT) consisting of two parts, a tokenizationlayer and Neural Machine Translation (NMT) The tokenization part focuses on how Sign Language videos should be represented to be fed into the otherpart . We aim to develop a generic sign-level tokenization layer sothat it is applicable to other domains without further effort . We succeed in enabling knowledge transferbetween SLs and improve translation quality by 5 points in BLEU-4 and 8 points in ROUGE scores . Apart from these, we adopt3D-CNNs to improve efficiency in terms of time and space . Lastly, we discussthe advantages of Sign Language tokenization over gloss-leveltokenization over the advantages of sign-to-texting over the tokenization . To sumup, our proposed method eliminates the need for gloss level annotation to obtain higher scores by providing additional supervision by utilizing weaksupervision sources. Apart fromThese, we adopted3D CNNs to improved efficiency
