Sign Language Typology Series
SIGN LANGUAGE TYPOLOGY SERIES The Sign Language Typology Series is dedicated to the comparative study of sign languages around the world. Individual or collective works that systematically explore typological variation across sign languages are the focus of this series, with particular emphasis on undocumented, underdescribed and endangered sign languages. The scope of the series primarily includes cross-linguistic studies of grammatical domains across a larger or smaller sample of sign languages, but also encompasses the study of individual sign languages from a typological perspective and comparison between signed and spoken languages in terms of language modality, as well as theoretical and methodological contributions to sign language typology.

Wordlists and stories were collected in several towns of Nepal from Deaf school leavers who were considered to be representative of the Nepali Deaf. In each city or town there was a school for the Deaf either run by the government or run by one of the Deaf Associations. The wordlists were transcribed by hand using the SignWriting orthography. Two other places were visited where it was learned that there were possibly unique sign languages, in Jumla District, and also in Ghandruk (a village in Kaski District). -
Sign Language Endangerment and Linguistic Diversity Ben Braithwaite
RESEARCH REPORT Sign language endangerment and linguistic diversity Ben Braithwaite University of the West Indies at St. Augustine It has become increasingly clear that current threats to global linguistic diversity are not re - stricted to the loss of spoken languages. Signed languages are vulnerable to familiar patterns of language shift and the global spread of a few influential languages. But the ecologies of signed languages are also affected by genetics, social attitudes toward deafness, educational and public health policies, and a widespread modality chauvinism that views spoken languages as inherently superior or more desirable. This research report reviews what is known about sign language vi - tality and endangerment globally, and considers the responses from communities, governments, and linguists. It is striking how little attention has been paid to sign language vitality, endangerment, and re - vitalization, even as research on signed languages has occupied an increasingly prominent posi - tion in linguistic theory. It is time for linguists from a broader range of backgrounds to consider the causes, consequences, and appropriate responses to current threats to sign language diversity. In doing so, we must articulate more clearly the value of this diversity to the field of linguistics and the responsibilities the field has toward preserving it.* Keywords : language endangerment, language vitality, language documentation, signed languages 1. Introduction. Concerns about sign language endangerment are not new. Almost immediately after the invention of film, the US National Association of the Deaf began producing films to capture American Sign Language (ASL), motivated by a fear within the deaf community that their language was endangered (Schuchman 2004). -

Special thanks to Abby White, Deaf and Hard of Hearing Educator, Ohio School for the Deaf American Sign Language (ASL) is the official language used mostly by deaf and hard of hearing people who are immersed in the deaf community. The deaf community includes deaf and hard of hearing people, ASL interpreters and hearing people who use ASL and are familiar with deaf culture. Different sign languages such as French, Japanese, British and many more are used all over the world. ASL and its users have influenced our world. For bilingual, using ASL and English for all instruction, and instance, William “Dummy” Hoy (born in 1862) was is located in Washington, D.C. the first deaf baseball superstar and a graduate of As ASL became recognized as a language, it cleared the Ohio School for the Deaf.

What Sign Language Creation Teaches Us About Language Diane Brentari1∗ and Marie Coppola2,3
Focus Article What sign language creation teaches us about language Diane Brentari1∗ and Marie Coppola2,3 How do languages emerge? What are the necessary ingredients and circumstances that permit new languages to form? Various researchers within the disciplines of primatology, anthropology, psychology, and linguistics have offered different answers to this question depending on their perspective. Language acquisition, language evolution, primate communication, and the study of spoken varieties of pidgin and creoles address these issues, but in this article we describe a relatively new and important area that contributes to our understanding of language creation and emergence. Three types of communication systems that use the hands and body to communicate will be the focus of this article: gesture, homesign systems, and sign languages. The focus of this article is to explain why mapping the path from gesture to homesign to sign language has become an important research topic for understanding language emergence, not only for the field of sign languages, but also for language in general. © 2012 John Wiley & Sons, Ltd.

IRB protocol # 13090619 iii ABSTRACT They Have To See Us: an Ethnography of Deaf People in Tanzania Jessica Lee Department of Anthropology Thesis directed by Professor J. Terrence McCabe This dissertation explores the relationship between Tanzanian deaf people and mainstream society, as well as dynamics within deaf communities. I argue that deaf people who do participate in NGOs and other organizations that provide support to deaf people, do so strategically. In order to access services and improve their own lives and the lives of their families, deaf people in Tanzania move comfortably and fluidly between identity groups that are labeled as disabled or only as deaf. Through intentional use of the interventions provided by various organizations, deaf people are able to carve out deaf spaces that act as places for transmission of information, safe areas to learn and use sign language, and sites of network and community development among other deaf people. -
Sign Classification in Sign Language Corpora with Deep Neural Networks
Sign Classification in Sign Language Corpora with Deep Neural Networks Lionel Pigou, Mieke Van Herreweghe, Joni Dambre Ghent University flionel.pigou, mieke.vanherreweghe, [email protected] Abstract Automatic and unconstrained sign language recognition (SLR) in image sequences remains a challenging problem. The variety of signers, backgrounds, sign executions and signer positions makes the development of SLR systems very challenging. Current methods try to alleviate this complexity by extracting engineered features to detect hand shapes, hand trajectories and facial expressions as an intermediate step for SLR. Our goal is to approach SLR based on feature learning rather than feature engineering. We tackle SLR using the recent advances in the domain of deep learning with deep neural networks. The problem is approached by classifying isolated signs from the Corpus VGT (Flemish Sign Language Corpus) and the Corpus NGT (Dutch Sign Language Corpus). Furthermore, we investigate cross-domain feature learning to boost the performance to cope with the fewer Corpus VGT annotations. Keywords: sign language recognition, deep learning, neural networks 1. Introduction In previous work (Pigou et al., 2015), we showed that deep neural networks are very successful for gesture recognition SLR systems have many different use cases: corpus anno- and gesture spotting in spatiotemporal data. Our developed tation, in hospitals, as a personal sign language learning system is able to recognize 20 different Italian gestures (i.e., assistant or translating daily conversations between signers emblems).
