###### Continuous sign corpora {-}
contain parallel sequences of signs and spoken language.
Available continuous sign corpora are extremely limited, containing 4-6 orders of magnitude fewer sentence pairs than similar corpora for spoken language machine translation [@arivazhagan2019massively].
Moreover, while automatic speech recognition (ASR) datasets contain up to 50,000 hours of recordings [@pratap2020mls], the most extensive continuous sign language corpus contains only 1,150 hours, and only 50 of them are publicly available [@dataset:hanke-etal-2020-extending].
These datasets are usually synthesized [@dataset:databases2007volumes;@dataset:Crasborn2008TheCN;@dataset:ko2019neural;@dataset:hanke-etal-2020-extending] or recorded in studio conditions [@dataset:forster2014extensions;@cihan2018neural], which does not account for noise in real-life conditions. Moreover, some contain signed interpretations of spoken language rather than naturally-produced signs, which may not accurately represent native signing since translation is now a part of the discourse event.

    Most of these data are from four native signers of ASL.

    This dataset includes 1,866 distinct canonical signs (i.e., grouping together very slight variants in production). The total number of sign tokens is 11,854.

    Restricting consideration to signs other than gestures and classifiers, there are 1,278 distinct canonical signs, and a total of 10,719 tokens.

    1,002 of the utterances in this collection are part of short spontaneous narratives (19). The remaining 885 utterances were elicited to illustrate a variety of constructions and sentence types.
