American Sign Language Linguistics Overview

Principles

Definition

American sign language linguistics is a field of research that applies the principles, theories, and methodologies of general linguistics to the systematic study of American Sign Language. It investigates the structural properties of ASL, including its phonology (cherology), morphology, syntax, semantics, and pragmatics, as well as its acquisition, use, variation, history, and role within the Deaf community, thereby contributing to the understanding of this natural human language and broader linguistic theory.

Simultaneity and Nonmanual Grammar era

Alex Pentland [1] was active during this era at the Massachusetts Institute of Technology [3] and the University of Rochester [4]. Pentland [1]'s 1998 paper Real-time American sign language recognition using desk and wearable computer based video [6] introduced real-time ASL recognition through desk- and wearable-based video, enabling multimodal integration of manual and nonmanual cues and shaping subsequent research in sign-language processing during this era. Thad Starner [2] was active at Massachusetts Institute of Technology [3] and the Georgia Institute of Technology [5] during this era. Thad Starner [2]'s 1998 paper Real-time American sign language recognition using desk and wearable computer based video [6] demonstrated real-time recognition via desk- and wearable-based video, illustrating the era's emphasis on multimodal integration of manual and nonmanual cues and foreshadowing ubiquitous computing in sign-language research.

Multimodal Corpus and Computation era

William C. Stokoe [1], associated with Gallaudet University [3], stands as a foundational voice in this era of multimodal corpus and computation. His 2004 publication Sign Language Structure: An Outline of the Visual Communication Systems of the American Deaf [6] outlined the architecture of sign language and underscored the importance of structured, verifiable descriptions for computational annotation. Irit Meir [2] is associated with Stony Brook University [4] and Tel Aviv University [5] during this period. Her work, including The Paradox of Sign Language Morphology [7] (2005) and Patterned iconicity in sign language lexicons [8] (2013), advanced understanding of how morphology and iconic patterns organize sign language lexicons and provided important benchmarks for cross-linguistic typology and corpus-driven modeling.

Neural Translation and Recognition era

Hermann Ney [1] is featured alongside affiliations at the University of California, Los Angeles [3] and the University of Utah [4] during this era. In Neural Sign Language Translation [7], Ney introduced end-to-end neural translation for sign language, enabling direct mapping from sign input to textual output and driving the field toward scalable deep models in this era. Richard Bowden [2] is associated with the University of Freiburg [5] and Allegheny College [6] during this era. Bowden's key contributions in Neural Sign Language Translation [7] emphasize multimodal and cross-modal representations for ASL with deep learning, helping establish end-to-end frameworks that align visual gesture signals with linguistic output, a core driver in this era.
