GUIDE DES APPLICATIONS
Sign-language translation research maps signed-language video into another language's text or speech representation.

Signed languages have their own grammar and include manual and non-manual information, so this is a language task rather than a universal gesture-to-word lookup.
ASL and other signed languages are natural languages, distinct from simply gesturing the words of a spoken language. Handshape, movement, position, and non-manual features such as facial and body movements can carry linguistic information. Continuous signing includes transitions and coarticulation, so boundaries are not always explicit pauses. Research pipelines may use RGB video or extracted pose keypoints and may train recognition and translation components jointly. A gloss is a textual label for a sign used in annotation; a gloss sequence is not automatically a grammatical spoken-language translation. Camgoz and colleagues' 2018 work introduced PHOENIX-2014T using German Sign Language weather broadcasts and German text. Its language and domain do not establish performance for every signed language or everyday situation. Data coverage and community involvement matter for evaluation.
Evaluating a research model on a defined sign-language video and text dataset.
Comparing hand, face, and body information in a multi-articulatory translation model.
Using sequence-level gloss annotations as an intermediate representation in a research pipeline.
Working with Deaf participants and language experts to define useful tasks and evaluation criteria.
Research explores broader data coverage, different representations, and translation quality. Deaf communities and language experts help define the needs, cultural context, and evaluation of these tools. A narrow research demonstration should not be treated as a reliable replacement for an interpreter in every setting, and language-specific results require appropriately scoped assessment.

Signed languages such as ASL have distinct grammar and use spatial and non-manual information, so translation is a language task.
Les haussements de sourcils, l'inclinaison de la tête et la forme de la bouche peuvent transformer une déclaration en question ou en modifier le sens. L'IA doit donc suivre le visage, pas seulement les mains.
Keypoints are a visual representation for later processing, not an automatic translation or privacy guarantee.
Sequence modeling handles the relationship between visual observations and linguistic units over time.
The interdisciplinary perspective emphasizes relevant participants and expertise in defining and evaluating tools.
