Sign Language Recognition
Sign Language Recognition (shortened generally as SLR) is a computational task that involves recognizing actions from sign languages. This is an essential problem to solve especially in the digital world to bridge the communication gap that is faced by people with hearing impairments. Solving the problem usually requires not only annotated color (RGB) data, but various other modalities like depth, sensory information, etc. are also useful. Isolated sign language recognition ISLR (also known as word-level SLR) is the task of recognizing individual signs or tokens called glosses from a given segment of signing video clip. This is commonly seen as a classification problem when recognizing from isolated videos, but requires other things like video segmentation to be handled when used for real-time applications. Continuous sign language recognition In CSLR (also known as sign language transcription), given a sign language sequence, the task is to predict all the signs (or glosses) i ...

Sign Languages
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutually intelligible, although there are also similarities among different sign languages. Linguists consider both spoken and signed communication to be types of natural language, meaning that both emerged through an abstract, protracted aging process and evolved over time without meticulous planning. Sign language should not be confused with body language, a type of nonverbal communication. Wherever communities of deaf people exist, sign languages have developed as useful means of communication and form the core of local Deaf cultures. Although signing is used primarily by the deaf and hard of hearing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spoken Language
A spoken language is a language produced by articulate sounds or (depending on one's definition) manual gestures, as opposed to a written language. An oral language or vocal language is a language produced with the vocal tract in contrast with a sign language, which is produced with the body and hands. Definition The term "spoken language" is sometimes used to mean only oral languages, especially by linguists, excluding sign languages and making the terms 'spoken', 'oral', 'vocal language' synonymous. Others refer to sign language as "spoken", especially in contrast to written transcriptions of signs. Context In spoken language, much of a speaker's meaning is determined by the context. That contrasts with written language in which more of the meaning is provided directly by the text. In spoken language, the truth of a proposition is determined by common-sense reference to experience, but in written language, a greater emphasis is placed on logical and coherent argument.
