The Core Situation
- Sign language is a full-fledged language
- Sign language is needed to communicate with deaf people
- The demand for translations into sign language is very high
Why not just use written text? Deaf people can read, can’t they?
Deaf people are often limited in their ability to comprehend written language. This is because human speech is based on phonemes and written language is an abstraction of spoken language. Therefore, people who have never heard spoken language tend to have difficulty in accessing written language.
As a result, many deaf people find it impossible to read and understand a written text.
Although subtitles may be helpful for some – such as those who become hearing impaired later in life – subtitles are not a suitable alternative for many sign language users.
