Sign Language is often the primary, or first, language for people with a significant hearing loss. It has a different grammar structure to standard English as well as a reduced vocabulary and hence can impact on the reading and writing of standard English for some users.
The main sign language used in India is Indian Sign Language (ISL), but there are several others in common use. When booking and using a signing interpreter, it is important to ensure that the person is appropriately qualified and operates at a good standard. Poor interpretation can impact on performance. Interpreters will need breaks during long meetings and often two are required to take over from each other.
Here is information on the new SignAble live sign language interpreter app and service which should greatly facilitate booking an interpreter that provide remote signing over video link.
