A sign language interpreter facilitates communication between the deaf or hard-of-hearing community and hearing individuals by translating spoken language into sign language and vice-versa in real-time, working in diverse settings like schools, hospitals, and events. 

Key responsibilities include analyzing spoken messages, reflecting tone and emotion, maintaining confidentiality, and adhering to professional ethics. Interpreters need strong fluency in both languages, often requires certification, and engage in ongoing skill development and vocabulary building
