Why would a student need both interpreting and speech-to-text services for the same course?

Some deaf students may use both interpreting and speech-to-text services in the same class to better understand complex or technical content, such as medical, law school, advanced STEM, or foreign language courses. For example, they might read captions during a lecture and use an interpreter to follow class discussions. These supports are chosen based on the student’s needs, the course content, and how they communicate best.
