It is rarely necessary to slow down when speaking through an interpreter. Under usual
circumstances, an interpreter can keep up with a normal rate of speaking. The only exception
to be aware of is when long passages are read aloud, since people tend to read much faster
than they speak conversationally. If you (or a student) plans to read aloud, it would be
helpful if you make sure to indicate the page number of the passages being read so that the
deaf student can follow along in the book.
