When any witness examined under sections 446.010 to 446.180 cannot clearly understand and speak the English language, his examination shall be made through a competent interpreter, duly sworn correctly to translate into his language to him all questions put to him, and his answers thereto, into the English language; and the officer taking his deposition shall reduce the questions and answers to writing, in the English language, which, being distinctly translated to him by said interpreter, shall be sworn to and subscribed by said witness.
