SpletTypically, adult females sustain phonation of "ah" from 15 to 25 seconds; while males range from 25 to 35 seconds. S/Z ratio: The patient is timed while sustaining production of "s" and "z" for as long as possible. "S" and "z" are essentially produced in the same way; however, the "z" is voiced, while the "s" is not.
