English nouns ending in an unvoiced f sound in the singular, but not spelled ff, change the f to a voiced v sound in the plural. Notice that the s of the plural is also voiced to a z in such words. There are other cases of this linguistic rule: the s in house is pronounced as a z in houses. See Verner's Law.
