An image voice play apparatus for playing an AVI file includes: a control portion that when an instruction for a time search is issued, estimates the "number of voice chunks in one movi chunk," determines in which AVI chunk a voice chunk for the time search is situated, reads an idx1 I chunk in the "determined AVI chunk" without reading an idx1 chunk in an AVI chunk other than the ``determined chunk," and determines a play start position that corresponds to the time search.
