  We discuss two-pion correlations as a possible experimental probe into
disoriented chiral condensates. In particular, we point out that the
iso-singlet squeezed states of the BCS type have peculiar two-particle
correlations in the back-to-back and the identical momentum configurations
which should be detectable experimentally. We motivate the examination of the
squeezed state by showing that such state naturally appears in a final stage of
nonequilibrium phase transitions via the parametric resonance mechanism
proposed by Mr\'owczy\'nski and M\"uller.
