  We investigate the early-time accelerated universe after the Big Bang. We pay
attention to the dissipative properties of the inflationary universe in the
presence of a soft type singularity, making use of the parameters of the
generalized equation of state of the fluid. Flat Friedmann-Robertson-Walker
metric is being used. We consider cosmological models leading to the so-called
type IV singular inflation. Our obtained theoretical results are compared with
observational data from the Planck satellite. The theoretical predictions for
the spectral index turn out to be in agreement with the data, while for the
scalar-to tensor ratio there are minor deviations.
