The scenario of constant-roll inflation is studied where the DBI scalar field plays the roll of inflaton. Since, the second slow-roll parameter is assumed as a constant in the scenario which could be of order of one, some modified terms appear in the perturbations parameters that will be determined. Then. in a comparison with the last observational data, the free parameters of the model are obtained in which only for these values the model comes to a consistency with observational data.
