This paper will focus on studying the effects of external electric field, hydrostatic pressure, impurity position, as well as the geometrical size on the electromagnetically induced transparency of a spherical Gaussian quantum dot. To this end, we discuss absorption coefficient, refractive index, and the group velocity of the probe light pulse under the influence of the above-mentioned agents. Our results reveal that the electromagnetically induced transparency occurs in the system and the geometrical size of the spherical Gaussian quantum dot system, confinement potential, hydrostatic pressure, and impurity position impact strongly on its frequency, transparency window, and group velocity of the probe field. Obtained results indicate that compared to the atomic system, one can control electromagnetically induced transparency and the group velocity of light through the confinement potential, external agents, and geometrical size of the dot.
