  Though the cosmic censorship conjecture states that spacetime singularities
must be hidden from an asymptotic observer by an event horizon, naked
singularities can form as the end product of a gravitational collapse under
suitable initial conditions, so the question of how to observationally
distinguish such naked singularities from standard black hole spacetimes
becomes important. In the present paper, we try to address this question by
studying the ringdown profile of the Janis-Newman-Winicour (JNW) naked
singularity under axial gravitational perturbation. The JNW spacetime has a
surfacelike naked singularity that is sourced by a massless scalar field and
reduces to the Schwarzschild solution in absence of the scalar field. We show
that for low strength of the scalar field, the ringdown profile is dominated by
echoes which mellows down as the strength of the field increases to yield
characteristic quasinormal mode frequency of the JNW spacetime.
