  The presence of a delay in a thermoelastic system destroys the well-posedness
and the stabilizing effect of the heat conduction. To avoid this problem we add
to the system, at the delayed equation, a Kelvin-Voigt damping. In this note we
point on the exponential stability of such system in order to improve the mean
result in our paper Well-posedness and exponential stability of a thermoelastic
system with internal delay (Applicable Analysis J 101, 4851-4865, 2022). We use
a frequency domain method in the proof of stability.
