Bug after stopping / restarting Rhasspy in the terminal

I noticed that every time I stop Rhasspy with a CTRL + C in the terminal window and then restart it
the sounds are produced several times which corresponds to Rhasspy’s relaunch multiple!
example $ {RHASSPY_BASE_DIR} /etc/wav/beep_error.wav

How to prevent this without doing a reboot?

Thank you
