Looping Alarm Sound and Stopping with an Interrupt

Is it possible to loop an alarm sound indefinitely, with the option to say the wake word and tell it to stop - similar to how it works with Alexa?

I created a timer with Rhasspy and Home Assistant, but I don’t know if there’s a great way to play a notification sound for when the time is complete (i.e. an alarm sound). Similarly, I’d like to make an alarm clock where I can tell Rhasspy to set an alarm for a certain time, and when it’s that time an alarm would play.
