Is this what you have in mind? Film yourself lip synching to Sam and Dave? And then having the video appear on your living room TV set every hour on the hour for the benefit of your dog???
That has no resemblance to my own imaginings, and I think that the words are superfluous. What I have in mind is something that changes each hour or shorter period to indicate the remaining time to wait. There are dogs who hear their owner's car a mile away - this would be like being able to hear it all the time.
Few dogs understand "minutes" but they do have a strong circadian rhythm, often seen when we go off of daylight saving time. If the owner has a regular schedule, just leaving for work, a dog can get used to that, but if absences are unpredictable, each instance can feel like abandonment in a trap. That happens often enough that it is always a worry where communication is weak and one-sided.
