aweful squeel sound on audio prompts, please help

I use audio prompts for lap times, heart rate and pace.  Right before I get told the information, the garmin lets out this weird squeel/beep.  it's really annoying.  Can it be turned off so that I just get the information spoken to me without that squeely noise?

This is what it sounds like, regardless of what brand earphones I use.  from Apple Airpods to Microsoft surface Buds and so on.
