Advertise at the beginning of the podcast. Nothing major just "Hey just want to let you know I have a stutter so if you hear me having trouble with any words that's what that is" You will be amazed at how much that helps, the mental relief alone is fantastic. You don't have to worry about trying to hide it or wonder what the audience will think of you Just that little sentence has got me through dates, job interviews, ect. Also what podcast is it? would love to give a listen later :)
