The first video I saw concerning this: Huberman Smeared.
I realize how slow I talk. I'd speed this up 1.25 or 1.5 if I could- I'll see about importing this into some audio editor, I have to look it up. 
Just thought I'd address this as I what this sounds like to listen to, but strangely, and I record and mentally prod myself to speak faster, it sounds faster to me as I speak, than when I listen.
I sound stupid and/or drunk, and I'm neither. 
Also, I knew this but forgot it- it can be speeded up on Buzzsprout, right at the bottom of the Episode frame, hover and a button 1x appears. For those that are as slow as me. 
Thank you for reading.
