Non-pilot - I just like to listen.  What does it mean when they say "delete speeds except for ?  (something that starts with a D)" ?

Can you give a reference to an exact time in a particular archive file, or maybe post a small snippet of the phrase you are asking about?

It means to that there is a restriction on a given procedure to cross a certain fix/waypoint at a given speed. The call to "delete speed restriction at xxx " or "cancel speed restriction at xxx" means to disregard the speed restriction at that particular fix.

A good example would be to look at either the SUNST3, KEPEC3, or TYSSN3 arrivals into KLAS. They have both crossing and speed restrictions listed for given fixes. ATC could tell the pilot to delete the speed restrictions at any point there, should they need to.

I'm listening to KDFW and they are again saying 'delete speeds except for deets'  except I don't know what they mean so I'm probably misunderstanding the word I'm calling 'deets'.  That's just what it sounds like to me.  The controller says it and the pilot repeats it and it still sounds like deleting speeds except for deets.

Looks like it's actually spelled DIETZ. You'll find it about 11nm SE of the airport on the IFR Low charts. I also found it on the Cedar Creek Seven Arrival and it showed the speed at DIETZ should be 210 knots.

Is 'delete' standard phraseology though? Wouldn't 'disregard' be more appropriate? I think I've heard 'disregard speed restrictions' a couple of times, but that was perhaps different circumstances?

Yes. The same verb is used in the 7110.65 and other FAA documents. For example, see the "NOTE" in section 5-7-4 (emphasis mine):
Quote from: 7110.65 5-7-4
An instruction to “resume normal speed” does not delete speed restrictions that are applicable to published procedures of upcoming segments of flight, unless specifically stated by ATC.

Likewise, see page two of this InFO document (emphasis mine):

Quote
DELETE SPEED RESTRICTION
Cancels published speed restrictions.

"Delete the speeds" is standard and different than "resume normal speed." The first deletes all the speeds on an arrival or departure procedure. The second cancels a previously issued ATC speed restriction, but does not give relief on any future speed restrictions on a procedure.  In this case the pilot would have to comply with any upcoming speed restrictions.

I hear some controllers who imply that "resume normal speed" deletes speed restrictions, but that is technically not correct.
