Tower controllers and a landing pilot reported another aircraft ignored instructions to cancel takeo...

Narrative:

Aircraft Y had landed Rwy14 and was rolling out to slow for parking. I then cleared aircraft X for takeoff Rwy14. I realized almost immediately that I should have just put him in position and not cleared him for takeoff. I then told aircraft X to cancel his takeoff and to line up and wait. At this point aircraft X still wasn't on the runway yet. He didn't respond. I then asked aircraft Y where he was parking; he told me; I told him to turn left next txy and to contact ground. Then I saw aircraft X starting to roll on the runway; I once again cancelled his takeoff clearance and told him to hold in position once again no response. I cancelled his takeoff 2 more times and never got a response. Aircraft Y in the meantime; had started to turn off the runway. Aircraft X departed and when I switched him to departure he responded. The pilot of aircraft X had done the same thing on ground control; when told to stand by for his read back; he disregarded the ground control instructions and started to read his clearance back anyways. I don't know if he was having radio issues or if he just has a habit of not listening to proper instructions. I feel that I probably used anticipated separation a little too early; but I did catch it in time. I don't know if a procedure change is necessary; but maybe the pilot of aircraft X; needs his radio fixed or needs more instruction on how to comply with ATC instructions.

Narrative: Aircraft Y had landed Rwy14 and was rolling out to slow for parking. I then cleared Aircraft X for takeoff Rwy14. I realized almost immediately that I should have just put him in position and not cleared him for takeoff. I then told Aircraft X to cancel his takeoff and to Line Up and Wait. At this point Aircraft X still wasn't on the Runway yet. He didn't respond. I then asked Aircraft Y where he was parking; he told me; I told him to turn left next TXY and to contact Ground. Then I saw Aircraft X starting to roll on the RWY; I once again cancelled his takeoff clearance and told him to hold in position once again no response. I cancelled his takeoff 2 more times and never got a response. Aircraft Y in the meantime; had started to turn off the runway. Aircraft X departed and when I switched him to departure he responded. The pilot of Aircraft X had done the same thing on Ground Control; when told to stand by for his read back; he disregarded the Ground Control instructions and started to read his clearance back anyways.
