Narrative:
On departure the ATC controller advised us to go direct to tasie. We were already past zasro and direct to tasie and we believed the controller said kaise. We put direct to kaise in the FMS and executed. The controller questioned if we were going to tasie and we responded we were direct kaise. He then told us we had been directed to tasie but now to continue to kaise. Notified by controller of error and to continue to kaise. These two fixes are very similar sounding; especially over the radio. Change one of the names of these fixes. They are too similar sounding.
