Narrative:

Cleared for SWANN1 departure. Received clearance over ACARS. Did not realize it was the SWANN1. Thought it was radar vectors to fix (first). Missed turn at 3 mi to 150 degree heading. Turned when told to. No evasive action required. Pre departure clearance is somewhat repetitive day in and day out, happened because when you get clearance over ACARS the need to hear it is gone.
