What's the purpose of か in 自分に1年間頑張ったご褒美といいますか、プレゼントとして服をかいました。


Encountered in this video at around the 0:35 mark.

Full sentence: まだ11月で、クリスマスまで1ヶ月ほどありますが、自分に1年間頑張ったご褒美といいます **か**
、プレゼントとして服をかいました。

I understand the sentence as "It's still November and around a month to
christmas but I bought (myself) clothes as a present (so to say) as a reward
for my efforts during the year." (Correct me if I'm wrong)

But I don't understand why the question marker か is used here.
