Video of Obama spelling "RSPECT," he had no idea that he misspelled the word

The entire talk is available here.

(see 3:25 into the video for the misspelling)
I have seen news stories saying that Obama appears to have recognized his spelling mistake, but after reviewing these videos it is very clear that he had no idea that he had misspelled the word.

Fox News has the story available here:

In a throwback to the latter's infamous misspelling of the word "potato," Obama accidentally misspelled "respect" while introducing singer Aretha Franklin during a tribute to "Women of Soul" at the White House Thursday.  

“When Aretha first told us what … R-S-P-E-C-T meant to her,” Obama said, pausing briefly before the audience began laughing, apparently realizing his mistake. “She had no idea it would become a rallying cry for African Americans and women and anyone else who felt marginalized because of what they looked like, who they loved. They wanted some respect.” . . . .

Information on how CBS and NBC covered Obama's flub in their humorous lighthearted way is available here.  ABC News decided to ignore the story.
