What is Yvonne Elliman singing?

Question

Listen to the five seconds between 1:09 to 1:14 in her classic disco song "If I Can't Have You". I have heard this part many times, but can't tell if she's actually singing something, or just making sounds to go along to the music. What do you think?

Answer 1

I think she's just singing the vocals without acually using words.

Answer 2

I like that song.
