Is it common to omit “about” when using the phrase **excited about** in spoken English?

Question

I assume these two sentences are grammatical and idiomatic.

"Maria’s starting to get pretty excited about the wedding."

"I'm excited about it."

It sounds like the speaker is saying

It was the first AI boom. People were really excited it.

So, is it common to omit "about" when using the phrase excited about in spoken English?

Answer 1

I hear "People were really excited. It was the AI boom ... "

The speaker is clearly fluent in English, but he is equally clearly not a native speaker, so his accent may be misleading you at times.
