W sound in "heroic"

[WilliamTaft]

Here are the audio pronunciations from the Britannica Dictionary and the Longman Contemporary.

The Britannica IPA is /hɪˈrowɪk/; and the Longman is /hɪˈrəʊɪk $ -ˈroʊ-/.

I am not sure if I heard the W sounds in the two versions. Are they there?

 

[Tarheel]

Believe it or not, that's a normal pronunciation.

 

[5jj]

The /w/ glides are there, but we do not normally transcribe them.
