Shadow Enchantment Spell ... emulating Enthrall

[Crai]

When Enthrall (2nd level Psychic spell) is emulated via the Shadow Enchantment spell, the Casting Time is reduced from 1 Round to 1 Standard Action.

Although look at the first 2 sentences of Enthrall's description text.

"If you have the attention of a group of creatures, you can use this spell to hold them enthralled. To cast the spell, you must speak or sing without interruption for 1 full round."

It's rare to see a spell's text mention anything about its Casting Time (because the Casting Time entry of the spell above the description does that for it). So it makes me wonder if there's a conflict here when Enthrall is emulated by Shadow Enchantment. Since I don't think Shadow Enchantment can nullify any description text entries of the spells it emulates.

Any thoughts on what is the actual Casting Time of this spell combo?

Yeah, after poking around a bit, I've not found any other spells that actually discuss or "reinforce" talk of the Casting Time within their respective Description text.

Just thought I'd throw that out there. :-)

Anybody? ....

I looked. I got nothing, from a rules perspective.

Casting time is 1 standard action. You have to talk for a full round.

Is there any situation in which this actually matters? It has a duration of "as long as you keep talking, up to one hour". Far as I can tell, if you cast Enthral, you have to stand there while you cast it. If you Shadow Enchant (Enthrall) you potentially gain the ability to Walk while you cast it.
