I went through and checked all of Chantal Strand's Voice acting for the young kids on imdb base.
She did voice Stacie in Barbie and The Diamond Castle. And another bonus is she looks a lot like most of the characters she does voice.
She voiced Sofia in Barbie as The Island Princess.
She voiced Lacey in Barbie in The Twelve Dancing Princesses (this brings my point to why Kelly is being the one acted by Stacey because Stacey has always had worried moments whereas Chelsi dislikes changes, and the aspect of change unless she chooses it.)
She voiced Rose in Barbie and the Magic of Pegasus.

In case you were confused about who Rose actually was amongst the misnamed Cloud Princesses just because the Cloud Queen is the Cloud Queen it doesn't make the three younger girls' Princesses they might just be her selected apprentices, honestly, Princess Rose below.
She voiced Kelly in Barbie of Swan Lake.
She voiced Kelly in Barbie as Rapunzel
And She voiced Kelly in Barbie in The Nutcracker.
(Kelly still has bangs showing here.)
That's a lot same voice credits for the same character over and over again multiple times.
But she did not, yep she did not voice Kelly from within Barbie in A Christmas Carol Kelly below.
And this actually makes sense because Barbie isn't portraying or playing the protagonist of the story she is telling either physically. Eden Starling is actually not played by Barbie at all contrary to popular belief. Eden Starling is actually voiced by Morwenna Banks when it comes to her dialogue and Eden's singing voice is taken over by Melissa Lyons (Who is Barbie's singing voice.) She has participated in most of the movies where Barbie has to sing for the characters that look like Barbie Eden however is not one of them. Eden has green eyes, Barbie has always had blue eyes.
How Kelly Sheridan's voice credits are labeled on inmd in the list below.
