I opened up EBA in "DS SDAT Extractor" to see if I could find any unused songs, Instead I found unused voice acting.

It seems that the Rhombulan leader was to have a voice during the opening to it's first stage.
Also the Chief(not Agent Chieftain) has a voice clip I don't recognize.

The Rhombulan's lines were split into multiple files, So I put them together into one file, [Which you can get here].
If you want the separate files, [Look here].

And [here is the Chief's voice clip]. It's him saying "Yes" in a slightly hammy way. Not overly exciting, But it does have a slight echo.

I've also found a bunch of unused voice clips in Spider-Man: Shattered Dimensions for the DS.
Mainly, Stephen Hawking, (possibly)Ultimate Spidey and References to Electro.
If anyone is interested, I can post them too.

edit: Or maybe no one can be interested at all in this.
*shrugs* Oh well.
