Need to use Sonar for voice only - little use for music

I was thinking of buying Sonar X1 Studio.

As I searched the Internet, and YouTube videos, I'm guessing the program does cool stuff... for music, but I'm only interested in what the software can do for the spoken voice.

I've been using

-AVS4YOU Audio,
-Magix Music Editor 3, and yesterday downloaded
-Audacity 1.3 Beta.

Between all three, I have enjoyed taking the speaking voices and manipulated them somewhat to my... satisfaction?

I would like to do more to edit voices, but need to know if the cost for Sonar X1 is worth it for whatever voice tweaking features it should have that is better than the features the above programs offer.

Too, as I understand it, one or both of the other Sonar X1 versions, offer an audio editor that - I think - offers some audio features that the software I now use do not. The question here is pretty much the same: In order to get the "other" audio features, is the extra cost worth the software, of which, I would pretty much be only using for tweaking voices?

For the curious, I'm attempting to collect voices for characters in a novel I'm co-writing. The voices would be found on the story's website, and in any book trailers we make.


Thanks for any help.

And if you're considering spending that much money for an audio editor you should at least take a look at Adobe Audition before writing that check.

One of Audition's features that you might find useful is the ability to split an audio clip into several different frequency bands so you can process them separately. It also has a nice noise reduction feature. Cakewalk software and Adobe Audition complement each other very well. If you had the bucks I'd recommend getting both of them.
