You can use V-Vocal that comes with Sonar 5 PE to achieve the same effects

TIP: Artificial Vocals Effect
Remember that Cher song called 'Believe' where you she had those strange-sounding vocals? Well, you can get the same effect with V-Vocal. Just set the Note parameter to 100, the Vibrato parameter to 0, and the Sense parameter to 100. Click the Correct button. Voila! Instant artificial vocals. Isn't technology fun?
7. V-Vocal can also automatically conform your audio to a musical scale. Click the Scale button to activate the Scale feature. Choose either Maj or Min option to choose a major or minor musical scale. Then click a key on the tiny keyboard display to choose the root note for the scale. If you want to define your own scale, you can click the notes to include (blue color), exclude (gray color), or bypass them (red color). Click the Correct button. To set the scale feature back to its default values, double-click the Maj or Min option.
TIP: Note Selection
Click the note names in the Pitch Correction Key (shown on the left of the Waveform display) to include, exclude, or bypass notes.
8. Close the V-Vocal window when you're finished.
