I'm trying to make one audio sound like the other, need help

Hello mates bday is coming up and she is a massive gaga fan, I am trying to make one file sound like the second one so it sounds like one normal file.
The sendspace attachment is the audio file i am trying to make sound like this one https://www.youtube.com/watch?v=n2Qp_pz1--4 . I think the sendspace file is autotuned, i dont really know. thanks

You will not be able to make the sendspace file sound exactly the same as the YouTube voice. The best you can expect is to make it fit a little better.
Am I right in thinking that the SendSpace file is the person’s name? If so, the first half needs to be 1 semitone higher than it is now and the second half needs to be 2 semitones lower than it is now. The whole thing needs to be slowed down, especially the last half. Try the “Sliding Time Scale / Pitch Shift” effect for making the pitch and speed changes.
First half, pitch +1 semitone, tempo about -15%
Second half, pitch -2 semitones, tempo about -65%

The last half also needs to fade out (“Fade Out” effect).

The tone of the voice is completely different. There is not a great deal you can do about that, but reducing the treble (Bass and Treble effect, Treble at -15) will make it a little better.

It still does not sound anything like the same voice, but it’s the thought that counts isn’t it?

omg thats really good! any chance it can be louder?

Select it Audacity Manual
and then apply the Amplify effect Audacity Manual
Note that playback must be stopped (not just paused) to apply effects.
