Is the goal to accomplish the task or to learn how DSP works and
accomplishes that task?

If you just want to remove voice and you don't care how it's done,
then I recommend you use Audacity, not Octave:

If you need to learn how DSP can be done in order to remove vocals,
perhaps other list members can help you accomplish this.
