Yes: your ears... Seriously.. 'denoising' is as vague and blurry as 
'enhancing'. As people have already suggested there are many different 
approaches and consequently tools. Experiment a lot and see what gives 
the best result for what you need.
'Cleaning' aim is, in my humble opinion, #1 to consider: e.g. do you 
want to make the voice simply as intelligible as possible (in this case 
you don't care about possibly destroying its timbre with funky EQ) or do 
you want to maintain its character as much as possible (in this case you 
have very low room for extreem EQ..)?

Yes. There are many powerful tools, but first try and decide which 
routes you'd like to try (e.g. if you need a noise-gate, an eq, a 
(fft-based) denoiser, etc.)
