Pitch detection of speech buried under white noise

Hi Everybody,
             Can anybody tell me about a pitch detection algorithm which
works in noisy environment.

Many Thanks in advance.

First, apply the lowpass filter with the cutoff at about 500Hz. Then, 
apply any common pitch detection algorithm such as normalized 
autocorrelation. For the further improvement, the tricks can be employed 
such as adaptive pitch tracking.

Perhaps, Mr. Dmitry Topez can give you a better advice on that. However, 
noisy signal is noisy signal - you should not expect the miraculous results.

i think it's "Terez" and also *Dr.* Dmitry Terez.  i did a google,
just to recheck name spelling, and came up with this interesting
little blurb from 4 years ago:
