problems with registering

I have a windows 7 32 bit pc with audacity 2.0.2 and i have a problem with the registering. When i register i can’t hear my voice in the headset, i tried to modify the settings in audacity but. Between the input and the output the difference is too big. The voice arrives too late in the headset

I presume that you mean “monitoring”? Listening to what you are recording while you are recording?
Not all hardware is able to do that. What sort of headphones and microphone are you using? How are they connected to your computer?

You need to turn off “Software Playthrough” in the Transport menu - that is probably where the delayed echo is coming from.
