I use Soundforge. As AE says, The most important thing though is a good condenser microphone and a quiet room, as acoustically dead as possible. These day any PC audio software is good at recording. Once recorded you can use a lot of free VST software plug ins to enhance the voice, such as exciters, compressors and limiters. Hope that is of a little help.
