If you want to use Audacity to slow down the audio of your interviews, your
best choice is to use Effect > Change Tempo, which will slow the audio down
without changing the pitch so making it easier to understand than if you simply
changed the speed with Effect > Change Speed. Any effect will modify the
audio, so you would have to Edit > Undo the effect if you wanted to export the
audio files from Audacity at normal speed. If you use the Beta 1.3.3 version of
Audacity, this has a special variable speed slider with which you can adjust the
playback speed immediately without modifying the audio, although this does
alter the pitch as well as the speed.
