How to slowdown playback in iTunes?

I have an audio book in iTunes (v10.2.2), the audio book is in over 300 MP3 segments. All is fine except the person who is reading the book is talking extremely fast, the person's voice has a hint of a "Chipmunks" sound so I'm thinking the audio was sped up. Is it possible to choose a setting in iTunes that will slow down the audio, such as on an iPhone you're able to choose 1x 2x and 1/2x speeds?

Thanks!,
Wesley
