Audible
CD's are stored as raw audio data. Thats why you can fit about 80 minutes, it works out to be about 800 megabytes. MP3's can compress raw data down considerably. It does that by cliping off the parts of the sound wave that we don't really pay attention to. Thats why its known as a losey compression scheam. Spoken word doesn't need the fidelity that music does, so it can be highly compressed and a user doesn't mind it as much. I hope this helps.
