I used 12xPentiumD 3.2GHz machines (4GB RAM) to train 5 hours of speech data, it took a day. 
So if you have similar computational resources, it may take 4 days.

Note that training 5 hours of speech data consumed about 3GB RAM, 
so training 20 hours of speech data may require 15GB (if you don't use any trick to reduce memory).
