How to compute phonetic posteriorgram in matlab?

I am working on project which requires phonetic posteriorgram to find similarity between two audio signals. I know that first I have to extract MFCC features, then train a Multi Layer Perceptron by giving input to this MLP and it will give you phonetic posterior probability for each phonetic class. I also read some papers but didn't find any algorithm. What is algorithm in matlab to train MLP and compute these posteriorgrams? I have also attached a example of posteriorgram of a phrase.
