Signal Processing and Emotion Recognition I have to write a paper on emotion recognition.
More specifically on how different parameters affect the algorithms effectiveness. I have already read a lot about this and done research using OPENSmlie, (extracting mostly MFCCs) and WEKAs clasificators to get the best results. I use EMO DB.

However what i need is more theoretical knowledge, and information about already published papers on that subject. Especially newer ones, say from the last couple of years. I want to know, how peaople approach this problem, and how good their latest results are.

I was wondering if maybe there were some experts on that here.
Could you recommend any good recources / links to such papers. Or an effective way of finding the latest ones?
For the latest improvements read the papers from the latest speech conferences, for example here are two tracks on Emotions in latest ICASSP:

Emotion recognition I

Emotion recognition II
