I have working on emotional state recognition. I need to know that a emotional state how much time is stable. I need to a creditable reference for hypothesis in my work.
A point in A-V space is a emotional state that recognize from paralingustic information. Change a emotional state is move from that point to other point in this space more than a threshold!
I want to know how much minimum time for stability of emotional state in speech?
