Emotional Speech Corpora

Abstract

Emotion databases are divided into acted/non-acted, induced and naturalistic databases. Simulated databases are also called actor based databases for instance they are collected from experienced professional actors. The actors are given some sentences and they are asked to express these sentences in different emotions. These are called full blown emotions and ar more expressive than real ones. Induced data bases are also called Elicited data bases and are collected by creating an artificial emotional situation. in this case the speakers are made to involve in the conversational situation with the anchor. With out the knowledge of the speaker that they have been recording the data bases are more natural and realistic ones than the simulated ones. Natural emotions are some what difficult to record because collection of wide range of emotions naturally is difficult. Some of the instances of naturalistic emotions are collected from call center conversations, cockpit recordings during unnatural conditions, patient doctor conversations and so on.
