In a database of emotional speech, dimensional descriptions of emotional states have been correlated with acoustic variables. Many stable correlations have been found. The predictions made by linear regression widely agree with the literature. The numerical form of the description and the choice of acoustic variables studied are particularly well suited for future implementation in a speech synthesis system, possibly allowing for the expression of gradual emotional states.
