Macroscopic analysis of a corpus of emotional Standard Southern British speech signals has been performed to measure any changes in average fundamental frequency, speech rate, energy and first formant frequency. Seven acted emotional states were recorded and analysed for one male and one female speaker. Differences between neutral and emotional speech were found which agree with changes others have mentioned in the literature. Only the emotion sadness was found to be consistently and obviously different from neutral, while high activity emotions (such as elation and hot anger) could be distinguished from sadness. Additional measures are being developed which will further discriminate the emotions from one another. Results obtained to date are being evaluated for use in a speech synthesiser system.
