EVALUATION OF A SYNTHETIC SPEECH SYSTEM WHICH SIMULATES VOCAL EMOTION BY RULE
IR MURRAY, J.L. Arnott · 2024
The aeveropment a! a system which can add vocal emotion effects by rule to synthetic speech is described.Perception experiments conducted to evaluate the realism of the simulated emotions are also described.The results of these experiments have indicated that the emotions are generally recognised by naive listeners, and that the different emotions have different levels of recognition.The system simulates six discrete emotions (anger, happiness.sadness, tear, disgust and grief) and operates on a microcomputer with a commera ai high quality speech synthesiser.7719 emotion is selected by name, and the appropriate effects are generated by nrle and form an integral pan of the speech cutout; input text is unrestricted Expansion of the system to include a threeoimensr onal model of emotions, allowing a wide range of emotions of dilferent strengths to be simulated.is described.The proposed use of the system as part of a communication prosthesis for the non-vocal is described, and other applications ol synthetic speech with emotion are discussed.
