- This paper will discuss the use of psychoacoustic evaluation as a tool for optimization of the soundscape simulator developed in the Listen project. The listen project is a three-year research project focused around developing a demonstrator, which auralizes the sound environment produced by road and railway traffic. The resolution of the parameter space of the simulator heavily influences the performance of the simulator. The perceptual resolution of the parameter space is investigated and the resolution is adjusted accordingly. The most important parameter is velocity. Adjustments of the resolution of this parameter alone gives a 60% reduction of the usage of memory.

- This project examines how the emotional content of a synthesised and robotic-sounding speech signal can be modified by manipulating high-level acoustic parameters using commonly available sound design digital tools. Stimuli were created on the basis of trends described by the literature and verified via our own analysis of emotional speech produced by actors. A listening test was run to verify whether the emotions expressed by the stimuli were discriminated by the listeners. Neutral and sad sentences were successfully identified. Happy sentences were identified with a lower degree of success, while angry sentences were, for the majority of cases, confused with happy. From the analysis of the test results and the stimuli we formulated hypotheses on why the identification of certain emotions was not successful and how this result could be improved in further work.
