Research project Voice Directivity

The project investigates the physical properties of dynamic voice directivity and determines perceptual thresholds for the temporal resolution. Thereby, the project distinguishes between scenarios with 3DoF (3 Degrees of Freedom) and 6DoF (6 Degrees of Freedom) since significantly different thresholds are expected to be found between both scenarios. Investigating these interconnected, scientifically relevant questions serves to gain knowledge about the properties of human voice directivity and its perceptual significance. Furthermore, the investigations allow determining relevant features for the auralization of dynamic voice directivity in virtual acoustic environments. The application-related findings are especially relevant for future implementations of human speakers in virtual acoustic environments since human voice directivity with high temporal resolution goes along with a high effort, both for the measurements and the auralization. Thus, systematically investigating the trade-off between appropriate temporal resolution and the required effort is highly relevant.
