This study investigates effects of spatial auditory cues on human listeners' response strategy
for identifying two alternately active talkers (“turn-taking” listening scenario). Previous …

This study introduces a Quality of Experience (QoE) model of loudspeaker-based spatial
speech reproduction, which specifies quality elements and quality features relevant to …
