In-Car McVAMPIRE – In-Car Multichannel Varying Mouth Position Impulse Response Dataset

This dataset contains impulse responses (IRs) that were recorded in a minivan with eight seats arranged in three seat rows. The IRs were captured with 14 distributed overhead microphones using a mouth simulator at eight passenger seat positions with eleven orientations each. In addition, the dataset contains IRs measured with six built-in car loudspeakers as well as driving noise recordings at various speeds.

This dataset supplements the Anechoic McVAMPIRE dataset which was captured with an identical microphone setup in an anechoic chamber. Both datasets can be used to simulate speech in a car from different seats with different speaker orientations including the loudspeaker-enclosure-microphone (LEM) system under anechoic or realistic, reverberant conditions.
