Acoustic interactions for robot audition: A corpus of real auditory scenes

The Acoustic Interactions for Robot Audition corpus is introduced for research on sound source localization and separation, and for multi-user speech recognition. Its aim is to evaluate and train Robot Audition techniques, as well as Auditory Scene Analysis in general. It was recorded in six real-life environments with different noise presence and reverberation time, using two array configurations: an equilateral triangle, and a three-dimensional 16-microphone array set over a hollow plastic body. It includes clean speech data for static sources and tracking information for mobile sources. It is freely available at https://aira.iimas.unam.mx/.
