SPEAR Challenge

SPeech Enhancement for Augmented Reality

Welcome to the SPeech Enhancement for Augmented Reality (SPEAR) challenge website.

SPEAR logo

The SPEAR challenge offers the opportunity for researchers to benchmark existing speech enhancement algorithms and try out new ideas in the context of head-worn microphone arrays where positional information is available to the algorithm. Using recorded and simulated data, participants have to obtain the best estimate of a binaural target signal from a given microphone array where real time information of the wearer head rotation and of the target direction of arrival is available. Enhanced signals will be evaluated through metric calculation and crowdsourced listening tests. To help get started a baseline algorithm is provided.
