This paper proposes a sound localization algorithm inspired by a cross-channel algorithm first studied by MacDonald et. al in 2008. The original algorithm assumes that the Head Related Transfer Functions (HRTFs) of the robotic head under study are precisely known, which is rarely the case in practice. Following the idea that any head is more or less spherical, the above assumption is relaxed by using...
Sound source localization is an important feature designed and implemented on robots and intelligent systems. Like other artificial audition tasks, it is constrained to multiple problems, notably sound reflections and noises. This paper presents a sound source azimuth estimation approach in reverberant environments. It exploits binaural signals in a humanoid robotic context. Interaural Time and Level...
