  • 1 September 2010
One of the principal cues believed to be used by listeners to estimate the distance to a sound source is the ratio of energies along the direct and indirect paths to the receiver. In essence, thisExpand

Motion strategies for binaural localisation of speech sources in azimuth and distance by artificial listeners
Localisation in azimuth and distance of sound sources such as speech is an important ability for both human and artificial listeners. While progress has been made, particularly for azimuthExpand

Active hearing, active speaking
A static view of the world permeates most research in speech and hearing. In this idealised situation, sources don’t move and neither do listeners; the acoustic environment doesn’t change; andExpand
