Optimal head related transfer function spatial configurations designed to maximize speech intelligibility in multi-talker speech displays by spatially separating competing speech channels combined with a method of normalizing the relative levels of the different talkers in a multi-talker speech display that improves overall performance even in conventional multi-talker spatial configurations.
A computationally efficient method and device for adding spatial audio capabilities to new and existing centrally switched communication systems without modifying the internal operation of the systems or the switching architecture by producing a digitally filtered copy of each input signal to represent a contralateral-ear signal with each desired talker location and treating each of a listener's ears as separate end users.
