Non-linguistic sound refers to the vocalisations made by a person which are not phoneme based, but still convey valuable meaning. Sneezing, coughing, snorting, passing wind, even laughter. Such sounds, or the neural signals that would trigger them. must be processed by any speech recognition system, if it is to achieve a full range of interaction, within a virtual environment.

The talk is primarily focussed on demonstrating his new invention 'hypersonic sound'. It is essentially a way to precisely focus sound, or as the inventor puts it "put sound where you want to." This has obvious implications for 3D sound effects in virtual reality and channeled sound cones in augmented reality.
The story of Daniel Kish, a man whose senses are out of balance; a man who sees with sound.
It might well be that current experiments with binaural sound for VR 3D recreation of sounds based on the relative positions of the ears, and the head shape of the listener, are not quite getting the full picture of sound reception. It seems facial skin also has a part to play.
Unlike the mapping of the sense of smell, which has odourant maps all over the olfactory bulb in no particular order, the sense of sound is remarkably well ordered. Synapses line up in an overlapping orchestra, with multiple redundancies, a study has found.
The value of sound is ofter overlooked when designing a virtual world, who, for all the prolieration of speaker systems, all too often concentrate on visual only - especially the non gameworlds.
Nails on a blackboard. It is an unbearable noise, one that sends shivers through anyone who hears it. But why does it do this, and more importantly, how can a virtual environment replicate the effect in any sound?
We finally understand enough about the way sound signals are processed into electrical signals, to go one better than the cochlea implant. We can tap directly into the auditory nerve itself.
All manner of approaches are being fielded these days to try and create a workable haptic interface, that allows the true feeling of touch to an object that is only virtually there. One of the more esoteric, is the use of sound to shape the pressure fields in the air. Specifically, the use of ultrasound.
Usually when we think of sensory input channels - sight, sound, touch, taste, smell, balance - we think of the traditional hierarchical order, under the brain. It seems that that hierarchy is not as cut and dried as we once thought, with interesting implications for virtual worlds.

Soon computers may be able to generate eerily accurate sounds for film soundtracks. For the first time, a team of computer scientists has reproduced the sound of flowing and dripping by modelling the way water creates sound in the physical ...
Thanks to researchers at the Centre for Digital Music (C4DM) at Queen Mary, University of London, anyone watching the World Cup on their computer can now filter out the droning sounds of vuvuzela playing in South Africa's stadiums.
Is sound only sound if someone hears it? Apparently not. Silent videos that merely imply sound - such as of someone playing a musical instrument - still get processed by auditory regions of the brain.

It has been found that infrared light can stimulate neurons in the inner ear as precisely as sound waves, a discovery that could lead to better cochlear implants for the deaf, and possibly quieter VR interfaces for sound.
