Paralinguistic Microphone
The Human vocal tract is considered for its sonorous qualities in carrying prosodic information, which implicates vision in the perceptual processes of speech. These considerations are put in the context of previous work in NIME, forming background for the introduction of two sound installations; “Microphone”, which uses a camera and computer vision to translate mouth shapes to sounds, and “Mic...
متن کاملMicrophone Arrays
Such techniques—known collectively as beamforming—have been the subject of intense interest in recent years within the acoustic array processing research community. Unfortunately, such techniques have been largely ignored in the mainstream automatic speech recognition field, although this may rapidly change given the recent release and widespread popularity of the Microsoft Kinect R © platform....

متن کاملOne Microphone Source Separation
Source separation, or computational auditory scene analysis, attempts to extract individual acoustic objects from input which contains a mixture of sounds from different sources, altered by the acoustic environment. Unmixing algorithms such as ICA and its extensions recover sources by reweighting multiple observation sequences, and thus cannot operate when only a single observation signal is av...
متن کاملA Thermal Transducing Microphone
(6) If we now assign T0 to be the undisturbed air temperature of the surroundings, p as the small perturbation in pressure due to an acoustic wave and P0 as the ambient pressure we can derive the change in temperature occurring with a passing acoustic wave. ∆T is very small and is approximately ±0.23C with a very high sound level of 140 dB(SPL), ambient temperature of 20C, and an ambient pressu...
