Matched ltering and adaptive beamforming are both necessary for e cient speech dereverberation and noise reduction by microphone arrays. This can be achieved by the identi cation of impulse responses. In this contribution, we show that adaptive microphone arrays are sensitive to identi cation errors of impulse responses, particularly due to speaker movements. We prove that adjusted matchedlteri...

An acoustic energy density probe is a sensor that uses multiple pressure transducers to measure acoustic energy density. Calibrating each pressure transducer an acoustic energy density probe at the same time is a difficult problem because the pressure transducers have a unique location and orientation. Two main issues arise that are involved in simultaneous calibration. The first issue is a uni...

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...
