Far-Field Automatic Speech Recognition [PDF]

Proceedings of the IEEE, 2020
The machine recognition of speech spoken at a distance from the microphones, known as far-field automatic speech recognition (ASR), has received a significant increase in attention in science and industry, which caused or was caused by an equally ...

Far-Field Speaker Recognition

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
In this paper we study robust speaker recognition in far-field microphone situations such as meeting scenarios. By applying reverberation compensation and feature warping we achieved significant improvements under mismatched training-testing conditions. To capture useful information from multiple distant microphones, two approaches for multiple channel

Blackbody far-field coherence

Journal of the Optical Society of America A, 2020
We revisit the spectral coherence properties of far-field radiation emanating from an aperture in a blackbody cavity on the basis of Kirchhoff’s boundary conditions. We point out that the far zone cross-spectral density matrix derived earlier in the literature by separately propagating all three aperture-field components does not show transversality of
