Probing Acoustic Representations for Phonetic Properties [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020 Pre-trained acoustic representations such as wav2vec and DeCoAR have attained impressive word error rates (WER) for speech recognition benchmarks, particularly when labeled data is limited. But little is known about what phonetic properties these various

Influence of cross-section geometry and wire orientation on the phonon shifts in ultra-scaled Si nanowires [PDF]
, 2011 Engineering of the cross-section shape and size of ultra-scaled Si nanowires (SiNWs) provides an attractive way for tuning their structural properties. The acoustic and optical phonon shifts of the free-standing circular, hexagonal, square and triangular

Acoustic properties of dialysed kidney by scanning acoustic microscopy [PDF]
Nephrology Dialysis Transplantation, 1997 A correlation between acquired renal cysts in the dialysed kidney and renal cancer has long been debated, but no changes in the physical properties of kidneys at the microscopic level have been reported. The purpose of the present study was to classify the physical properties of the kidneys of patients undergoing haemodialysis at several stages of ...
