Wav2Aug: A Drop-In Speech Augmentation Policy
Gianfranco Dumoulin Bertucci, Mirco Ravanelli
SpecAugment is the dominant speech augmentation policy, but researchers have studied it primarily for automatic speech recognition (ASR), and it operates on spectrograms, limiting…
Remarks on Redheffer's inequality
Nagi Suzuki, Shingo Takeuchi
Redheffer's inequality and its extensions are applied to study the behavior and estimates of the first eigenvalue of -Laplacian with respect to . Furthermore, a Redheffer-typ…
Properties of generalized Jacobi elliptic functions with three parameters
Hajime Sato, Nagi Suzuki, Shingo Takeuchi
Jacobi elliptic functions and complete elliptic integrals are generalized using three parameters. These generalized functions and integrals are closely related to ordinary differen…
Estimates for the first eigenvalue of the one-dimensional -Laplacian
Ryuji Kajikiya, Shingo Takeuchi
In the present paper, we study the first eigenvalue of the one-dimensional -Laplacian in the interval . We give an upper and lower estimate of and study it…
