Non-parametric techniques for pitch-scale and time-scale modification of speech

E Moulines, J Laroche - Speech communication, 1995 - Elsevier
Time-scale and, to a lesser extent, pitch-scale modifications of speech and audio signals are
the subject of major theoretical and practical interest. Applications are numerous, including …

SPWVD-CNN for automated detection of schizophrenia patients using EEG signals

SK Khare, V Bajaj, UR Acharya - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
Schizophrenia (SZ) is a psychiatric disorder characterized by cognitive dysfunctions,
hallucinations, and delusions, which may lead to lifetime disability. Detection and diagnosis …

Signal estimation from modified short-time Fourier transform

D Griffin, J Lim - IEEE Transactions on acoustics, speech, and …, 1984 - ieeexplore.ieee.org
In this paper, we present an algorithm to estimate a signal from its modified short-time
Fourier transform (STFT). This algorithm is computationally simple and is obtained by …

[LIBRO][B] Time-frequency analysis

L Cohen - 1995 - abarproject.ir
Changing frequencies is one of the most primitive sensations since we are sur-rounded by
light of changing color, by sounds of varying pitch, and by many other phenomena whose …

Characterization of arbitrary femtosecond pulses using frequency-resolved optical gating

DJ Kane, R Trebino - IEEE Journal of Quantum Electronics, 1993 - ieeexplore.ieee.org
The frequency-resolved optical gating (FROG) technique for characterizing and displaying
arbitrary femtosecond pulses is presented. The method is simple, general, broadband, and …

The importance of phase in speech enhancement

K Paliwal, K Wójcicki, B Shannon - speech communication, 2011 - Elsevier
Typical speech enhancement methods, based on the short-time Fourier analysis-
modification-synthesis (AMS) framework, modify only the magnitude spectrum and keep the …

Using phase retrieval to measure the intensity and phase of ultrashort pulses: frequency-resolved optical gating

R Trebino, DJ Kane - JOSA A, 1993 - opg.optica.org
We recently introduced a new technique, frequency-resolved optical gating (FROG), for
directly determining the full intensity I (t) and phase φ (t) of a single femtosecond pulse. By …

Single-shot measurement of the intensity and phase of an arbitrary ultrashort pulse by using frequency-resolved optical gating

DJ Kane, R Trebino - Optics letters, 1993 - opg.optica.org
We introduce a new technique, frequency-resolved optical gating, for measuring the
intensity I (t) and the phase?(t) of an individual arbitrary ultrashort pulse. Using an …

Improved phase vocoder time-scale modification of audio

J Laroche, M Dolson - IEEE Transactions on Speech and …, 1999 - ieeexplore.ieee.org
The phase vocoder is a well established tool for time scaling and pitch shifting speech and
audio signals via modification of their short-time Fourier transforms (STFTs). In contrast to …
