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 …

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

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