Importance of Different Temporal Modulations of Speech: A Tale of Two Perspectives
Samik Sadhu, Hynek Hermansky
How important are different temporal speech modulations for speech recognition? We answer this question from two complementary perspectives. Firstly, we quantify the amount of phon…

Complex Frequency Domain Linear Prediction: A Tool to Compute Modulation Spectrum of Speech
Samik Sadhu, Hynek Hermansky
Conventional Frequency Domain Linear Prediction (FDLP) technique models the squared Hilbert envelope of speech with varied degrees of approximation which can be sampled at the requ…
