Use of Machine Learning for Deception Detection From Spectral and Cepstral Features of Speech Signals

open access: yesIEEE Access, 2021
In this research, four unique nonlinear speech features are extracted and analyzed to study the dissimilarity pattern between when the speaker is being deceitful and truthful based on how human speech is perceived.

Simulating Heat Stress of Coal Gangue Spontaneous Combustion on Vegetation Using Alfalfa Leaf Water Content Spectral Features as Indicators

open access: yesRemote Sensing, 2021
Vegetation heat-stress assessment in the reclamation areas of coal gangue dumps is of great significance in controlling spontaneous combustion; through a temperature gradient experiment, we collected leaf spectra and water content data on alfalfa.

A Spectral Condition for Feature Learning

open access: yesCoRR, 2023
The push to train ever larger neural networks has motivated the study of initialization and training at large network width. A key challenge is to scale training so that a network's internal representations evolve nontrivially at all widths, a process known as feature learning.

Estimation of the Underlying F0 Range of a Speaker from the Spectral Features of a Brief Speech Input

open access: yesApplied Sciences, 2022
From a very brief speech, human listeners can estimate the pitch range of the speaker and normalize pitch perception. Spectral features which inherently involve both articulatory and phonatory characteristics were speculated to play roles in this process,
