Introducing the Database ExamStress for Speech under Stress
TL;DR: Experiments conducted using a newly created database of Czech speech under realistic stressed conditions show that the speech corpus can be used for development and evaluation of specific algorithms by identifying the extent of stress speakers have by analyzing their voices only.
Gender Distinction Using Short Segments of Speech Signal
TL;DR: Using vowel phonemes, an approach to automatic gender distinction in a short segment of normally spoken continuous speech achieves a gender identification accuracy of more than 90%.
Spectral Analysis of Speech under Stress
TL;DR: In this paper, a speech signal is used as a significant indicator of psychological stress when the speaker is involved in a stressful activity, based on specific changes in short-time spectrum of vowel phonemes.
