Analysis of Speech under Stress Based on Short-Time Spectrum of Vowel Phonemes
Original language description
This paper deals with speech signal spoken by speaker under stress. The investigation of speaker's stress is based on specific changes in short-time spectrum of vowel phonemes. For each selected signal segment, the spectrum was computed by means of two different approaches: Fourier transform and chirp transform. Comparative results between both spectra served for speaker's stress identification. In case of speech under stress, the obtained spectra differ towards the higher frequencies due to enhanced pitch modulation.
