[Poster Presentation] Analysis of timbre changes caused by expressing fatigue speech
Takuro Shono, Masanori Morise (Yamanashi Univ.) SP2017-73
Abstract (in Japanese) (See Japanese page) 
(in English) To examine whether speech can be used as a biomarker for human fatigue,
we recorded both usual speech and speech by acting fatigue and analyzed them.
Five men and women uttered five short sentences including five Japanese vowels respectively.
Recorded speech was analyzed by using acoustic features related to timbre (spectral centroid, spectral tilt, aperiodicity at 3 kHz, the first and the second formant frequencies).
We compared these features in usual speech with that features in acted speech by calculating change ratio.
As a result of comparison, spectral centroid tends to decrease, and the aperiodicity tends to increase by acting fatigue.
