ANALYSIS OF VOICED SPEECH EXCITATION DUE TO ALCOHOL INTOXICATION

Milan Sigmund, Petr Zelinka
2011 Information Technology and Control  
Experimental results show that analysis of glottal excitation appears to be a useful approach to provide evidence of alcohol intoxication of over 1‰.  ...  For use in our experiments, a new collection of Czech alcoholized speech consisting of phonetically identical speech data spoken in both sober and intoxicated state was created.  ...  These changes include both the content of speech and its acoustic form expressed physically by parameters of speech signal.  ...

Statistical Analysis Of Glottal Pulses In Speech Under Psychological Stress

Zdenek Brabec, Ales Prokes, Milan Sigmund
2008 Zenodo  
Publication in the conference proceedings of EUSIPCO, Lausanne, Switzerland, 2008  ...  Such a speech cue would allow an analysis without the physical presence of the speaker. In this paper, we focus on actual effects of stress on speech signal.  ...  The broad sense reflects the underlying long-term stress and the narrow sense refers to the short-term excitation of the mind that prompts people to act.  ...

Influence of Speaker-Specific Parameters on Speech Separation Systems

David Ditter, Timo Gerkmann
2019 Interspeech 2019  
Furthermore we conclude that current systems separate (short-term) speaking styles rather than (long-term) speaker characteristics.  ...  Our analysis allows us to do performance predictions for given speakers based on measurements of their fundamental frequency.  ...  To detect the voiced speech frames and formants we again use Praat [14, 15] where the formant analysis is based on a short-term Linear Predictive Coding (LPC) analysis [17] .  ...

Speaker Discrimination Using Long-Term Spectrum of Speech

Milan Sigmund
2019 Information Technology and Control  
In this article, we investigate a specific long-term speech spectrum with respect to its use for speaker recognition.  ...  The long-term effect was satisfied by averaging short-term autocorrelation coefficients over the whole utterance.  ...  For research, infrastructure of the SIX Center was used.  ...

Accommodating sample size effect on similarity measures in speaker clustering

Alexander Haubold, John R. Kender
2008 2008 IEEE International Conference on Multimedia and Expo  
Speaker data is represented as Mel Frequency Cepstral Coefficient (MFCC) vectors, and features are compared using the KL2 metric to form clusters of speech segments for each speaker.  ...  We investigate the symmetric Kullback-Leibler (KL2) distance in speaker clustering and its unreported effects for differently-sized feature matrices.  ...  In the domain of lecture videos some work is available for discussion scene analysis [4] . Speaker clustering is based on the comparison of features extracted from a speaker segmented audio stream.  ...

Voice Pleasantness of Female Voices and the Assessment of Physical Characteristics [chapter]

Vivien Zuta
2009 Lecture Notes in Computer Science  
This study completes the collected voice parameters, which count so far as indicators of physical attributes and as factors for voice attractiveness.  ...  It has been demonstrated that there seem to be non-linguistic patterns from which listeners refer to the appearance of a speaker.  ...  For instance the statistical analyses for Acoustic Parameters and Speakers' Characteristics are currently carried out and of course other examinations about the physical parameters that lead listeners  ...

Shoou-Yih D. Lee, Deborah E. Bender, Rafael E. Ruiz, Young Ik Cho
2006 Health Services Research  
The study was intended to develop and validate a health literacy test, termed the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA), for the Spanish-speaking population.  ...  The design of SAHLSA was based on the Rapid Estimate of Adult Literacy in Medicine (REALM), known as the most easily administered tool for assessing health literacy in English.  ...  Thus, the relative fit of the two models and the parameters would be estimated using the MULTILOG program, suitable for dichotomous and polytomous item analysis (Thissen 1991) .  ...
