Opis:: The modern speech processing techniques enable new possibilities of potential applications. Besides speech and speaker recognition, also the information about speakers’ physical condition, emotional state or stress can be detected in speech signal. Since emotional stress can occur during deception, its detection in speech could be used for law or security services. The paper presents the comparative tests of two voice stress detection techniques: one based on trials of microtremors detection relying on an iterative EMD method (Empirical Mode Decomposition) and the second one based on the statistical analysis of fundamental frequency and MFCC parameters. The preliminary tests were carried on the group of 12 speakers (6 males and 6 females) answering yes/no to the list of a few dozen personal questions. The presented research revealed the speakers’ very high personal influence on the obtained results.

Tytuł:: Effect of sleepiness in the voice on speaker recognition performance

Opis:: The issue of the influence of speaker state on voice recognition has been analysed mainly in relation to forensics and biometric security systems. Sleepiness in the voice is a rather under-researched problem, and the few works in this area focus almost exclusively on the recognition of sleepiness rather than on its influence on the change of the speaker's voice characteristics. This paper discusses the issue of the influence of the speaker's state on voice recognition, describes the acquisition method of the acoustic database of voice drowsiness recordings used in the tests. It also discusses the subjective sleepiness scales used in the study and presents the results of the influence of sleepiness on the effectiveness of automatic speaker recognition based on a classical system using the Mel-Frequency Cepstral Coefficients parameterisation and the Gaussian Mixture Models classification.

Tytuł:: Recognition of speaker’s age group and gender for a large database of telephone-recorded voices
Autorzy:: Staroniewicz, Piotr
Powiązania:: https://bibliotekanauki.pl/articles/2202432.pdf
Data publikacji:: 2022

Opis:: The paper presents the results of the automatic recognition of age group and gender of speakers performed for the large SpeechDAT(E) acoustic database for the Polish language, containing recordings of 1000 speakers (486 males/514 females) aged 12 to 73, recorded in telephone conditions. Three age groups were recognised for each gender. Mel Frequency Cepstral Coefficients (MFCC) were used to describe the recognized signals parametrically. Among the classification methods tested in this study, the best results were obtained for the SVM (Support Vector Machines) method.

Opis:: Courts in Poland, as well as in most countries in the world, allow for the identification of a person on the basis of his/her voice using the so-called voice presentation method, i.e., the auditory method. This method is used in situations where there is no sound recording and the perpetrator of the criminal act was masked and the victim heard only his or her voice. However, psychologists, forensic acousticians, as well as researchers in the field of auditory perception and forensic science more broadly describe many cases in which such testimony resulted in misjudgement. This paper presents the results of an experiment designed to investigate, in a Polish language setting, the extent to which the passage of time impairs the correct identification of a person. The study showed that 31 days after the speaker’s voice was first heard, the correct identification for a female voice was 30% and for a male voice 40%.
