The Presence and Behaviour of Birds at Two Prescribed Fires in Sweden

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Shifting fire regimes pose immediate threats to animal conservation. Swedish birds appear to mostly ignore prescribed fire, and some species even continue to sing. Behavioural plasticity towards fire is poorly understood, but may prove to be an essential tool in animal conservation.

Articulation During Voice Disguise: A Pilot Study

Lecture Notes in Computer Science, 2021
Speakers can conceal their identity by deliberately changing their speech characteristics, or disguising their voices. During voice disguise, speakers alter their normal movements of the articulators, such as tongue positions, according to a predetermined strategy. Even though technology for accurate articulatory measurements has existed for years, few

Voice disguise and automatic speaker recognition

Forensic Science International, 2008
In this paper a newly developed Forensic Automatic Speaker Recognition System (FASRS) was introduced and the effect of 10 types of voice disguises that are common in forensic casework on the performance of this system was studied. In this study 10 types of disguised voices and normal voices from 20 male college students were used as test samples.

Formant manipulations in voice disguise by mimicry

2016 4th International Conference on Biometrics and Forensics (IWBF), 2016
The human voice can be disguised in many ways. The purpose of disguise could either be to impersonate another person, or to conceal the identity of the original speaker, or both. On the other hand, the goal of any biometric analysis on disguised voices could also be twofold: either to find out if the originator of the disguised voice is a given speaker,

FASR: Effect of voice disguise

2016 International Conference on Emerging Technological Trends (ICETT), 2016
Speaker recognition systems based on spectral features perform well in acoustically matched and noise-free conditions. Spectral features are unsuccessful to model information about the speaker at higher levels. Prosody which represents intonation, rhythm and stress of speech, better represents speaker characteristics at higher levels. Voice disguise is

Glottal fry and voice disguise: a case study in forensic phonetics

Journal of Biomedical Engineering, 1993
In recent legal proceedings, forensic phoneticians were called upon to analyse a tape-recorded message intended for the blackmail of a bank manager following the kidnap of his wife. The brief was to establish the likelihood that the tape recording may have been made by any one of three suspects, samples of whose speech were also made available.

Voice Disguise and Automatic Detection: Review and Perspectives

Lecture Notes in Computer Science, 2007
This study focuses on the question of voice disguise and its detection. Voice disguise is considered as a deliberate action of the speaker who wants to falsify or to conceal his identity; the problem of voice alteration caused by channel distortion is not presented in this work.

Detecting the presence of vocal disguise in the male voice

Journal of the Acoustical Society of America, 1981
This research examined the ability of naive and sophisticated listeners to detect extemporaneous disguise in the male voice. The experimental stimuli were sentences uttered in an undisguised and in a freely disguised fashion. The listeners were asked to decide whether a sentence was disguised or undisguised and to rate his/her degree of confidence in ...

Blind Detection of Electronic Voice Transformation with Natural Disguise

Lecture Notes in Computer Science, 2013
Electronic voice transformation with natural disguise ability is a common operation to change a person's voice and conceal his or her identity, which can easily cheat human ears and automatic speaker recognition(ASR) systems and thus presents threaten to security. Till now, few efforts have been reported on detection of electronic transformation, which

The effect of voice disguise on Automatic Speaker Recognition

2010 3rd International Congress on Image and Signal Processing, 2010
In this paper the effect of 10 kinds of disguise voices on the performance of a Forensic Automatic Speaker Recognition System (FASRS) was studied. 10 types of disguised voices and normal voices from 20 male college students were used as test samples.
