Acoustic features of palilalia: A case study

Brain and Language, 2007
While a number of authors have suggested that patients with palilalia typically show a tendency to repeat words or phrases with an increasing rate, others maintain that an accelerating speech rate is not essential. The present paper reports the results of an instrumental analysis of the reiterations in a 60-year-old man with palilalia. Results indicate

Acoustic and facial features for speaker recognition

Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002
This paper gives an insight into biometrics used for speaker recognition. Three different biometrics are presented, based on: acoustic, geometric lip, and holistic facial features. Experiments are carried out using a corpus of the DAVID audio-visual database. Recognition accuracy is found to be similar in the 2 domains.

The acoustic features of vervet monkey grunts

The Journal of the Acoustical Society of America, 1984
East African vervet monkeys give short (125 ms), harsh-sounding grunts to each other in a variety of social situations: when approaching a dominant or subordinate member of their group, when moving into a new area of their range, or upon seeing another group.

A study of acoustic features for depression detection

2nd International Workshop on Biometrics and Forensics, 2014
Clinical depression can be considered as a soft biometric trait that can help to characterize an individual. This mood disorder can be involved in forensic psychological assessment, due to its relevance in different legal issues. The automatic detection of depressed speech has been object of research in the last years, resulting in different ...

Parkinson disease classification using one against all based data sampling with the acoustic features from the speech signals.

Medical Hypotheses, 2020
Parkinson's disease (PD) is a long-term degenerative disease that primarily affects the motor system of the central nervous system. This disease is difficult to diagnose and is one of the common diseases in the public.

Changes in Clinical Features of Acoustic Neuroma

Acta Oto-Laryngologica, 1991
During a 14-year period from 1976 to 1989, the authors experienced 160 cases of acoustic neuroma (AN). The clinical features were investigated in 132 of these cases (excluding those cases of recurrence and neurofibromatosis 2). The cases were divided into three periods for study.

Analysis of Acoustic Features for Speech Sound Based Classification of Asthmatic and Healthy Subjects

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
Non-speech sounds (cough, wheeze) are typically known to perform better than speech sounds for asthmatic and healthy subject classification. In this work, we use sustained phonations of speech sounds, namely, /α:/, /i:/, /u:/, /eI/, /o℧/, /s/, and /z ...

SOME EVIDENCE FOR ‘SPEECH’ AS AN ACOUSTIC FEATURE

British Journal of Psychology, 1976
Under conditions of serial recall of auditorily presented lists of digits, recall of the last item has been shown to be adversely affected by the presence of a redundant item following the list. This is known as ‘the suffix effect’ (Crowder & Morton, 1969). In a series of experiments it is shown that the size of this effect is not influenced by the

Acoustic features and acoustic change are represented by different central pathways

Hearing Research, 1995
The central processing of acoustic stimulus changes can be observed neurophysiologically in the mismatch negativity auditory evoked potential (MMN). Stimuli differing in interaural phase were used to investigate the contributions of the primary and non-primary auditory pathways to the encoding of binaural stimuli and to investigate passively elicited ...

Information theoretic acoustic feature selection for acoustic-to-articulatory inversion

Interspeech 2013, 2013
We use mutual information as the criterion to rank the Mel frequency cepstral coefficients (MFCCs) and their derivatives according to the information they provide about different articulatory features in acoustic-to-articulatory (AtoA) inversion. It is found that just a small subset of the coefficients encodes maximal information about articulatory ...
