PRE-SCHOOLER QUESTIONS ENCOURAGING COGNITION
2018
When pre-schooler learns language, development of his cognitive processes changes, ability to classify and generalise rises. Child’s needs and interests encourage him to ask, answer, think, act. Word meanings are used and sought in various speech situations, especially when expressing all known, unknown, understood, not understood verbally. Asking and answering questions requires certain vocabulary, ability to formulate thoughts and find contact with communication partner in dialogue. Aim: study of the pre-schooler question content, influence thereof on formation of cognitive interests. Methods and materials: analysis of theoretical literature, observations, conversations with children, wri…
The effect of harmonic context on phoneme monitoring in vocal music
2001
The processing of a target chord depends on the previous musical context in which it has appeared. This harmonic priming effect occurs for fine syntactic-like changes in context and is observed irrespective of the extent of participants' musical expertise (Bigand & Pineau, Perception and Psychophysics, 59 (1997) 1098). The present study investigates how the harmonic context influences the processing of phonemes in vocal music. Eight-chord sequences were presented to participants. The four notes of each chord were played with synthetic phonemes and participants were required to quickly decide whether the last chord (the target) was sung on a syllable containing the phoneme /i/ or /u/. The mu…
Cantus: Construction and evaluation of a software solution for real-time vocal music training and musical intonation assessment
2016
The development of the ability to sing or play in tune is one of the most critical tasks in music training. In music education, melodic patterns are usually learned by imitative processes (modelling). Once modelled, pitch sounds are then associ-ated to a representation according to a syllabic system such as the Guidonian system - or an arbitrary single syllable - or western graphic notation system symbols. From a didactic standpoint, few advances have been made in this area besides the use of audio-supported guides and existing software, which use a microphone to analyse the input and estimate the pitch or fundamental frequency of the given tone. However, these programmes lack the necessary…
Effects of functional endoscopic sinus surgery on the acoustics of the sinonasal tract
2017
Background: Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and corresponding 3D casts. Methodology: Nasal and paranasal cavities of formalin-preserved cadavers and corresponding 3D replicas were excited by sine tone sweeps from an earphone placed in the epipharynx.The response was picked up by a microphone at the nostrils. Different FESS procedures were performed and the a…
A General Fuzzy-Parsing Scheme for Speech Recognition
1985
In this paper a Speech Recognition Methodology is proposed which is based on the general assumption of ‘fuzzyness’ of both speech-data and knowledge-sources. Besides this general principle, there are other fundamental assumptions which are also the bases of the proposed methodology: ‘Modularity’ in the knowledge organization, ‘Homogeneity’ in the representation of data and knowledge, ‘Passiveness’ of the ‘understanding flow’ (no backtraking or feedback), and ‘Parallelism’ in the recognition activity.
Restricted Decontamination for the Imbalanced Training Sample Problem
2003
The problem of imbalanced training data in supervised methods is currently receiving growing attention. Imbalanced data means that one class is much more represented than the others in the training sample. It has been observed that this situation, which arises in several practical domains, may produce an important deterioration of the classification accuracy, in particular with patterns belonging to the less represented classes. In the present paper, we report experimental results that point at the convenience of correctly downsizing the majority class while simultaneously increasing the size of the minority one in order to balance both classes. This is obtained by applying a modification o…
Evolución jurisprudencial de la protección ante el discurso del odio en España en la última década
2012
El discurso de odio es un problema que en los últimos años está adquiriendo un alta relevancia, tanto en el plano internacional, como en el nacional. El aumento de la utilización de la libertad de expresión con el objetivo de legitimar la provocación a la xenofobia, en particular, en contra de minorías sociales, es una actitud que está poniendo en peligro la cohesión social de las sociedades actuales. Es por esto que aquí se estudia la jurisprudencia que diversos órganos han dictado en España, con el objetivo de observar cuál ha sido su evolución durante la última década. ABSTRACT. Hate Speech is an increasing problem that, in the last decade, is acquiring a special relevance, at both the i…
Automated Characterization of Mouth Activity for Stress and Anxiety Assessment
2016
International audience; Non-verbal information portrayed by human facial expression, apart from emotional cues also encompasses information relevant to psychophysical status. Mouth activities in particular have been found to correlate with signs of several conditions; depressed people smile less, while those in fatigue yawn more. In this paper, we present a semi-automated, robust and efficient algorithm for extracting mouth activity from video recordings based on Eigen-features and template-matching. The algorithm was evaluated for mouth openings and mouth deformations, on a minimum specification dataset of 640x480 resolution and 15 fps. The extracted features were the signals of mouth expa…
A simple algorithm for finding short sigma-definite representatives
2010
We describe a new algorithm which for each braid returns a quasi-geodesic sigma-definite word representative, defined as a braid word in which the generator sigma_i with maximal index i appears either only positively or only negatively.
Asymptotic bit frequency in Fibonacci words
2021
It is known that binary words containing no $k$ consecutive 1s are enumerated by $k$-step Fibonacci numbers. In this note we discuss the expected value of a random bit in a random word of length $n$ having this property.
