The aim of the study was to investigate influence of color hue saturation on emotional state of human. We use frontal EEG asymmetry to determine subject's emotional state. Our emotional stimuli summon opposite dynamics of frontal EEG asymmetry. Negative stimuli elicits decreasing of the value of frontal EEG asymmetry and positive stimuli increases the value(More)
219 At present time, the first formant of a vowel is established as the main characteristic of its phonetic type in speech [1, 2]. At the same time, the " formant key " that plays an important role in the speech of adults cannot be applied to the speech signals with high fundamental frequencies, such as vowels in the speech of children or singing vowels.(More)
207 The problem of the invariance of the perception of vowels remains unresolved despite numerous studies [1]. The same vowels produced by different people mainn tain their phonetic properties but considerable vary in acoustic parameters. At the same time, not only adults, but also little children can categorize vowels irrespective of the gender, age, and(More)
The effect of color hue saturation on the emotional state (ES) of humans has been investigated. Frontal EEG asymmetry was used to determine the subject’s ES. The emotionogenic stimuli caused converse dynamics of frontal EEG asymmetry. Negative stimuli elicited a decrease in the value of frontal EEG asymmetry, and positive stimuli increased the value of(More)
It is well known that for adult speakers positions of the formants are different for various vowels and they can often be predicted for each phoneme, so first two formant frequencies provide the classic acoustic description of adults vowels' quality. But spectral characteristics of the vowels produced by human voice vary over wide range. In particular this(More)
To study the continuity in speech development, an investigation of vowel-like sounds recorded in the course of longitudinal research of speech formation was carried out in 12 infants beginning with the first month up to 12 months of their life. It was revealed that features ensuring separation of vowel-like sounds are specific by their amplitude relation(More)
