Aiming at automatic estimation of naturalness in timing control of non-native’s speech, we have analyzed the timing characteristics of non-native’s speech to correlate with corresponding subjective naturalness evaluation scores given by native speakers. In addition to word level statistical characteristics showing the differences between natives and nonnatives, we analyzed phone and syllable le...

Measuring the naturalness of images is important to generate realistic images or to detect unnatural regions in images. Additionally, a method to measure naturalness can be complementary to Convolutional Neural Network (CNN) based features, which are known to be insensitive to the naturalness of images. However, most probabilistic image models have insufficient capability of modeling the comple...

The article analyses the possibilities of developing an integrated indicator and a model of the assessment of forests naturalness using the data from the database of mountainous spruce forests situated in the Western Carpathians of Slovakia. The article presents two variants of such a model, one based on discriminant analysis, while the second one using an additive approach. The analysis of the...

PURPOSE Given the potential significance of speech naturalness to functional and social rehabilitation outcomes, the objective of this study was to examine the effect of listener perceptions of monopitch on speech naturalness and intelligibility in individuals with Parkinson's disease (PD). METHOD Two short utterances were extracted from monologue samples of 16 speakers with PD and 5 age-matc...

The computational view on image quality of Janssen and Blommaert states that the quality of an image is determined by the degree to which the image is both useful (discriminability) and natural (identifiability). This theory is tested by creating two manipulations. Firstly, multiplication of the chroma values of each pixel with a constant in the CIELab color space, i.e., chroma manipulation, is...

The objective of this article is to show that it is justified to assert that the existence of God is plausible, considering the fact that thinking itself is an immediate outcome (effect) of a thinker (cause). This idea may seem evident, but it is in fact challenged by certain claims of cognitive philosophers who aver that our knowledge of necessity and causation is, i...
