By examining acoustic marks of Czech stress, this paper attempts to provide an answer to the question of whether or not perceived accents in the Czech language have an objective existence. A neural network is used to predict the position of accents without lexical information. Three parameters (intonation, duration and intensity) are considered(More)
The present paper examines three methods of intonational stylization in the Czech language: a sequence of pitch accents, a sequence of boundary tones, and a sequence of contours. The efficiency of these methods was compared by means of a neural network which predicted the f0 curve from each of the three types of input, with subsequent perceptual assessment.(More)
The present paper provides an acoustic description of macrointensity patterns of stress units (prosodic words) in read Czech, as reflected by the intensity of syllable nuclei. Normalized intensity values show that there is a gradual macrodynamic decrease over the inter-pause group, followed typically by a significant intensity reset. Local intensity drops(More)
We describe an experiment based on introspective assessment of inter-syllabic prosodic changes in two different conditions (global – continuous sentences, and local – two-syllable portions of speech), by means of discrete targets (Higher, Same and Lower). The results show that global evaluation is very problematic for the listeners and that f 0 is the best(More)
