The paper concerns prosody annotation especially for application in a corpus based speech synthesis. In order to establish the rules of automatic intonation modelling, phonetically labeled speech database of 4 hours has been perceptually and acoustically analyzed. The speech material included different text types and prosodically rich phrases. The(More)
Segmental duration was investigated in a database of Polish read speech (from one male speaker). The material was labeled automatically and then manually verified. The dependence of phone duration on a set of features was verified with the CART algorithm. The duration phenomena were analyzed in relation to syllable, foot and phrase structure. The results(More)
The paper provides an overview of the Polish Speech Database for taking dictation of legal texts, created for the purpose of LVCSR system for Polish. It presents background information about the design of the database and the requirements coming from its future uses. The applied method of the text corpora construction is presented as well as the database(More)
The material of this investigation comprised a group of 18 patients with deep hypoacousis (over 70 dB) or complete deafness which, depending on the onset of the deafness, was divided into the 3 categories: congenital, early childhood to 3rd year of life, and postlingual. All of them underwent ENT, phoniatric and stroboscopy examinations; in 10, X-ray(More)
This paper describes results of the investigation of Polish segmental duration for the purpose of speech synthesis. The experiment is a continuation of the previous work of the same authors [1] aiming at improving the outcome of the duration prediction mechanism to enhance the overall quality of synthesized speech. Duration prediction models for speech(More)
This paper presents the results of a set of experiments assessing the perceived quality of the Polish version of the BOSS unit selection synthesis system. The experiments aimed to evaluate the potential improvement of synthesis quality by three factors pertaining to corpus structure and coverage as well as levels of corpus annotation. The three factors(More)
Phoniatric and acoustic examinations were carried out in a group of 30 patients with dysphonia, including 15 with organic type and 15 with functional type. A complex phoniatric assessment offered the possibility to differentiate between these two groups of pathological voices. This was achieved also on the basis of acoustic analysis of the voice by(More)
