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)
The dependence of segmental duration on two sets of features was tested with the CART algorithm for a 2-hour speech corpus. The results were then compared to the results obtained previously for a limited database of 50 minutes with one of the feature sets. Both corpora contain recordings provided by the same male speaker, and both of them were annotated(More)
This study investigates cross-language differences in pitch range and variation in four languages from two language groups: English and German (Germanic) and Bulgarian and Polish (Slavic). The analysis is based on large multi-speaker corpora (48 speakers for Polish, 60 for each of the other three languages). Linear mixed models were computed that include(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)
This paper presents the stylization of intonation contours and clustering of F0 movements on accented and post-accented syllables based on annotated speech corpora. Special software – PitchLine – has been developed to enable the flexible quasiautomatic segmentation and parametrization of intonation curves. The experimental material obtained from a 15 min(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)
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)
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)
