Prosodic Boundary Levels Conditioned by Syllable-final Vocalic Duration
نویسنده
چکیده
Prosodic structure encodes grouping of words into hierarchically layered prosodic constituents, including the prosodic word, intermediate phrase (ip) and intonational phrase (IP). This paper investigates the phonetic encoding of prosodic structure from a corpus of scripted broadcast news speech through analysis of the acoustic correlates of prosodic boundary at three levels of prosodic structure: Word, ip, and IP. Evidence for acoustic effects of prosodic boundary is shown in measures of vocalic duration local to the domain-final rhyme. These findings provide strong evidence for prosodic theory, showing acoustic correlates of a 3-way distinction in boundary level.

Effects of Prosodic Boudnaties on Segment Articulation in Standard Chinese
This study investigates the effect of prosodic boundary on the articulation and the acoustic properties of consonant and vowel segments, and vowel-to-vowel coarticulation across five prosodic boundaries in the Standard Chinese. The articulatory measures are obtained by electropalatography. The result shows that the domaininitial consonant /t/ is strengthened in a hierarchical fashion for prosod...

The goal of this paper is to investigate French word segmentation strategies using phonemic and lexical transcriptions as well as prosodic and part-of-speech annotations. Average fundamental frequency (f0) profiles and phoneme duration profiles are measured using 13 hours of broadcast news speech to study prosodic regularities of French words. Some influential factors are taken into considerati...
متن کاملWord segmentation in Persian continuous speech using F0 contour
Word segmentation in continuous speech is a complex cognitive process. Previous research on spoken word segmentation has revealed that in fixed-stress languages, listeners use acoustic cues to stress to de-segment speech into words. It has been further assumed that stress in non-final or non-initial position hinders the demarcative function of this prosodic factor. In Persian, stress is retract...

This paper describes the design and evaluation of prosodically-sensitive concatenative units for a Persian text-to-speech (TTS) synthesis system. Thesyllables used are prosodically conditioned in the sense that a single conventional syllable is stored as different versions taken directly from the different prosodic domains of the prosodically labeled, read sentences. The three levels of the Per...

This paper investigates the prosodic conditioning of the segment production and vowel-to-vowel coarticulation in the Standard Chinese through electropalatographic and acoustic analysis. The articulatory and acoustic measures were obtained for un-aspirated alveolar consonant /t/ and vowels /i/ and /a/. Results show that the domain-initial consonant is strengthened in a hierarchical manner in hig...
