Abstract  This study investigates the role of temporal alignment, f0 and peak shape in de-termining perceived tonal target values in Neapolitan italian. In this variety, the alignment of the accent peak appears to be a strong perceptual cue to the question/statement identification (D‘Imperio and House, 1997), everything else being equal. In the present study, the f0 contour of a question, uttered by a female speaker of Neapolitan Italian, was stylized and resynthesized by means of PSOLA. A set of stimuli was created in which either tonal alignment was varied, while f0 height was kept constant, or f0 height was varied orthogonally to alignment. For the alignment manipulation, an additional variable was the shape of the accent peak, which could be either flat (creating a short plateau) or sharp. Thirty Neapolitan subjects listened to the stimuli and identified each as a question or a statement. The results suggest that the contribution of f0 peak height to the question/statement identification is much less important than that of target alignment. More-over, peak shape affects the perceived alignment of the target tone, in that flat peak stimuli cause the perceived target to be displaced towards the end of the plateau.


FOCAL ACCENTUATION AND BOUNDARY PERCEPTION

Abstract  In this paper, an experiment concerning focal accent distribution and phrase boundary perception in South Swedish is discussed. In previous studies on prosodic phrasing in Standard Swedish, no reliable, simple relation between focal accent distribution and boundary perception has been found. However, results from the present perception experiment show that focal accent distribution has an effect on the perceived composition of an utterance in South Swedish. Since the South Swedish focal accent is characterized by a fall (not by a rise as in Standard Swedish), the focal accent gesture can be perceived as a combined focal accent gesture and boundary signal.


CONTINUOUS LINGUISTIC TONETIC REPRESENTATION USING POLYNOMIAL RESIDUALS

Abstract  Normalised F0 data from the two accent types of Kagoshima Japanese are used to argue for 1) a continuous (polynomial) rather than a discrete—mean representation, and 2) the superiority of parameters derived from polynomial residuals over standard deviation measurements in the modeling of tone. It is claimed that both are preferable for linguistic-phonetics and speech technology.


THE EXPONENTIAL NATURE OF F0 TARGET TONE INTERPOLATION

Abstract  The intonational phenomena of Kagoshima Japanese (KJ) will be investigated in this paper. More precisely, this paper has two aims. Ishihara (1998, 2000) reports that KJ’s accentual oppositions: Type A and Type B, show a different F0 realisation range at word level. First of all, l will show that this difference between Type A and Type B appearing at word level is also maintained at phrase level. Secondly, I will show that KJ’s HLLLLL(L) sequences—which are represented by the interpolation from a high to a low tone in Autosegmental—Metrical (AM) model (i.e. Pierrehumbert and Beckman, 1988)—exhibit exponential F0 curves, by acoustical-phonetically describing the sequences in question.

Abstract  It has been claimed that morpho-syntactically equivalent declarative and propositive sentence types are not distinguishable intonationally in Korean. This paper investigates whether this is so, by analysing, within in the Autosegmental-Metrical model, short declarative and propositive sentences, produced by 4 native Seoul Korean speakers. It is shown that the two types are in fact distinguishable by a combination of boundary tones, the duration of the sentence-final syllable, and accentual phrasing.
