This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

A discussion of tonal categories relating to pitch perception discrimination thresholds focuses on the differences between pitch perception per se and the perception of tonal timing. In the light of several experimental studies on the perception of tonal timing categories in different languages, it is hypothesized that the perception of level tones can be related to the highly acute psychophysi...

Although pitch is a fundamental auditory percept that plays an important role in music, speech, and auditory scene analysis, the neural codes and mechanisms for pitch perception are still poorly understood. In a previous study (Cedolin and Delgutte 2005), we tested the effectiveness of two classic representations for the pitch of harmonic complex tones at the level of the auditory nerve (AN) in...

Some languages describe musical pitch in terms of spatial height; others in terms of thickness. Differences in pitch metaphors also shape adults’ nonlinguistic space-pitch representations. At the same time, 4-month-old infants have both types of space-pitch mappings available. This tension between prelinguistic space-pitch associations and their subsequent linguistic mediation raises questions ...

Experience-dependent enhancement of neural encoding of pitch in the auditory brainstem has been observed for only specific portions of native pitch contours exhibiting high rates of pitch acceleration, irrespective of speech or nonspeech contexts. This experiment allows us to determine whether this language-dependent advantage transfers to acceleration rates that extend beyond the pitch range o...

in the processing of carbon/carbon composites using polymer resin as the matrix precursor, it is inevitable that a porous structure was formed after carbonization. as a result, densification by liquid phase impregnation followed by recarbonization is required to obtain a densified composite. consequently, the char formability of resin is an important factor in reducing the number of densificati...

orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. in this study, a 3-d finite element analysis wa...

In a text-to-speech (TTS) conversion system based on the time-domain pitch-synchronous overlap-add (TD-PSOLA) method, accurate estimation of pitch periods and pitch marks is necessary for pitch modification to assure an optimal quality of the synthetic speech. In general, there are two major issues on pitch marking: pitch detection and location determination. In this paper, an adaptable filter,...

In this paper, we analyse the pitch trajectories of vocal imitations by non-poor singers. A group of 43 selected singers was asked to vocally imitate a set of stimuli. Five stimulus types were used: a constant pitch (stable), a constant pitch preceded by a pitch glide (head), a constant pitch followed by a pitch glide (tail), a pitch ramp and a pitch with vibrato; with parameters for main pitch...

In this paper, we investigate pitch contour modelling in speech synthesis based on segmental units. A convolutional pitch target approximation model is proposed. This model allows jointly stochastic modelling of framewise pitch and pitch contour of longer units, of which the intuitive relations are revealed by a convolutional target approximation filter. The pitch contour is stylized by a linea...
