The detection and modelling of emotions in speech remains a challenging issue in speech processing. The aim of the study presented here is to analyze and compare the use of several prosodic parameters in emotional speech in French. The data set used for the study contains utterances recorded in six emotional types: anger, fear, sadness, disgust, surprise and joy. The sentences of the emotional ...

Corpus based studies of spontaneous speech showed that filled pauses tended to precede relatively long and complex constituents. We examined whether listeners made use of such a tendency in speech processing. We tested the hypothesis that when listeners heard filled pauses they tended to expect a relatively long and complex phrase to follow. In the experiment participants listened to sentences ...

Naming and word-retrieval deficits, which are common characteristics of primary progressive aphasia (PPA), differentially affect production across word classes (e.g., nouns, verbs) in some patients. Individuals with the agrammatic variant (PPA-G) often show greater difficulty producing verbs whereas those with the semantic variant (PPA-S) show greater noun deficits and those with logopenic PPA ...

The males of six species of the Drosophila virilis group (including D. virilis) keep their wings extended while producing a train of sound pulses, where the pulses follow each other without any pause. The males of the remaining five species of the group produce only one sound pulse during each wing extension/vibration, which results in species-specific songs with long pauses (in D. littoralis a...

This study describes the tree-based modeling of prosodic phrasing, pause duration between phrases and segmental duration for Korean TTS systems. We collected 400 sentences from various genres and built a corresponding speech corpus uttered by a professional female announcer. The phonemic and prosodic boundaries were manually marked on the recorded speech, and morphological analysis, grapheme-to...

In the Drosophila virilis group the males of the virilis phylad species produce courtship song consisting of pulse trains with no pauses between successive sound pulses, whereas the males of the montana phylad species produce songs with clear pauses between the sound pulses. We obtained song data for F1 hybrids between D. virilis (representing the virilis phylad) or D. flavomontana (representin...

Prolonged sinus or atrial pause occurred in six patients with paroxysmal supraventricular tachycardia after drug administration. All six patients had normal sinus node function during control electrophysiologic study; the sinus cycle length ranged from 510 to 900 ms (mean 743 +/- 141) and the longest sinus node recovery time ranged from 800 to 1,230 ms (mean 1,018 +/- 168). A long sinus or atri...

Spike timing dependent plasticity (STDP) has been observed experimentally in vitro and is a widely studied neural algorithm for synaptic modification. While the functional role of STDP has been investigated extensively, the effect of rhythms on the precise timing of STDP has not been characterized as well. We use a simplified biophysical model of a cortical network that generates pyramidal inte...
