In expressive piano performance, the performer emphasises a melody by increasing its intensity and by anticipating it by some tens of milliseconds (melody lead). In this contribution, we continue previous research on the influence of asynchrony and intensity variation on the perceived salience of a particular tone or voice with three experiments. In Experiment I, threetone piano chords are pres...

Measuring the affective state of an individual across species with comparable non-invasive methods is a current challenge in animal communication research. This study aims to explore to which extent affect intensity is conveyed in the vocal behaviours of three nonhuman primate species (Campbell's monkeys, De Brazza's monkeys, red-capped mangabeys), which vary in body size, ecological niche and ...

The purpose of this work is to evaluate and to compare the acoustic properties of oesophageal voice and voice prosthesis speech production. A group of 14 Italian laryngectomized patients were considered: 7 with oesophageal voice and 7 with tracheoesophageal voice (with phonatory valve). For each patient the spectrogram obtained with the phonation of vowel /a/ (frequency intensity, jitter, shimm...

For quantifying vocal load over extended periods of time in real-life situations, the best adapted tools are voice dosimeters or voice accumulators. Such devices measure the frequency (F0), the intensity (SPL) and the duration of speech occurrences, generally using an accelerometer attached to the base of the neck. Growing attention has been focused on evaluating patterns of vocal behavior beca...

This paper provides a review of our earlier work on the realisation of stress and word accents in Swedish which serves as a pame for introducing voice source parameters in prosodic analysis. Duration and Fo measures have been related to continuously scaled estimates of perceivedprominence. Intensity variations appear to be less distinctive and are largely influenced by the overall breathgroup p...

PURPOSE The primary purpose was to demonstrate the feasibility of executing treatment tasks focused on increasing loudness in a group format for individuals with Parkinson's disease (PD). A second purpose was to report preliminary pre-to-post treatment outcomes for individuals with PD immediately after they complete the group program. METHODS The group intervention is described. Fifteen adult...

In this paper we provide an extensive analysis of voice service in wireless IP networks. Voice traffic is serviced with priority over the rest of the traffic. Hence, we concentrate on the voice traffic in the analysis. We model the packetized voice traffic with Markov Modulated Poisson Process (MMPP), and we propose an analytical framework for its analysis in wireless networks. Also, we created...

Acoustic differences between the vowels in filled pauses and ordinary lexical items such as nouns and verbs were examined to know if there was systematic difference of voice-quality. Statistical test of material taken from the Corpus of Spontaneous Japanese showed that, in most cases, there was significant difference of acoustic features like F0, F1, F2, intensity, jitter, shimmer, TL, H1-H2, H...
