Meeting Description:

The acoustics of turbulent sounds are difficult to model because the source is random noise rather than glottal oscillation and there are nonlinearities in the aerodynamic interactions between source and filter. In stops and affricates, these difficulties are obviously compounded by the inherently dynamic characteristics of the sounds. However, evidence is now mounting that sibilant fricatives also are dynamic, showing spectral changes over the course of the turbulence due not only to effects of palatalization or rounding from neighboring vowels and other segments, but also to the dynamics of the jaw rising from and lowering into neighboring vowels. Moreover, sibilant spectra can also be affected by the dynamics of the respiratory and laryngeal system in co-produced rising versus falling boundary pitch movements, as well as by conflicts in laryngeal features of the fricative and of adjacent sounds. In light of this evidence of variability across the purported steady-state interval, a fundamental question arises regarding sufficient ways of measuring, modeling and evaluating the dynamics of sibilants (and correspondingly other turbulent sounds as well). This question is further confounded by examination of contrastive turbulent sounds, and especially sibilants, in languages other than English, where commonly used measures in English (such as Centre of Gravity) have been shown to be inadequate for capturing contrasts. Furthermore, it remains unclear how these dynamic production patterns influence the perceptual representations of sounds in contrast. Studies using synthesis to examine dynamic perceptual cues tend to synthesize steady-state fricatives so that dynamic properties are focused in neighboring vowel formants, and we are very far from understanding what are critical acoustic cues contributing to the perception of categorical distinctions involving these sounds. In light of this question we are especially interested in perception of various sibilant systems by the same speaker, such as differences in perceiving sibilants in a second language where the inventory of contrasts and phonotactic dependencies differ from those of the sibilant system in the listener's first language. This workshop aims to bring together researchers who have been addressing these questions, in a forum where different approaches can be compared and evaluated against data from a wide range of languages.


Schedule of workshop: Two invited tutorial presentations will be followed by a dedicated poster session where audience members can interact in a more dynamic exchange with authors of submitted papers and then an extended discussion period.

Tutorial 1: Khalil Iskarous (University of Southern California, USA) on the articulatory dynamics of turbulent sounds and their mapping to acoustics.
Tutorial 2: Patrick Reidy (University of Wisconsin-Madison, USA) on the spectral kinematics of turbulent sounds using psychoacoustically-based spectral measures.

Poster session: We will accept up to 10 posters for presentation in a poster session that will be long enough for all posters to be viewed by all members of the audience.

Discussion: Interactive discussion among the tutorial presenters, the poster authors, and the audience, to be led by the workshop organizers.

Note: This schedule allows participants in this workshop to also attend the workshop on Speech dynamics, social meaning, and phonological categories to be held on the same day.

Organizers:
Marzena ┼╗ygis, Centre for General Linguistics (ZAS) & Humboldt University, Berlin, Germany
Mary E. Beckman, Ohio State University, Columbus, Ohio, USA

Call for Papers:

We solicit papers related to the dynamics and representation of turbulent sounds for presentation in a small poster session. Authors are welcome to submit more than one paper, but we ask that they be prioritized, in case we need to limit the number of accepted posters to fit into the allotted time.

Submit abstracts of not more than 2 pages, including references, as a pdf to:
turbulentsounds_labphonzas.gwz-berlin.de

Submission deadline: 30 April 2016
Notification of acceptance: 10 May 2016

Registration: There will be a registration fee (free for members of the Association for Laboratory Phonology; otherwise $15 for students, $30 for others) to cover the box lunch that will be provided to registered participants. Please register by 29 June 2016 at the link:
