We investigate the contribution that lingual gesture delay makes to lenition of postvocalic /r/. This study uses a socially-stratified, audio-ultrasound corpus of Scottish English containing recordings from two sociolects; one with postvocalic /r/ weakening and the other with strengthening. We quantify auditory strength of rhoticity and the timing of the anterior lingual gesture relative to the...

This study investigated how coda voicing contrast in English would be phonetically encoded in the temporal vs. spectral dimension of the preceding vowel (in vowel duration vs. F1/F2) by Korean L2 speakers of English, and how their L2 phonetic encoding pattern would be compared to that of native English speakers. Crucially, these questions were explored by taking into account the phonetics-proso...

In many sports, players are often required to accelerate immediately after rapid changes of direction (CODs) before performing a subsequent COD movement. Therefore, court-based players will often not attain their maximum velocity before having to decelerate and change direction. The purpose of this study was to determine what kinematic factors affected fast and slow straight acceleration (SA) a...

Prosody serves an important function in speech communication: prosodic phrasing groups words into pragmatically and semantically coherent smaller chunks and prosodic prominence encodes the discourse-level status and rhythmic structure of a word within a phrase. Acoustic cues to prosody are available from the speech signal and can be used by listeners to recover the pragmatic and discourse meani...

We use a 3-D finite difference numerical model to generate synthetic seismograms from a simple fractured reservoir containing evenly-spaced, discrete, vertical fracture zones. The fracture zones are represented using a single column of anisotropic grid points. In our experiments, we vary the spacing of the fracture zones from 10-meters to 100-meters, corresponding to fracture density values fro...
