Seung-Eun Kim & Dr. Sam Tilsen publish new paper on how phonetic measures covary with speech rate

PhD candidate Seung-Eun Kim and Dr. Sam Tilsen published a paper in the July 2022 edition of the Journal of Phonetics.  The paper, titled  "An investigation of functional relations between speech rate and phonetic variables", characterizes how phonetic measures covary with speech rate. 

Abstract:

It is well known that speech rate is correlated with many phonetic variables. The current study aims to obtain a more precise characterization of how phonetic measures covary with speech rate.

Specifically, we assess whether there is evidence for linear and/or non-linear relations with rate, and how those relations may differ between phrase boundaries.

Productions of English non-restrictive (NRRCs) and restrictive relative clauses (RRCs) were collected using a method in which variation in speech rate is cued by the speed of motion of a visual stimulus. Articulatory and acoustic variables associated with phrase boundaries were analyzed; for each variable, Bayesian regression was used to obtain posterior parameter distributions for a set of generalized linear models.

Analyses of posterior predictions showed that:

  • Phonetic variables associated with a phrase boundary that follows the relative clause (post-RC boundary) were more susceptible to rate variation than those at a boundary that precedes the relative clause (pre-RC boundary).

 

  • Phonetic variables at the post-RC boundary also showed evidence for non-linear relations with rate, which suggest floor or ceiling attenuation effects at extreme rates.

 

  • On the other hand, substantial differences between syntactic contexts were found primarily at the pre-RC boundary.

 

  • A high degree of participant-specificity was observed in F0-related variables.
