The interplay of lip and tongue movements in variable /t d/ productions in American English
Karolina Broś
University of Warsaw, Poland
American English is well-known for optional /t d/ deletion in clusters, as in best [bes] man, kept [khep] going or whipped [wɪp] butter (Coetzee 2004, Tagliamonte & Temple, 2005, Walker 2012). However, different studies have led to varying conclusions concerning the conditioning of the process and its categoricity. Research shows that even in the absence of an acoustic trace of /t d/, articulatory gestures related to the alveolar constriction are still there (Browman & Goldstein 1990; Purse & Turk 2019), although they may be of a smaller magnitude, which questions the completeness of deletion from a phonological standpoint. The disadvantage of previous articulatory studies is that they only elicit a small number of tokens in a few speakers and do not necessarily take other important factors into account.
In this talk, I present a study designed to remedy these obstacles and look at /t d/ trapped in between bilabial consonants vs a neutral context (stopped making, stopped eating) to look at the interplay of acoustics with articulation. Importantly, motion capture combined with ultrasound is used. This allowed for eliciting a larger data sample and using a cheaper, less time-consuming way of articulatory data extraction.
A total of 46 American English speakers were recorded while producing 320 target sentences each. Based on audiovisual recordings, lip aperture and lip compression measurements are now being compared with the acoustic output (following Broś & Krause 2024) and confronted with tongue gestures during the production of key sound sequences. Importantly, at least three different options are present in the data: a fully pronounced /t d/, a weakened /t d/ and a fully deleted /t d/.
The study is the first to look at the interplay between acoustics and articulation in pronounced vs. unpronounced /t d/ segments using a combination of the two instrumental techniques. It also uncovers additional factors related to articulatory control during speech that are due to the differences between two speaker populations: monolinguals and bilinguals (heritage Spanish speakers).

About CRL Talks
We look forward to seeing you at Friday at 11 a.m. in CSB 280 or via Zoom. The Zoom link for each talk will be provided in the CRL Talks announcement email. If you are not subscribed to CRL Talks announcements, just sign up to our new Google Group!.
If you still do not want to subscribe to the CRL Talks mailing list, that's okay. Contact the CRL Talks organizer for the details.
Speakers have given everything from practice talks for conferences, job talks, or degree requirements to any new research they want feedback from the CRL community on! Talks are typically 45 min with ~10 min for questions. We love hearing from new grad students and faculty, but you are always welcome to present again! If you, anyone in your lab, or anyone visiting you is interested please let me know so I can arrange dates with them!
If you have someone you would like to hear from, we always enjoy suggestions of who to invite to speak as well!
We have been hoping to encourage more in-person participation/presentation, but there is a Zoom option available for those unable to join in person!
If you would like to send a message to the CRL community, please email it to crl@ucsd.edu (note all messages need to be approved by one of our managerial staff).
