Complexity of vocal tract shaping in glossectomy patients and typical speakers: A principal component analysis

The Journal of the Acoustical Society of America · 2021 · 16 citations

The glossectomy procedure, involving surgical resection of cancerous lingual tissue, has long been observed to affect speech production. This study aims to quantitatively index and compare complexity of vocal tract shaping due to lingual movement in individuals who have undergone glossectomy and typical speakers using real-time magnetic resonance imaging data and Principal Component Analysis. The data reveal that (i) the type of glossectomy undergone largely predicts the patterns in vocal tract…

Variability in individual constriction contributions to third formant values in American English /ɹ/

The Journal of the Acoustical Society of America · 2020 · 7 citations

Although substantial variability is observed in the articulatory implementation of the constriction gestures involved in /ɹ/ production, studies of articulatory-acoustic relations in /ɹ/ have largely ignored the potential for subtle variation in the implementation of these gestures to affect salient acoustic dimensions. This study examines how variation in the articulation of American English /ɹ/ influences the relative sensitivity of the third formant to variation in palatal, pharyngeal, and la…

Direct articulatory observation reveals phoneme recognition performance characteristics of a self-supervised speech model

JASA Express Letters · 2024-11-01 · 3 citations

Variability in speech pronunciation is widely observed across different linguistic backgrounds, which impacts modern automatic speech recognition performance. Here, we evaluate the performance of a self-supervised speech model in phoneme recognition using direct articulatory evidence. Findings indicate significant differences in phoneme recognition, especially in front vowels, between American English and Indian English speakers. To gain a deeper understanding of these differences, we conduct re…
