There is increasing evidence that fine articulatory adjustments are made by speakers to reinforce and sometimes counteract the acoustic consequences of nasality. However, it is difficult to attribute the acoustic changes in nasal vowel spectra to either oral cavity configuration or to velopharyngeal opening (VPO). This paper takes the position that it is(More)
Proceeding from the assumption that all languages are equally complex, there exists a corollary, widely held but poorly documented, herein referred to as the negative correlation hypothesis. It states: if one component of language is simplified then another must be elaborated. Here, this assumption is reformulated in terms of a scientific hypothesis and(More)
PURPOSE To enable dynamic speech imaging with high spatiotemporal resolution and full-vocal-tract spatial coverage, leveraging recent advances in sparse sampling. METHODS An imaging method is developed to enable high-speed dynamic speech imaging exploiting low-rank and sparsity of the dynamic images of articulatory motion during speech. The proposed(More)
In acoustic studies of vowel nasalization, it is sometimes assumed that the primary articulatory difference between an oral vowel and a nasal vowel is the coupling of the nasal cavity to the rest of the vocal tract. Acoustic modulations observed in nasal vowels are customarily attributed to the presence of additional poles affiliated with the(More)
Recent acoustic research has challenged the traditional understanding of the spirantization of Spanish /b d g/. We compare acoustic and EPG results on the realization of /d/ in different contexts. Whereas we largely confirm recent observations regarding the postfricative context, we also show that after nasals and laterals the intensity curve associated(More)
