We compare the complexity of idiosyncratic sound patterns involving American
English/ɹ/with the relative simplicity of clear/dark/l/-allophony patterns found in English and …

Ultrasound tongue imaging has become a promising technique for detecting covert
contrasts, due to the developments in data analysis methods that allow for processing …

This paper argues that inter-individual and inter-group variation in language acquisition,
perception, processing and production, rooted in our biology, may play a largely neglected …

This paper presents acoustic and articulatory data from prevocalic/r/in the non-rhotic variety

Abstract English/ɹ/is known to exhibit covert variability, with tongue postures ranging from
bunched to retroflex, as well as various degrees of lip protrusion and compression. Because …

Background There is a need to develop effective interventions and to compare the efficacy of
different interventions for children with residual speech‐sound errors (RSSEs). Rhotics (the r …

Purpose This study documented the efficacy of visual–acoustic biofeedback intervention for
residual rhotic errors, relative to a comparison condition involving traditional articulatory …

The traditional focus of variationist sociolinguistic research is the patterning of language
variation at the level of the community, which individual language users are said to learn …

Recent evidence suggests that the incorporation of visual biofeedback technologies may
enhance response to treatment in individuals with residual speech errors. However, there is …
