Polish language has an uncommon three-way sibilant contrast /s, ʂ, ɕ/. For learners of Polish who have an L1 system that has two-way sibilant contrast (e.g., /s, ʃ/), this means that they must learn two segments (i.e., /ʂ, ɕ/) that are acoustically and perceptually similar to one L1 segment. In this study, we examined 5 A-level and 5 C-level L2 lea...

This poster examines the production and perception of L2 learners of the three-way sibilant contrast in Polish. The findings indicate that learners utilize L1 articulatory patterns to facilitate the learning of novel segments and that perceptually similar segments in L1 and L2 become linked over time with a shared representation.

Liquids, comprised of rhotics and laterals, are complex segments that pattern together across languages with respect to phonological and phonotactic behavior. However, there has been little if any unifying phonetic properties. This sets apart the liquids from other classes where there are clear phonetic correlates. Some researchers have suggested t...

Hindi, an Indo-Aryan language is the national language of India and the state language of various North Indian states of India such as Madhya Pradesh, Delhi, Uttar Pradesh etc. Statistics on the phonemes of a language provides useful information in the field of speech language pathology, audiology, linguistics and communication engineering. The dat...

Speech production system experiences complex dynamic tongue movements for the production of retroflexes. This makes retroflexes distinct from other phonemes. Present study aimed to analyze the articulatory dynamics and coarticulatory pattern of retroflexes across three major languages of India: Hindi, Kannada, and Malayalam. Ninety adult speakers h...

An examination of 7 fricatives in the perceptual space of English and Malayalam listeners. The aim is to see if phonological subgroups of fricatives group together in the perceptual space and support the notion that natural classes are dictated - at least in part - by perceptual characteristics.

No PDF available ABSTRACT The internal representation of linguistic information has been the subject of much debate. Recent work has shown that brain activation in response to different categories of segments, such as obstruents or approximants, triggers different neural networks. This work examines the perception of English and Malayalam native sp...

The perception of liquids in Mandarin and Hindi.

Rhotics and laterals are often described as being separated by F3; however, recent work has described lower F2 as a distinguishing quality of rhotics. The current work examines the perception of liquids (rhotics and laterals) by Mandarin and Hindi listeners. Participants completed a forced-choice identification task on a set of 30 stimuli, manipula...

Coarticulatory effect of nasal phonemes studied in short distance extensively. However, low frequency energy of nasal phoneme has a capacity of extent its effect for a longer distance. Also occurrence of nasal vowel is not common among feature in Indian languages. Hence, the present study indented to concentrate on the extent of influence of nasali...

em> The term 'coarticulatory resistance' refers to the degree to which a given segment, a consonant or a vowel, resists potential interference of neighbouring segments. The phoneme has coarticulatory resistance exert stronger influence on neighbouring phoneme and exhibit less contextual variation, this characteristic termed as 'coarticulatory aggre...

Childhood Apraxia of Speech (CAS) is a subtype of speech sound disorder with unique features that include deficits in speech sound accuracy, prosody, coarticulatory transitions, and consistency on repeated attempts. Articulatory errors are abundant in apraxia such as articulatory groping, perseverative errors, and speech initiation difficulties. Th...
