Emerging Phonology Under Language Contact: The Case of Sino-Russian Idiolects

The main aim of this study is to examine what kind of phonological system emerges because of language contact wherein adult speakers of L1 (Chinese) attempt to speak L2 (Russian) without any previous instruction in L2. The main findings of this study are as follows: a) The speakers of L1 largely adopt the phonetic inventory and phonotactics of L2 and b) the only underlying (distinctive) features in the emerging phonological system are those of place of articulation while voicing plays no distinctive role in the emerging phonological system of Chinese speakers. Moreover, the speakers of L1 faithfully replicate the stress system of L2, even though L1 (Chinese) is a tonal language and L2, Russian, is a stress language. The most important finding of this study is that speakers of L1 discern the entity ‘word’ in L2. The emerging phonological system is geared towards assuring the identifiability of words in L2 rather than towards consistency of phonological rules.

FORWARDING THE PLACE OF ARTICULATION OF THE DARGIN LANGUAGE

In the dialects of the Dargin language, the phonetic process of moving the place of articulation of posterior consonants (palatalization) under certain conditions is noted, due to which there are noticeable differences in the vocabulary of these dialects and dialects. Based on the lexical materials of a number of dialects of the Dargin language, this article identifies the phonetic positions in which these sound transitions occur.

More on the articulation of devoiced [u] in Tokyo Japanese: effects of surrounding consonants

Past work investigating the lingual articulation of devoiced vowels in Tokyo Japanese has revealed optional but categorical deletion. Some devoiced vowels retained a full lingual target, just like their voiced counterparts, whereas others showed trajectories that are best modelled as targetless, i.e., linear interpolation between the surrounding vowels. The current study explored the hypothesis that this probabilistic deletion is modulated by the identity of the surrounding consonants. A new EMA experiment with an extended stimulus set replicates the core finding of Shaw, Jason & Shigeto Kawahara. 2018b. The lingual gesture of devoiced [u] in Japanese. Journal of Phonetics 66. 100–119. DOI:https://doi.org/10.1016/j.wocn.2017.09.007 that Japanese devoiced [u] sometimes lacks a tongue body raising gesture. The current results moreover show that surrounding consonants do indeed affect the probability of tongue dorsum targetlessness. We found that deletion of devoiced vowels is affected by the place of articulation of the preceding consonant; deletion is more likely following a coronal fricative than a labial fricative. Additionally, we found that the manner combination of the flanking consonants, fricative–fricative versus fricative–stop, also has an effect, at least for some speakers; however, unlike the effect of C1 place, the direction of the manner combination effect varies across speakers with some deleting more often in fricative–stop environments and others more often in fricative–fricative environments.

Lexical Category-Governed Neutralization to Coronal and Non-Coronal Place of Articulation in Latent Consonants: The Case of Shipibo-Konibo and Capanahua (Pano)

This study documents and accounts for the behavior of the place of articulation of latent segments in the Panoan languages Shipibo-Konibo and Capanahua. In these languages, the lexical category of the word governs the place of articulation (PoA) of latent consonants. Latent segments only surface when they are syllabified as syllable onsets. They surface as coronal consonants when they are part of verbs; but they occur as non-coronal consonants when they belong to nouns or adjectives. In non-verb forms, by default, they are neutralized to dorsal in Shipibo-Konibo, and to labial in Capanahua. The analysis proposed consists in using the well-known markedness hierarchy on PoA, |Labial, Dorsal > Coronal > Pharyngeal|, and harmonically aligning it with a morphological markedness hierarchy in which non-verb forms are more marked than verb forms: |NonVerb > Verb|. This creates two fixed rankings of markedness constraints: one on verb forms in which, as expected, coronal/laryngeal is deemed the least marked PoA, and another one on non-verb forms in which the familiar markedness on PoA is reversed so that labial and dorsal become the least marked places of articulation. The study shows that although both Panoan languages follow the general cross-linguistic tendency to have coronal as a default PoA, this default can be overridden by morphology.

Lip movements enhance speech representations and effective connectivity in speech dorsal stream and its relationship with neurite architecture

Lip movements facilitate speech comprehension, especially under adverse listening conditions, but the neural mechanisms of this perceptual benefit at the phonemic and feature levels remain unclear. This fMRI study addresses this question by quantifying regional multivariate representation and network organization underlying audiovisual speech-in-noise perception. We found that valid lip movements enhanced neural representations of phoneme, place of articulation, or voicing feature of speech differentially in dorsal stream regions, including frontal speech motor areas and supramarginal gyrus. Such local changes were accompanied by strengthened dorsal stream effective connectivity. Moreover, the neurite orientation dispersion of left arcuate fasciculus, a structural basis of speech dorsal stream, predicted the visual enhancements of neural representations and effective connectivity. Our findings provide novel insight to speech science that lip movements promote both local phonemic and feature encoding and network connectivity in speech dorsal pathway and the functional enhancement is mediated by the microstructural architecture of the circuit.

Perception of Incongruent Audiovisual Speech: Distribution of Modality-Specific Responses

Purpose Multimodal sensory integration in audiovisual (AV) speech perception is a naturally occurring phenomenon. Modality-specific responses such as auditory left, auditory right, and visual responses to dichotic incongruent AV speech stimuli help in understanding AV speech processing through each input modality. It is observed that distribution of activity in the frontal motor areas involved in speech production has been shown to correlate with how subjects perceive the same syllable differently or perceive different syllables. This study investigated the distribution of modality-specific responses to dichotic incongruent AV speech stimuli by simultaneously presenting consonant–vowel (CV) syllables with different places of articulation to the participant's left and right ears and visually. Design A dichotic experimental design was adopted. Six stop CV syllables /pa/, /ta/, /ka/, /ba/, /da/, and /ga/ were assembled to create dichotic incongruent AV speech material. Participants included 40 native speakers of Norwegian (20 women, M age = 22.6 years, SD = 2.43 years; 20 men, M age = 23.7 years, SD = 2.08 years). Results Findings of this study showed that, under dichotic listening conditions, velar CV syllables resulted in the highest scores in the respective ears, and this might be explained by stimulus dominance of velar consonants, as shown in previous studies. However, this study, with dichotic auditory stimuli accompanied by an incongruent video segment, demonstrated that the presentation of a visually distinct video segment possibly draws attention to the video segment in some participants, thereby reducing the overall recognition of the dominant syllable. Furthermore, the findings here suggest the possibility of lesser response times to incongruent AV stimuli in females compared with males. Conclusion The identification of the left audio, right audio, and visual segments in dichotic incongruent AV stimuli depends on place of articulation, stimulus dominance, and voice onset time of the CV syllables.

EFL Students’ Pronunciation Problems in Presenting Thesis Proposal at Tertiary Level of English Department

The aim of the research is to investigate EFL Students’ Pronunciation Problems in Presenting Thesis Proposal at Tertiary Level of English Department. This qualitative study reported in this article focused on segmental features problems. The instruments used to collect the data needed in this study were the researcher, recording, and Dictionary. The data analysis covered consonant and vowel pronunciation problems. was based on the theories of phonetics proposed by George Yule and Jacobs, which embraces voicing, manner of articulation and place of articulation for English consonant production and the tongue part and position, sound length, and mouth forming for English vowel production. The result of the study shows that the research subject encountered a number of segmental pronunciation problems consisting of consonants and vowels including pure vowels and diphthongs. Furthermore, this research revealed that the problem with consonant sounds were the substitution of the sounds [v], [ð], [θ], [t∫], [ʒ], [ʃ] [z] and the deletion of the sounds [k], [ɡ], [t], and [s]. The problem with pure vowel sounds were the substitution of the sound [ɪ], [iː], [ɛ], [ʊ], [ʌ], [ɜː], [ɒ], [ɔː] and [ə] and the insertion of the sound [ə] between two consonant sounds. The problem with diphthongs were: the monophthongization of the sound [aɪ], [aʊ], [eɪ], [ɪə], [əʊ], and the replacement of the sounds [eɪ] and [ɪə] with other diphthongs. It is suggested for the next researchers to investigate pronunciation problems related to supra-segmental aspects and phonemic opposition. and factors driving pronunciation problems in the EFL Classroom setting.

Articulatory settings and L2 English coronal consonants

Background/aims: We explore the potential contribution of Articulatory Settings (AS) theory to L2 speech production research, testing the hypothesis that L2 segmental speech learning should involve a gradual, overall shift in both place and constriction degree, simultaneously affecting all consonants of a series as opposed to a set of parallel but unrelated changes in learners’ production of individual sounds. Methods: We conducted an electropalatography study of four francophone learners’ production of French and English word-initial and -medial /t d s z n l/ via carrier-sentence reading tasks. Results: L1–L2 differences in tongue shape are more common than those in constriction location, first and foremost for sonorants, and, thus, our results are not completely consistent with AS theory’s claims. Conclusions: AS theory provides a potentially rich framework for exploring the L2 speech learning of consonantal phenomena including low-level L1–L2 differences in place of articulation. We propose that the observed lack of systematic between-language articulatory differences could be attributed to a number of factors to be explored in future research, such as the targeting of voicing and manner differences before the adjustment of small place differences as well as individual patterns of entrenchment of L1 articulatory routines.

Orthogonal neural codes for speech in the infant brain

Creating invariant representations from an everchanging speech signal is a major challenge for the human brain. Such an ability is particularly crucial for preverbal infants who must discover the phonological, lexical, and syntactic regularities of an extremely inconsistent signal in order to acquire language. Within the visual domain, an efficient neural solution to overcome variability consists in factorizing the input into a reduced set of orthogonal components. Here, we asked whether a similar decomposition strategy is used in early speech perception. Using a 256-channel electroencephalographic system, we recorded the neural responses of 3-mo-old infants to 120 natural consonant–vowel syllables with varying acoustic and phonetic profiles. Using multivariate pattern analyses, we show that syllables are factorized into distinct and orthogonal neural codes for consonants and vowels. Concerning consonants, we further demonstrate the existence of two stages of processing. A first phase is characterized by orthogonal and context-invariant neural codes for the dimensions of manner and place of articulation. Within the second stage, manner and place codes are integrated to recover the identity of the phoneme. We conclude that, despite the paucity of articulatory motor plans and speech production skills, pre-babbling infants are already equipped with a structured combinatorial code for speech analysis, which might account for the rapid pace of language acquisition during the first year.

Calibration of Consonant Perception to Room Reverberation

Purpose We examined how consonant perception is affected by a preceding speech carrier simulated in the same or a different room, for different classes of consonants. Carrier room, carrier length, and carrier length/target room uncertainty were manipulated. A phonetic feature analysis tested which phonetic categories are influenced by the manipulations in the acoustic context of the carrier. Method Two experiments were performed, each with nine participants. Targets consisted of 10 or 16 vowel–consonant (VC) syllables presented in one of two strongly reverberant rooms, preceded by a multiple-VC carrier presented in either the same room, a different reverberant room, or an anechoic room. In Experiment 1, the carrier length and the target room randomly varied from trial to trial, whereas in Experiment 2, they were fixed within a block of trials. Results Overall, a consistent carrier provided an advantage for consonant perception compared to inconsistent carriers, whether in anechoic or differently reverberant rooms. Phonetic analysis showed that carrier inconsistency significantly degraded identification of the manner of articulation, especially for stop consonants and, in one of the rooms, also of voicing. Carrier length and carrier/target uncertainty did not affect adaptation to reverberation for individual phonetic features. The detrimental effects of anechoic and different reverberant carriers on target perception were similar. Conclusions The strength of calibration varies across different phonetic features, as well as across rooms with different levels of reverberation. Even though place of articulation is the feature that is affected by reverberation the most, it is the manner of articulation and, partially, voicing for which room adaptation is observed.
