The morphosyntactic nature of word accents in Swedish makes them a perfect candidate for the study of predictive processing in language. The association of word stem accents with upcoming suffixes ...allows native listeners to pre-activate a word's potential ending and thereby facilitate speech processing. Unlike native speakers, second language learners are known to be less able to use prediction in their L2s. This is presumably due in particular to competing information from the learners' L1 and a poorer exposure to the relevant L2 information. Swedish word accents, however, are abundant in the input and rare cross-linguistically, making them ideal for studying the implicit acquisition of linguistic prediction in beginner L2 learners. We therefore recorded learners' electrophysiological brain responses to Swedish word accents and compared them to those of native speakers. In the native speaker group, a pronounced suffix-related PrAN (pre-activation negativity), N400 and a P600-like late positivity indicate predictive processing. The learners, however, only produced a late (400–600 ms) centrally distributed negativity for word accent processing, remarkably similar to the deflection for pure pitch height differences found in the same subject group. Crucially, correlation analysis indicated that this negativity increased (at right-lateral electrode sites) for learners with increased level of Swedish proficiency. We conclude that, to allow L2 tone-suffix association and to enable its predictive capacity, the acquisition of Swedish word accents and their predictive properties might first involve dissociation of word tones from the default L1 tonal patterns as well as sensitisation to pitch height differences.

Swedish native speakers (NSs) unconsciously use tones realized on word stems to predict upcoming suffixes during speech comprehension. The present response time study investigated whether relatively ...proficient second language (L2) learners of Swedish have acquired the underlying association between tones and suffixes without explicit instruction, internalizing a feature that is specific to their L2. Learners listened to sentences in which the tone on the verb stem either validly or invalidly cued the following present or past tense inflection. Invalidly cued suffixes led to increased decision latencies in a verb tense identification task, suggesting that learners pre-activated suffixes associated with stem tones in a manner similar to NSs. Thus, L2 learners seemed to have acquired the tone-suffix connections through implicit mechanisms. Correctly cued suffixes were associated with a smaller processing advantage in the L2 group relative to NSs performing the same task; nevertheless, results suggest a tendency for increasingly native-like tone processing with cumulative language experience. The way suffix type affected response times also indicates exposure-related effects.
The present response time study investigated the influence Central Swedish word accents have on the interpretation of inflectional morphology. Effects of stem tone match/mismatch on the ...interpretation of Swedish present and past tense suffixes were tested. Both Accent 1 and Accent 2 were found to influence listeners’ response times related to decisions on verb tense. It thus seems that both word accents can facilitate online interpretation of words. Previous studies where tasks have not required suffix interpretation have only found an effect of Accent 1 patterns on Accent 2-associated suffixes. Accent 2 suffixes further yielded generally greater response times than Accent 1-associated suffixes. Different possible explanations for this are discussed.
Main purpose of this study is to find and build a model of Japanese accent perception practice at Japanese lessons in regular classrooms and those based on utilization of network and multimedia. ...Until now, Japanese phonetic researchers and teachers had to spend a disproportionate amount of time and effort to conduct experiments or test, and to develop the means to process resulting data of the experiments conducted. With the proposed AJ-phonetic Test system, accent tests are conducted online. In this respect, Japanese learners can take part in the phonetics experiment in a time and location convenient to them. Also, researchers and teachers can work on the obtained data by using the database available. Moreover, AJ-phonetic test feedbacks provide not only test results but also a more comprehensive data analysis. Results of the 12-year operation of AJ-phonetic test in Korea proved to have a positive effect on students as well as teachers. This paper present general guidelines necessary to conduct the AJ-phonetic test. Firstly, in case of Korean learners of Japanese, a separate set of words accentless pitch and those with accent pitch is needed because the two sets present different difficulty levels for a learner. Secondly, as the number of moras in a word affects the difficulty, we introduced dummy words, which proved successful in controling the level of difficulty and increasing learning effect. Besides, dummy words worked well as a substitute for low tone (frequency) long words as well for long words in general. Thirdly, since there are only few cases with a distinctive long-short opposition in Korean, Korean learners of Japanese have difficulties recognizing accents in words with special moras. Such words therefore need special attention. Finally, the ability of Korean learners of Japanese to recognize accent in Japanese words differs based of the learners’ native dialects. Best results were obtained by learners from the Jeonla-do region, followed by those from Gyeongsang-do region, while learners from Seoul had most difficulties in recognizing the accent. From all the above findings we conclude that Japanese accent education is highly necessary, and that in the process of education, both Japanese accent characteristics as well as learners’ native dialects should be considered.
•Swedish word accents can be used as a measure of perceptual phonological proficiency.•Cortical thickness and surface area correlate with perceptual phonological proficiency.•Swedish word accents ...influence word and phrase recognition in the ventral speech processing stream.
Lack of methods to experimentally assess the perceptual processing of sound features and allow one to measure differences in phonological proficiency has been a limitation for speech processing studies in native speakers. Tonal features associated with Swedish word-stems, word accents, which cue grammatical suffixes, constitute, however, such sound features that can be exploited to generate measures of reliance on morphosyntactically relevant phonological information during word processing. Specifically, there is a natural variance between native speakers in response time (RT) difference between phonologically valid and invalid word accent-suffix combinations that can be used to quantify perceptual phonological proficiency. This study uses ultra-high field magnetic resonance imaging (MRI) to investigate word accents as phonological cues to morphosyntactic meaning. The study adds to the understanding of the neural basis for both morphosyntactically relevant phonological cues by reporting correlations between differences in listeners’ RT for validly and invalidly cued suffixes and cortical thickness in left anterior and middle temporal gyrus, and the left anterior superior temporal sulcus as well as cortical surface area in the left middle and inferior temporal gyri. The cortical areas studied are known constituents of the ventral speech processing stream, necessary for word and phrase recognition.
This study investigates the multimodal implementation of prosodic-phonological categories, asking whether the accentual fall and the following rise in the Swedish word accents (Accent 1, Accent 2) ...are varied as a function of accompanying head and eyebrow gestures. Our purpose is to evaluate the hypothesis that prominence production displays a cumulative relation between acoustic and kinematic dimensions of spoken language, especially focusing on the clustering of gestures (head, eyebrows), at the same time asking if lexical-prosodic features would interfere with this cumulative relation. Our materials comprise 12 minutes of speech from Swedish television news presentations. The results reveal a significant trend for larger fo rises when a head movement accompanies the accented word, and even larger when an additional eyebrow movement is present. This trend is observed for accentual rises that encode phrase-level prominence, but not for accentual falls that are primarily related to lexical prosody. Moreover, the trend is manifested differently in different lexical-prosodic categories (Accent 1 versus Accent 2 with one versus two lexical stresses). The study provides novel support for a cumulative-cue hypothesis and the assumption that prominence production is essentially multimodal, well in line with the idea of speech and gesture as an integrated system.
•Word tones cueing suffixes (“word accents”) engage left-lateralized brain areas.•The brain distinguishes different word accents within 136ms of tone onset.•Left A1 and STG correlate in subject ...variability with brain potentials at 136ms.•Subject variability in IFG correlates with neural responses at 136ms and 256ms.•Rapid connection of tone and suffix representations in STG and IFG is proposed.
Previous studies distinguish between right hemisphere-dominant processing of prosodic/tonal information and left-hemispheric modulation of grammatical information as well as lexical tones. Swedish word accents offer a prime testing ground to better understand this division. Although similar to lexical tones, word accents are determined by words’ morphosyntactic structure, which enables listeners to use the tone at the beginning of a word to predict its grammatical ending. We recorded electrophysiological and hemodynamic brain responses to words where stem tones matched or mismatched inflectional suffixes. Tones produced brain potential effects after 136ms, correlating with subject variability in average BOLD in left primary auditory cortex, superior temporal gyrus, and inferior frontal gyrus. Invalidly cued suffixes activated the left inferior parietal lobe, arguably reflecting increased processing cost of their meaning. Thus, interaction of word accent tones with grammatical morphology yielded a rapid neural response correlating in subject variability with activations in predominantly left-hemispheric brain areas.
This article discusses the syntax–prosody interface, drawing on evidence from Stockholm Swedish. It is shown that a Swedish main clause containing an embedded clause has three prosodic correlates, ...two of which are non-isomorphic to the syntactic bracketing. However, two coordinated clauses have only one – isomorphic – prosodic correlate. Optimality-theoretic constraints (Prince & Smolensky 1993) are used to derive this variation. A new markedness constraint, EqualSisters, is argued to be responsible for a preference for flat prosodic structures. This constraint requires that sister nodes in prosodic structure belong to the same prosodic category, and therefore sometimes conflicts with match constraints, which call for syntax–prosody correspondence (Selkirk 2009, 2011). When high-ranked, EqualSisters forces syntax–prosody non-isomorphism if the input syntactic structure contains embedding, whereas full isomorphism is predicted in coordinated structures. The previously suggested markedness constraints Non-recursivity and Exhaustivity (Selkirk 1996) cannot replace EqualSisters, and in the present account are rendered redundant.
This paper considers how general linguistics can shed new light on the structure of Japanese, on the one hand, and how empirical and theoretical studies of Japanese dialects can contribute to the ...development of general linguistics, on the other. It tackles this question by analyzing several phonological phenomena in Japanese that are related to word accent in one way or another. This includes the accent of standard Tokyo Japanese and various processes that conspire to avoid creating superheavy syllables. Various seemingly unrelated phenomena can be generalized by introducing the notion of syllable weight into Japanese phonology; moreover, analyzing Japanese phenomena helps us widen our perspectives about the overall diversity of languages. Along these lines, the second half of this paper discusses accentual analyses of various Japanese dialects. These considerations demonstrate the extent to which studies on Japanese dialects and general linguistics can be related to each other.*
