    已提出了可分离的输入和输出语音工作记忆(WM)容量,具有支持语音识别的输入能力和支持生产的输出能力。我们研究了输入与输入的作用。在叙事制作中输出语音WM,检查语速和代词比率-两种具有与语音WM相关的先前证据的度量。对于语速,对失语症患者进行的案例系列方法发现,在控制单词产生后,输入或输出语音WM能力没有显着的独立贡献。对于代词比率,有人暗示输入语音WM的作用。因此,这两个发现都不支持输出语音缓冲区在语音制作中的特定作用。相比之下,两个案例证明了输入和输出语音WM能力之间的分离,为叙事产生的预测差异提供了暗示性证据,尽管需要后续研究。案例系列与案例系列的含义讨论了案例研究方法。
    Separable input and output phonological working memory (WM) capacities have been proposed, with the input capacity supporting speech recognition and the output capacity supporting production. We examined the role of input vs. output phonological WM in narrative production, examining speech rate and pronoun ratio - two measures with prior evidence of a relation to phonological WM. For speech rate, a case series approach with individuals with aphasia found no significant independent contribution of input or output phonological WM capacity after controlling for single-word production. For pronoun ratio, there was some suggestion of a role for input phonological WM. Thus, neither finding supported a specific role for an output phonological buffer in speech production. In contrast, two cases demonstrating dissociations between input and output phonological WM capacities provided suggestive evidence of predicted differences in narrative production, though follow-up research is needed. Implications for case series vs. case study approaches are discussed.

    重复经颅磁刺激(rTMS)可以增强失语症的恢复。大多数研究使用针对右额下回的抑制性刺激。然而,运动皮层,观察到有助于预测失语症恢复,参与单词制作,可能是rTMS的适当目标。我们旨在观察中风后失语症患者抑制性rTMS针对嘴唇的右运动皮层引起的图片命名任务的行为变化。
    使用单例实验设计,我们纳入了3名有语音缺陷的慢性卒中后失语症患者.每个参与者每周执行3次口头图片命名任务,持续2、3或4周(参与者之间的伪随机),以建立每个参与者的基线命名能力。这些不是治疗,没有提供反馈。然后,每个参与者都接受了干预,针对嘴唇右侧运动皮层的抑制性连续theta爆发刺激,每周3次,共2周。每周持续3次命名测试,这两个星期。在研究期间的任何时间都不进行治疗。
    图形的视觉分析显示了P2和P3的rTMS对图片命名精度的积极影响以及P1的改善趋势。统计分析表明,P1(τ=0.544,p=.013,SETau=0.288)和P2(τ=0.708,p=.001,SETau=0.235)的rTMS后有所改善。对于P3,即使干预允许一些改善,由于基线命名测试期间的学习效果,这在统计学上是不显着的,持续时间最长,4周关于特定的语言特点,所有患者的语音错误均显着减少。
    嘴唇的运动皮层可能是rTMS的适当目标,以改善患有语音缺陷的中风后失语症患者的命名。这表明有可能个性化rTMS的目标,根据患者的语言障碍。
    UNASSIGNED: Repetitive transcranial magnetic stimulation (rTMS) can enhance aphasia recovery. Most studies have used inhibitory stimulation targeting the right inferior frontal gyrus. However, the motor cortex, observed to contribute to the prediction of aphasia recovery, is involved in word production and could be an appropriate target for rTMS. We aimed to observe behavioral changes in a picture naming task induced by inhibitory rTMS targeting the right motor cortex of the lips in people with poststroke aphasia.
    UNASSIGNED: Using a single-case experimental design, we included three participants with chronic poststroke aphasia who had phonological deficits. Each participant performed a verbal picture naming task 3 times a week for 2, 3, or 4 weeks (pseudorandom across participants) to establish a baseline naming ability for each participant. These were not therapy sessions, and no feedback was provided. Then, each participant received the intervention, inhibitory continuous theta burst stimulation targeting the right motor cortex of the lips, 3 times a week for 2 weeks. Naming testing continued 3 times a week, for these latter 2 weeks. No therapy was performed at any time during the study.
    UNASSIGNED: Visual analysis of the graphs showed a positive effect of rTMS for P2 and P3 on picture naming accuracy and a tendency toward improvement for P1. Statistical analysis showed an improvement after rTMS for P1 (τ = 0.544, p = .013, SETau = 0.288) and P2 (τ = 0.708, p = .001, SETau = 0.235). For P3, even if the intervention allowed some improvement, this was statistically nonsignificant due to a learning effect during the baseline naming testing, which lasted the longest, 4 weeks. Regarding specific language features, phonological errors significantly decreased in all patients.
    UNASSIGNED: The motor cortex of the lips could be an appropriate target for rTMS to improve naming in people with poststroke aphasia suffering from a phonological deficit. This suggests the possibility to individualize the target for rTMS, according to the patient\'s linguistic impairment.

    非单词重复(NWR)已被描述为发育性语言障碍(DLD)的临床标记,由于NWR任务在语言上始终区分DLD和典型开发(TD),粤语是唯一的例外。这项研究通过报告一组新颖的NWR刺激来重新检查NWR是否能够在讲广东话的儿童中产生TD/DLD组差异,这些刺激考虑了已知影响NWR表现和组分化的因素,包括词汇,亚词汇性,长度,和音节的复杂性。
    16名DLD的粤语儿童和16名TD的年龄匹配儿童重复两组高词性非单词,所有组成音节都是广东话的语素,但组合时毫无意义,和一组低词性非词,所有组成音节都是非语素的。根据辅音元音(CV)组合证明(无论非单词音节中的CV组合是否出现在真实的广东话中),低词性非单词被进一步分类为亚词性。
    患有DLD的儿童在TD上的得分明显低于同龄人。效果大小表明,具有经证明的CV组合的高词性非单词和非单词音节可提供最大的TD/DLD组差异。非词长度和音节复杂度不影响TD/DLD组分化。
    NWR可以捕获说广东话的儿童的TD/DLD组差异。在设计TD/DLD组分化的NWR刺激时,必须考虑词汇性和亚词汇性效应。未来的研究应该在更大的样本量和更年轻的人群中复制本研究,并检查该NWR测试的诊断准确性。

    UNASSIGNED: Nonword repetition (NWR) has been described as a clinical marker of developmental language disorder (DLD), as NWR tasks consistently discriminate between DLD and typical development (TD) cross-linguistically, with Cantonese as the only reported exception. This study reexamines whether NWR is able to generate TD/DLD group differences in Cantonese-speaking children by reporting on a novel set of NWR stimuli that take into account factors known to affect NWR performance and group differentiation, including lexicality, sublexicality, length, and syllable complexity.
    UNASSIGNED: Sixteen Cantonese-speaking children with DLD and 16 age-matched children with TD repeated two sets of high-lexicality nonwords, where all constituent syllables are morphemic in Cantonese but meaningless when combined, and one set of low-lexicality nonwords, where all constituent syllables are nonmorphemic. Low-lexicality nonwords were further classified on sublexicality in terms of consonant-vowel (CV) combination attestedness (whether or not CV combinations in nonword syllables occur in real Cantonese words).
    UNASSIGNED: Children with DLD scored significantly below their peers with TD. Effect sizes showed that high-lexicality nonwords and nonword syllables with attested CV combinations offered the greatest TD/DLD group differentiation. Nonword length and syllable complexity did not affect TD/DLD group differentiation.
    UNASSIGNED: NWR can capture TD/DLD group differences in Cantonese-speaking children. Lexicality and sublexicality effects must be considered in designing NWR stimuli for TD/DLD group differentiation. Future studies should replicate the present study on a larger sample size and a younger population as well as examine the diagnostic accuracy of this NWR test.

    Autism Spectrum Disorder (ASD) is classified by Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a neurodevelopmental disorder, whose characteristics are mainly deficits in social communication and a restricted range of interests. There are several studies about autism, speech, and language in the literature, but few correlate speech and autism. This study aims to carry out a case study that will address autism, speech, and PROMPT (Restructuring Oral Muscular Phonetic Targets) and also to describe the speech improvement in the participant with autism using the method. The target words were defined for the entire intervention according to the System Analysis Observation (SAO) and Motor Speech Hierarchy (MSH), which are parts of the PROMPT evaluation. After the evaluation, the participant was attended for 16 sessions, once weekly, with the objective of improving their speech. After analyzing the data, it was possible to observe improvement in all aspects outlined according to the pre-treatment evaluation of the method such as phonatory control, mandibular control, lip-facial control and lingual control as well as in the sequenced movement although this was not the aim outlined in the evaluation. It was also possible to measure the improvement of an adequate number of words, an adequate number of phonemes, percentages of correct consonants - revised (PCC-R), and intelligibility.
    O Transtorno do Espectro Autista (TEA) é classificado pelo Manual de Diagnóstico e Estatístico de Transtornos Mentais (DSM-5) como um Transtorno do Neurodesenvolvimento, sendo caracterizado, principalmente, por alterações na comunicação social e pela presença de um repertório restrito de atividades e interesses. Na literatura, há muitos estudos sobre autismo, fala e linguagem, mas poucos correlacionando fala e autismo. Este estudo teve como finalidade realizar um estudo de caso que abordou autismo, fala e PROMPT (Pontos para a Reestruturação de Objetivos Fonéticos e Oro-Musculares) e mensurou a melhora da fala no participante com autismo, utilizando o método. Foram definidas palavras-alvo para toda a intervenção, conforme o Sistema de Observação e Análise (SOA) e Hierarquia Motora de Fala (HMF), que fazem parte da avaliação de PROMPT. Após a avaliação, o participante foi atendido por 16 sessões, uma vez semanalmente. Após análise dos dados, observou-se melhora em todos os aspectos que foram delineados de acordo com a avaliação no pré-tratamento, como controle fonatório, controle mandibular, controle lábio-facial e controle lingual, como também no movimento sequenciado, apesar deste não ser o objetivo traçado na avaliação. Também foi possível mensurar melhora no número de vocábulos adequados, número de fonemas adequados, porcentagens de consoantes corretas – revisado (PCC-R) e inteligibilidade.

    在韩语中,有声口腔停止可以作为其无声lenis对应物的异音音素而间断性地发生;它们最初也可以作为鼻塞的变体而发生,这是由于最初的变性(例如,/motu/→[bodu]\"all\")。然而,由于对韩语中的初始[]的音位限制,因此在初始位置都不允许[]和[](鼻状鼻部的变性变体)。鉴于韩语中鼻和浊音的分布,这项研究借鉴了线索信息的思想,探索(a)韩国听众对鼻音和发声线索的注意力是否基于鼻音和发声停止的分布特征,以及(b)在没有这种语言经验的情况下,他们的注意力是否可以跨越不同的衔接地点。在强制选择识别实验中,韩国听众比台湾听众更有可能将发声的口鼻停止连续上的项目感知为鼻,除了Velar停止。结果表明,韩国听众在内侧位置比在初始位置更可靠地注意鼻音提示,因为这个位置的鼻性线索由于最初的去碱化而信息较少。另外两个强制选择鉴定实验表明,在听到最初的鼻翼时,韩国听众可变地采用不同的感知策略(即,元音插入和位置更改)以修复语音非法。这些发现为语音感知的示例模型提供了支持,在该模型中,提示注意力特定于单词的位置,和分段而不是特征。
    In Korean, voiced oral stops can occur intervocalically as allophones of their voiceless lenis counterparts; they can also occur initially as variants of nasal stops as a result of initial denasalization (e.g., /motu/→[bodu] \"all\"). However, neither [ŋ] nor [ɡ] (the denasalized variant of the velar nasal) is allowed in the initial position due to the phonotactic restriction against initial [ŋ] in Korean. Given the distribution of nasal and voiced stops in Korean, this study draws on the idea of cue informativeness, exploring (a) whether Korean listeners\' attention to nasality and voicing cues is based on the distributional characteristics of nasal and voiced stops, and (b) whether their attention can be generalized across different places of articulation without such linguistic experience. In a forced-choice identification experiment, Korean listeners were more likely than Taiwanese listeners to perceive items on the voiced oral-to-nasal stop continua as nasal when they occurred in the initial position than in the intervocalic position, with the exception of velar stops. The results demonstrate that the Korean listeners attended to the nasality cue more reliably in the medial position than in the initial position, since the nasality cue in this position is less informative due to initial denasalization. Two additional forced-choice identification experiments suggested that upon hearing initial velar nasal [ŋ], Korean listeners variably employed different perceptual strategies (i.e., vowel insertion and place change) to repair the phonotactic illegality. These findings provide support for exemplar models of speech perception in which cue attention is specific to the position of a word, and to segments rather than to features.

    虽然形态意识之间的关系,语音意识,词汇被广泛观察,关于他们的精确关联仍然存在问题。本研究的目的是在具有丰富形态的透明拼字法中,探索形态意识与两种高度相关的语言技能(语音意识和词汇)之间的关系。研究样本由121名(58名男性,平均年龄=93.94个月,SD=3.32)二年级讲希腊语的儿童。验证性因子分析显示,三因素模型提供了对数据的最佳拟合,表明尽管形态意识,语音意识,和词汇高度相关,它们代表不同的语言结构。此外,分层回归分析用于检验三种语言技能之间的双向效应。结果表明,语音意识和词汇都显着促进了形态意识,语音意识有更强的效果。相反,形态意识显着影响语音意识和词汇。从语音意识和词汇到形态意识的影响大小与从形态意识到语音意识和词汇的影响大小相似。这些结果表明,形态意识与语音意识和词汇高度相关,虽然是一种独特的技能。此外,这些语言技能似乎在一年级时具有双向作用。
    Although relations between morphological awareness, phonological awareness, and vocabulary have been widely observed, questions remain about their precise associations. The purpose of the present study was to explore the relations of morphological awareness with two highly related linguistic skills (phonological awareness and vocabulary) in a transparent orthography with rich morphology. The study sample consisted of 121 (58 males, Mean age = 93.94 months, SD = 3.32) 2nd grade Greek-speaking children. Confirmatory factor analysis revealed that the three-factor model provided the best fit to the data, indicating that although morphological awareness, phonological awareness, and vocabulary are highly correlated, they represent distinct linguistic constructs. In addition, hierarchical regression analysis was used to examine the bidirectional effects between the three linguistic skills. Results revealed that both phonological awareness and vocabulary significantly contributed to morphological awareness, with phonological awareness having a stronger effect. Conversely, morphological awareness significantly affected both phonological awareness and vocabulary. The effect size from phonological awareness and vocabulary to morphological awareness was similar to the effect size reported from morphological awareness to phonological awareness and vocabulary. These results suggest that morphological awareness is highly associated with phonological awareness and vocabulary, being though a distinct skill. In addition, it seems that these linguistic skills have bidirectional effects with each other in first grades.

    Glossolalia可以被视为语音产生的一个实例,其中从业者以看似随机的序列产生音节。然而,仔细检查glossalalalia的统计特性,发现序列显示出类似于自然语言的Zipfian模式,有些音节比其他音节更可能。众所周知,序列的统计特性是隐式学习的,这些统计特性与运动学和言语行为的变化相关。为了演讲,这意味着更可预测的项目在语音上更短。因此,我们为glossolalia假设,如果从业者以与自然语言相同的方式在glossolalia中学习了串行模式,它的统计特性应该与其语音特征相关。我们的假设得到了支持。我们在glossolalia中发现明显较短的音节与较高的音节概率相关。我们结合有关语音信号中与概率相关的变化来源的理论来讨论这一发现。
    Glossolalia can be regarded as an instance of speech production in which practitioners produce syllables in seemingly random sequences. However, a closer inspection of glossalalia\'s statistical properties reveals that sequences show a Zipfian pattern similar to natural languages, with some syllables being more probable than others. It is well established that statistical properties of sequences are implicitly learned, and that these statistical properties correlate with changes in kinematic and speech behavior. For speech, this means that more predictable items are phonetically shorter. Accordingly, we hypothesized for glossolalia that if practitioners have learned a serial pattern in glossolalia in the same manner as in natural languages, its statistical properties should correlate with its phonetic characteristics. Our hypothesis was supported. We find significantly shorter syllables associated with higher syllable probabilities in glossolalia. We discuss this finding in relation to theories about the sources of probability-related changes in the speech signal.

    片段序列的非母语或第二语言(L2)感知通常以感知修饰过程为特征,通过将序列转换为在L1中在语音上合法的序列,可以“修复”在听众\'本地语言(L1)中在语音上非法的非本地序列。通常,修复涉及插入语音材料(表音),但我们集中注意力,在这里,通过使用跨语言优度评估任务的三角剖分方法测试L1普通话听众对L2英语中的后声词的感知,对非本地音素的感知删除现象进行了研究,AXB任务,AX任务在感知同化模型(PAM/PAM-L2)的框架内分析数据,我们进一步研究了二语词汇量对任务表现的作用。实验表明,就舌背度规范而言,当语音后侧面与核元音重叠时,会发生感知缺失。此外,普通话听众在某些情况下的歧视表现与他们的英语词汇量显著相关,表明词汇知识的持续增长可以驱动对新的L2片段序列和语音结构的感知学习。
    Nonnative or second language (L2) perception of segmental sequences is often characterised by perceptual modification processes, which may \"repair\" a nonnative sequence that is phonotactically illegal in the listeners\' native language (L1) by transforming the sequence into a sequence that is phonotactically legal in the L1. Often repairs involve the insertion of phonetic materials (epenthesis), but we focus, here, on the less-studied phenomenon of perceptual deletion of nonnative phonemes by testing L1 Mandarin listeners\' perception of post-vocalic laterals in L2 English using the triangulating methods of a cross-language goodness rating task, an AXB task, and an AX task. The data were analysed in the framework of the Perceptual Assimilation Model (PAM/PAM-L2), and we further investigated the role of L2 vocabulary size on task performance. The experiments indicate that perceptual deletion occurs when the post-vocalic lateral overlaps with the nucleus vowel in terms of tongue backness specification. In addition, Mandarin listeners\' discrimination performance in some contexts was significantly correlated with their English vocabulary size, indicating that continuous growth of vocabulary knowledge can drive perceptual learning of novel L2 segmental sequences and phonotactic structures.

    婴儿从言语前阶段开始使用基于统计的分词策略。统计分割是,然而,受发作偏差的约束,一种语言通用原则,不利于损害音节完整性的分割。儿童最终会学习这一原则的特定语言例外。例如,在法语联络上下文中,元音起始词发生子音节解析,也就是说,当一个单词的最终辅音表面为以下单词的音节开始时(例如,/n/inun/n/éléphant)。在过去的研究中,法语学习的24个月大学生成功解析了带有可变联络辅音的元音初始伪词。这项研究进一步调查了婴儿联络代表,它对解析的潜在影响,以及它与发作偏差的相互作用。在实验1和2中,学习法语的24个月大学生熟悉具有可变联络状和非联络状起始辅音的伪词,前面有不能触发这些开始的单词(例如,联合国包车;联合国包车)。我们没有发现错误分割为元音初始,而成功分割为辅音初始。在实验3中,当前面的单词可以触发与后面单词的开始相匹配的联络辅音时(例如,UNnonche),婴儿表现出元音开头的错误解释,反对发作的偏见,揭示联络知识的影响。这些结果表明,幼儿在早期习得过程中平衡了他们对语言一般原则/策略和语言特定知识的使用。
    Infants use statistics-based word segmentation strategies from the preverbal stage. Statistical segmentation is, however, constrained by the Onset Bias, a language-universal principle that disfavors segmentation that harms syllable integrity. Children eventually learn language-specific exceptions to this principle. For instance, sub-syllabic parsing occurs for vowel-initial words in French liaison contexts, that is, when a word\'s final consonant surfaces as the following word\'s syllabic onset (e.g., /n/ in un /n/éléphant). In past research, French-learning 24-month-olds succeeded in parsing a vowel-initial pseudo-word surfacing with variable liaison consonants. This study further investigated infants\' liaison representation, its potential impacts on parsing, and its interaction with the Onset Bias. In Experiments 1 and 2, French-learning 24-month-olds were familiarized with pseudo-words with variable liaison-like versus nonliaison-like onset consonants, preceded by words that cannot trigger those onsets (e.g., un zonche; un gonche). We found no mis-segmentation as vowel-initial and successful segmentation as consonant-initial. In Experiment 3, when the preceding words could trigger a liaison consonant that matched the onset of the following word (e.g., un nonche), infants showed a vowel-initial mis-interpretation, against the Onset Bias, revealing an effect of liaison knowledge. These results demonstrate that toddlers balance their use of language-general principles/strategies and language-specific knowledge during early acquisition.
