Although the TIMIT acoustic-phonetic dataset ([1], [2]) was created three decades ago, it remains in wide use, with more than 20000 Google Scholar references, and more than 1000 since 2017. Despite TIMIT's antiquity and relatively small size, inspection of these references shows that it is still used in many research areas: speech recognition, speaker recognition, speech synthesis, speech coding, speech enhancement, voice activity detection, speech perception, overlap detection and source separation, diagnosis of speech and language disorders, and linguistic phonetics, among others. Nevertheless, comparable datasets are not available even for other widely-studied languages, much less for underdocumented languages and varieties. Therefore, we have developed a method for creating TIMIT-like datasets in new languages with modest effort and cost, and we have applied this method in standard Thai, standard Mandarin Chinese, English from Chinese L2 learners, the Guanzhong dialect of Mandarin Chinese, and the Ga language of West Africa. Other collections are planned or underway. The resulting datasets will be published through the LDC, along with instructions and open-source tools for replicating this method in other languages, covering the steps of sentence selection and assignment to speakers, speaker recruiting and recording, proof-listening, and forced alignment.
Using the negated universal quantifiernot every, the study investigates the interpretations of scalar implicatures, lexical presuppositions, and implicated presuppositions by Thai children with autism spectrum disorders (ASDs; n= 32), comparedto their typically-developing (TD) peers (n= 70) and adults (n= 40). The results provide further empirical evidence to the literature (Chevallier et al. 2010, Hochstein et al. 2017, Pijnacker et al. 2009) that not only do adolescents with ASD perform on par with TD adolescents,children with ASD are also age-appropriate in their performance on deriving scalar implicatures. Despite the children with ASD's ability to compute scalar implicature, they still tend to give more logical, literal responses, compared to their peers. Compared to adults, both children with ASD and TD children still have a higher tendency to rely on the logical meaning rather than pragmatically inferred meaning. They are also less likely than adults to derive scalar implicatures, but equally likely to derive lexical presuppositions. No additive effects of implicated presuppositions are found in any group of the participants.
Reference of pronouns may be constrained via lexical presuppositions, includingmarked F-features, implicated presuppositions, and deictic center shifting in certain languages.This paper explores the acquisition of personal reference terms in Thai, a language that hasa highly complex personal reference system. The participants of the study were 67 typicallydevelopingchildren (TD) and 29 children with autism spectrum disorders (ASD), a populationwhich has long been observed to have difficulties with pronouns. The children were asked tocomplete simple production and comprehension tasks on personal reference terms. Overall,ASD children performed on par in production but significantly poorer in comprehension thanTD children. Given the freedom of choice in the production task, ASD children preferred usingfixed referential terms for self-reference, whereas TD children opted for personal pronouns. Interms of comprehension, ASD children were shown to generally be able to detect the personfeatures but they seemed to struggle the most with the pragmatic aspects of personal referenceterms. Our results support previous literature that lexical presuppositions are acquiredearlier than implicated presuppositions. We add to the literature that the types or the amount ofimplicated presuppositions matter in acquisition.Keywords: implicated presupposition, pragmatic inference, pronoun, personal reference, acquisition,deixis, Thai
We present results from two auditory experiments that examine priming effects for pseudo-derived pairs of words (e.g., corner-corn), as compared to morphologically, phonologically, and semantically related pairs. Previous work shows facilitation for pseudo-derived pairs in a visual masked priming paradigm; our Experiment 1 presents the novel finding that these effects are also found in auditory priming, with no consistent difference between pseudo-derived and phonologically-related pairs. Experiment 2 introduces an intervener between primes and targets to further probe the nature of the facilitation in pseudo-derived pairs. Implications for theories of morphological processing and spoken-word recognition are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
