resume: This present study investigated the link between speech-in-speech perception capacities and four executive function components: response suppression, inhibitory control, switching and working memory. We constructed a cross-modal semantic priming paradigm using a written target word and a spoken prime word, implemented in one of two concurrent auditory sentences (cocktail party situation). The prime and target were semantically related or unrelated. Participants had to perform a lexical decision task on visual target words and simultaneously listen to only one of two pronounced sentences. The attention of the participant was manipulated: The prime was in the pronounced sentence listened to by the participant or in the ignored one. In addition, we evaluate the executive function abilities of participants (switching cost, inhibitory-control cost and response-suppression cost) and their working memory span. Correlation analyses were performed between the executive and priming measurements. Our results showed a significant interaction effect between attention and semantic priming. We observed a significant priming effect in the attended but not in the ignored condition. Only priming effects obtained in the ignored condition were significantly correlated with some of the executive measurements. However, no correlation between priming effects and working memory capacity was found. Overall, these results confirm, first, the role of attention for semantic priming effect and, second, the implication of executive functions in speech-in-noise understanding capacities.

titre: Speech reductions cause a de-weighting of secondary acoustic cues

resume: The ability of the auditory system to change the perceptual weighting of acoustic cues when faced with degraded speech has long been evidenced. However, the exact changes that occur remain mostly unknown. Here, we proposed to use the Auditory Classification Image (ACI) methodology to reveal the acoustic cues used in natural speech comprehension and in reduced (i.e. noise-vocoded or re-synthesized) speech comprehension. The results show that in the latter case the auditory system updates its listening strategy by de-weighting secondary acoustic cues. Indeed, these are often weaker and thus more easily erased in adverse listening conditions. Furthermore our data suggests that this de-weighting does not directly depend on the actual reliability of the cues, but rather on the expected change in informativeness.

titre: The Brazilian Portuguese Lexicon: An Instrument for Psycholinguistic Research
auteur: Gustavo Estivalet, Fanny Meunier
article: PLoS ONE, Public Library of Science, 2015, 〈10.1371/journal.pone.0144016〉
annee_publi: 2015
resume: In this article, we present the Brazilian Portuguese Lexicon, a new word-based corpus for psycholinguistic and computational linguistic research in Brazilian Portuguese. We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Lin-guística Computacional's corpus as the basic data source and developed the Brazilian Por-tuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control , and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

titre: Multi-linguistic babble intelligibility for native and non-native listeners: Effect of concurrent language knowledge on lexical access.
auteur: Fanny Meunier, Aurore Gautreau
article: Speech Communication, Elsevier : North-Holland, 2015, 69 pp. 9-16
annee_publi: 2015
resume: This research examines the nature of the interference that occurs during speech-in-speech processing for late bilingual listeners. Native French-speaking listeners with Italian as their L2 performed a lexical decision task with French target words presented amid background speech (i.e., 4-talker babble) and nonspeech background noise (i.e., speech-shaped fluctuating noise). We compared the masking effects of babble generated in the listeners’ L1 (French), their L2 (Italian), or an unknown language (Irish) to the masking effects of corresponding fluctuating noise. The fluctuating noise contained spectro-temporal information similar to babble but lacked linguistic information. This design allowed us to compare lexical decision times obtained with the 2 kinds of background noise in each language and thus to assess the linguistic interference caused by babble. Results revealed that babble spoken in the known languages (French and Italian) produced both linguistic and acoustic interference and that babble spoken in the unknown language (Irish) produced acoustic interference only. Furthermore, the L1-French L2-Italian listeners were more strongly affected by the L2 babble than by the L1 babble.

titre: A Psychophysical Imaging Method Evidencing Auditory Cue Extraction during Speech Perception: A Group Analysis of Auditory Classification Images
auteur: Léo Varnet, Kenneth Knoblauch, Willy Serniclaes, Fanny Meunier, Michel Hoen
article: PLoS ONE, Public Library of Science, 2015, 〈10.1371/journal.pone.0118009〉
annee_publi: 2015
resume: Although there is a large consensus regarding the involvement of specific acoustic cues in speech perception, the precise mechanisms underlying the transformation from continuous acoustical properties into discrete perceptual units remains undetermined. This gap in knowledge is partially due to the lack of a turnkey solution for isolating critical speech cues from natural stimuli. In this paper, we describe a psychoacoustic imaging method known as the Auditory Classification Image technique that allows experimenters to estimate the relative importance of time-frequency regions in categorizing natural speech utterances in noise. Importantly , this technique enables the testing of hypotheses on the listening strategies of participants at the group level. We exemplify this approach by identifying the acoustic cues involved in da/ga categorization with two phonetic contexts, Al-or Ar-. The application of Auditory Classification Images to our group of 16 participants revealed significant critical regions on the second and third formant onsets, as predicted by the literature, as well as an unexpected temporal cue on the first formant. Finally, through a cluster-based nonparametric test, we demonstrate that this method is sufficiently sensitive to detect fine modifications of the classification strategies between different utterances of the same phoneme.
