Study for improving the coded speech by tight framelet packet transform In this paper we propose to study the performance of a new time-frequency representation called the tight framelet packets transform in speech coding. For this, we performed a comparative study with the wavelet packets transform. Performance evaluation was done …...

_________________________________________________________________________________________________________ Learning non-native contrasts: Limits of the statistical training Recently, studies showed that distributional information contained in the speech signal can contribute to the acquisition of phoneme categories. Indeed, exposition to bimodal distributions leads to an improvement of phoneme discrimination compared to unimodal distributions which did not improve speech perception. …...

_________________________________________________________________________________________________________ Variations of labial configuration of vowels /i, y, a/: effect of prosodic position and speaker. Variations in the labial configuration of the French vowels /i, y, a/ are observed on measurements derived from the external and internal contour of the lips. Articulatory variations according to vowel type, speakers and …...

what is the impact of the transcription on the phonetization This paper aims at quantifying the impact of the transcription enrichments on the automatic phonetization of speech. Experiments were carried out on a 7 minutes French corpus including conversational speech, readed speech and a political discourse. Results showed the better …...

_________________________________________________________________________________________________________ Voice assimilation in French: It applies to nonwords just like to words Recent studies on voice assimilation in French have addressed several important issues. Firstly, is this assimilation process gradient or categorical? Recent analyses of how distributions of voicing ratio change with assimilating to non-assimilating contexts suggest that assimilation …...

Cross-show speaker diarization We propose to study speaker diarization from a collection of audio documents. The goal is to detect speakers appearing in several shows. In our approach, shows are processed independently of each other before being processed collectively, to group speakers involved in several shows. Two clustering methods are …...

Speaker verification : results variation Speaker verification systems have shown significant progress and have reached a level of per- formance that make their use in practical applications possible. Nevertheless, large differences in terms of performance are observed, depending on the speaker or the speech sample used. This context emphasizes the …...

Detection of incorrect transcriptions of non-native speech in the context of foreign lan- guage learning This article analyses the detection of incorrect transcriptions of non-native speech in the context of foreign language learning. The purpose is to detect and reject incorrect transcriptions (i.e. those for which the text does not …...

_________________________________________________________________________________________________________ Towards assessing phonic compliance The paper is focused on “phonic compliance”, the ability of the subject to accurately reproduce speech sounds presented to him/her as production models. Three mathematical techniques are proposed to perform objective assessment. A pilot study is carried out on previously collected and original data. Each …...

_______________________________________________________ Speech Prosody of Dialectal French: Data and Hypotheses This paper contrasts the prosody of 6 varieties of French spoken in three different areas: France (Paris and Lyon), Belgium (Tournai and Liège), and Switzerland (Geneva and Neuchâtel). The objective is to address whether some prosodic criteria can help to classify …...

_________________________________________________________________________________________________________ The /y-u/ vowels in the IPFC project: a perceptual assessment of native, Spanish and Japanese learners’ productions. We present a perceptual study of the French vowels /y/ and /u/ produced by Spanish and Japanese learners, in the framework of the InterPhonology of Contemporary French (IPFC) project. To evaluate the …...

__________________________________________________________________________________________________________ Tongue control in 4-years-old children's speech production: A methodology combining articulatory study and biomechanical modeling An original methodology is proposed for the study of the emergence of speech motor control in 4-years-old children. We combine the results of an analysis of an articulatory and acoustic speech corpus containing isolated …...

Abnormal Zone Detection in Dysarthric Speech Utterances according to Frequency Bands This paper proposes to join a speech processing-based system devoted to the automatic detection of abnormal zones in impaired speech utterances with an analysis in frequency subbands. This work aims to demonstrate that abnormal zones could be detected differently …...

_______________________________________________________________________________________________ Effect of phonological neighborhood density on lexical retrieval in the spontaneous speech of patients with Alzheimer’s disease Lexical access failure is an early marker of Alzheimer’s disease, which is often accounted for by the loss of semantic representations while phonological aspects are considered more resistant. Phonological neighborhood density, which …...

_______________________________________________________________________________________________ Perception of boundaries and prominences in French This paper investigates boundary and prominence phenomena in French through a perception study, in order to go beyond the view that these phenomena are similar underlying phenomena in French. Our analyses focus on Final Accents (FA) and Initial Accents (IA) as right …...

_________________________________________________________________________________________________________ Voicing contrast in whispered speech This paper presents analyses on the phonological voicing contrast in whispered speech, which is characterized by a semi-open configuration of the vocal folds preventing them from vibrating. In modal speech, in addition to vocal fold vibration, the contrast between voiced and unvoiced consonants is …...

_________________________________________________________________________________________________________ Masked semantic priming in cocktail party situation The present study aimed at testing automatic semantic processing in the auditory modality using the cocktail party situation. Participants had to perform a lexical decision task on a target item embedded in a multi-talker babble. This babble was made of voices pronouncing …...

Principal Component Analysis for i-vector extraction in speaker verification. In this work, we propose alternative algorithmic combinations for speaker verification based on the Total Variability paradigm. Experiments presented in this paper show that replacing Factor Analysis (FA) by a Principal Component Analysis (PCA) for super-vector dimensionality reduction can lead to …...

F0-declination : a comparison between French and German journalistic speech The aim of the present study is to investigate F0-declination over the course of utterances in French and German journalistic speech by using large transcribed and automatically segmented corpora (a total of about 80,000 utterances of more than 1,000 speakers). …...

_______________________________________________________________________________________________ Predictice control and coding of orofacial actions Predictice control and coding of orofacial actions Predictice control and coding of orofacial actions Predictice control and coding of orofacial actions Recent studies provide evidence for action goal coding of manual actions in premotor and posterior parietal cortices. To further extend these …...
