__________________________________________________________________________________________________________ Pitch height in French: Gradual or categorical variations? This paper reports the results of an experiment on the question of whether the realizations of f0 variations at the end of the final IP are categorical or gradient. We conducted an imitation task with resynthesized stimuli where the final pitch …...

____________________________________________________________________________________________________________________ Laryngeal adjustments in French Laryngeal adjustments in French are examined based on non-invasive external photoglottographic (ePGG) data from two subjects. The aim is to determine how glottal opening amplitude and the timing between laryngeal and supralaryngeal gestures vary depending on the phonetic make-up of the voiceless obstruents. Specifically, we …...

Optimization of a tutoring system from a fixed set of data In this paper, we present a general method for optimizing a tutoring system with a target application in the domain of second language acquisition. More specifically, the optimisation process aims at learning the best sequencing strategy for switching between …...

_________________________________________________________ Inner speech monitoring deficit : a study of auditory verbal hallucinations Auditory verbal hallucinations (AVHs) are speech perceptions in the absence of relevant external stimuli. Some accounts of AVHs claim that a deficit in inner speech monitoring causes the own verbal thoughts of the patient to be perceived as …...

_______________________________________________________________________________________________ Spatio-temporal coordinations in Moroccan Arabic ab(bi) sequences In this study using 3-dimensional EMA (AG500 Carstens Medizinelektronik) we tried to characterize the temporal relations between consonant and vowels in [ab(b)i] contexts. We found that, [bb] has a consonantal gesture (LowerLip_y) whose total duration and plateau phase are longer and the …...

_________________________________________________________________________________________________________________ Distortions of vocalic space: which measurements? An application to dysarthria. This paper presents several metrics derived from F1/F2 measurements for the description and quantification of the possible variations to be observed in a vocalic space. 8 metrics from the literature or adapted to our data are evaluated on productions …...

__________________________________________________________________________________________________________ Speech clarity and coarticulatory effects in standard and dialectal Arabic This study deals with the co-variation of speech clarity and coarticulatory patterns. Two experiments were conducted to investigate the influence of two parameters, the speech style (formal vs. non formal) and the prosodic position (stressed vs. unstressed syllable). The …...

_________________________________________________________________________________________________________ Pitch estimation and voiced decision by spectral autocorrelation compression of multi-scale product In this work, we propose an algorithm for pitch estimation and voicing detection in clean and noisy speech signal. Our approach is based on the spectral compression (CS) of the autocorrelation of the multi-scale product (APM). The …...

An experimental framework for speech sciences This article is a position paper in favor of the establishment of a theoretical and practical framework to bring out an empirical science of speech, based on the contribution of all the sciences whose object of study is the speech. Central to this re-convergence …...

_________________________________________________________________________________________________________ Multimodal Prosody. The auction chant in the United States This paper proposes a multimodal prosodic analysis of the auction chant that is practiced in the US. Drawing upon a corpus that involves 6 auctioneers and relying upon the prosodic analysis of the chant by Kuiper, K. & Tillis F. …...

Toward an acoustic to articulatory inversion of a foreign speaker We present an extension of our acoustic-to-articulatory inversion method, based on unsupervised Hidden Markov Models. The articulatory vectors’ generation is based on the “GMM” approach. Considering the application of our method to the teaching of foreing languages, we study the …...

_________________________________________________________________________________________________________ Are female and male voices processed equally fast? This study deals with processing time of female and male speech. Several authors showed that vowel identification was more difficult on voices with a high F0 (Ryalls & Lieberman, 1982). Does this have consequences on word processing? Are female voices processed …...

Emotions detection in the voice of patients interacting with an animated conversational agent The French ARMEN ANR-funded project aims at building an assistive robot for elderly and disabled people We focus in this paper on the emotion detection module for this robot. The interaction is almost entirely conducted in a …...

_________________________________________________________________________________________________________ Formant analysis of French oral vowels in isolation: in search of a reference for learners of French as a Foreign Language This study focuses on the formant analysis of the 10 oral vowels in French: /i e ɛ a ɔ o u y ø œ/, pronounced in isolation but …...

_________________________________________________________________________________________________________ VisArtico : visualizing articulatory data acquired by an articulograph In this paper, we present VisArtico, visualization software of articulatory data acquired by an articulograph, AG500. The software allows displaying the positions of the sensors that are simultaneously played with the speech signal. It is possible to display the tongue …...

_________________________________________________________________________________________________________ Acoustic analysis of atypical contrasts in Northern-Irish English This paper participates in the discussion about the problematic status of the so-called “derived contrasts”. Our study consists in an acoustic analysis of two vowel contrasts in Northern-Irish English. The first one arises from the Ulster variant of the Aitken law …...

Influence of the cheeks expansion during bilabial plosive production This experimental study highlights the influence of expansion of the cheeks during the pro- duction of bilabial plosives. The closure of the lips, before the plosive, causes an increase in intra-oral pressure. The assumption suggested in this paper is that the …...

_________________________________________________________________________________________________________ An Acoustic Study of Sustained Vowels produced by Patient with or without Unilateral Paralysis after thyroid Surgery. The present acoustic study is based on analyses of some spectral characteristics of the voice of patients with recurrent paralyses, and also of patients without diagnosed paralyses but with alteration of their …...

New approach for speaker clustering of broadcast news In this paper, we propose a new clustering model for speaker diarization. A major problem with using greedy agglomerative hierarchical clustering for speaker diarization is that they do not guarantee an optimal solution. We propose a new clustering model, by redefining clustering …...

_________________________________________________________________________________________________________ Rhoticity and derhoticisation in Ayrshire Scottish English Scottish English is typically described as a rhotic variety, whose rhotic variants are taps [ɾ] and approximants [ɹ] (Wells, 1982 : 411). Non-prevocalically, recent findings indicate not only that /r/ is extremely variable, but also that a process of derhoticisation might be …...
