    The aim of this study is to analyse the steady--state portion of the first two formants (F1) and (F2) in the production of [CV] sequences, containing vowels [i, a, u], pronounced in two speech rates (normal and fast), by groups of untreated and treated stutterers, and control subjects. Locus equations have been calculated to observe for potential differences in coarticulatory strategies between the three groups. Data analyses reveal a reduction of vowel space for stutterers at a normal speaking rate. When speech rate increases, no reduction of vowel space is noticeable for the latter group of speakers, contrary to treated stutterers and controls. No significant differences between the three groups have been observed in coarticulatory strategies

    Articulatory copy synthesis from cine X-ray films

    International audienceThis paper deals with articulatory copy synthesis from X-ray films. The underlying articulatory synthesizer uses an aerodynamic and an acoustic simulation using target area functions, F0 and transition patterns from one area function to the next as input data. The articulators, tongue in particular, have been delineated by hand or semi-automatically from the X-ray films. A specific attention has been paid on the determination of the centerline of the vocal tract from the image and on the coordination between glottal area and vocal tract constrictions since both aspects strongly impact on the acoustics. Experiments show that good quality speech can be resynthesized even if the interval between two images is 40\,ms. The same approach could be easily applied to cine MRI data

    International audienceArticulatory-acoustics events and the relations that tie them together are crucial to allowing for the proper speech functioning. The features at the phonological level and the cues studied in phonetics are related to specific speech events, visible for example in acoustic signals. Thus, a close analysis of these events allows us to understand which relations underpin the system of oppositions. This article deals with the Alsatian stops, taking into account he feature [voice]. A number of questions relating to the nature of the plosives are not solved. These questions are representative of the difficulties in analyzing a system of fragile oppositions which nevertheless is operational and fluent. So, we shall thus present a classification of the consonants of Alsatian. We shall begin by evoking problems posed by the classification of plosives, through features and cues. We shall use the results obtained during experimental analyses of the speakers of Colmar, the results of which might demonstrate the importance of understanding the event structure of these consonants, in order to classify them at a convincing phonological level. Les consonnes de l'alsacien, en l'occurrence la variante dialectale parlée dans la région de Colmar, comportent deux séries de consonnes occlusives. Contraire-ment aux deux séries de consonnes correspondantes en français (p/t/k et b/d/g), en alsacien, aucune des séries ne présente le trait de sonorité. Lors de leur production, les cordes vocales ne vibrent pour aucun des deux groupes. Cependant, ces sons sont graphiés de deux maniÚres différentes, premier indice qui signale que les lo-cuteurs font une différence entre eux.

    Les occlusives de l'alsacien : une Ă©tude temporelle

    International audienceABSTRACT _____________________________________________________________________ This article deals with Alsatian plosives, and French plosives as pronounced in French by Alsatian speakers. Results are based on data from 3 Alsatian female speakers, who also speak French. They were recorded in their native language, Alsatian. The corpus includes all Alsatian stops (which are written b d g and p t k, like in French). Analyses of the data show that there are no voiced stops in Alsatian, and that despite absence of the voiced / voiceless contrast, these stops may be phonological.. Hence, the distinction between the series is based on various cues, such as intra-segmental phases, and especially the duration of the acoustic silent phase.RESUME _______________________________________________________________________ Cet article traite des consonnes occlusives de l'alsacien. Les rĂ©sultats prĂ©sentĂ©s proviennent des enregistrements de trois locutrices de l'alsacien, Ă©galement francophones. Elles ont Ă©tĂ© enregistrĂ©es dans leur langue maternelle, l'alsacien. Le corpus d'Ă©tude comprends toutes les consonnes occlusives de l'alsacien (transcrites Ă  l'Ă©crit comme en français : p t k et b d g). L'analyse de ces enregistrements montre d'une part que les deux sĂ©ries de consonnes occlusives de l'alsacien ne sont jamais sonores, mais que leur distribution correspond Ă  celles de paires minimales oppositives. La distinction entre les deux sĂ©ries repose donc sur d'autres indices, tels que les durĂ©es intra-segmentales, notamment les durĂ©es des silences au sein mĂȘme des deux sĂ©ries de consonnes

    Produire des occlusives : gestion temporelle en alsacien et en français parlé en Alsace.

    International audienceProduire des occlusives en alsacien et en français implique une gestion temporelle trĂšs diffĂ©rente. L’alsacien demande une consĂ©cutivitĂ© de gestes, les intervalles seuls entre ces Ă©vĂšnements permettant de distinguer deux catĂ©gories. Si le français suppose une gestion de ce type pour produire ses occlusives sourdes, les sonores requiĂšrent une vibration des cordes vocales et une occlusion buccale simultanĂ©es. La difficultĂ© pour les dialectophones d’Alsace en français concerne donc spĂ©cifiquement les occlusives sonores. Cependant, la gestion temporelle n’est pas simplement plaquĂ©e d’une langue sur l’autre par ces locuteurs : le systĂšme se rĂ©organise, et tente d’accĂ©der aux zones de viabilitĂ©s attendues

    Languages in contact: the case of Alsatian and French

    International audienceFeatures and cues are not as rigid as we might think. Some articulatory targets are clearly sufficient to ensure mutual understanding.-The question raised by these changes is that of the nature of phonological systems and their phonetic basis.-It seems feasible to suggest a more flexible reading of the phonetic system, based on variability and adaptation that arise within a group of different phonemes as part of language contact

    Organisation temporelle et analyses acoustiques des occlusives du persan (locuteurs de Téhéran)

    Notre Ă©tude porte principalement sur l'organisation temporelle de la production des occlusives du persan, complĂ©tĂ©e par une analyse spectrale. Cette investigation a montrĂ© que le trait phonologique de sonoritĂ© peut ĂȘtre gĂ©rĂ©e par des diffĂ©rences d organisation temporelle ou de timing acoustique des consonnes cibles. L augmentation de la vitesse d Ă©locution a indiquĂ© que le maintien de l opposition de sonoritĂ© dans cette langue est robuste. Une analyse spectrale a rĂ©vĂ©lĂ© quelques caractĂ©ristiques acoustiques qui semblent ĂȘtre spĂ©cifiques aux occlusives du persan. En effet, la prĂ©sence significative de vibrations laryngĂ©es, Ă  faibles amplitudes, dans la phase de la tenue consonantique des non-voisĂ©es, ainsi que l apparition irrĂ©guliĂšre d aspiration, dans la phase de l explosion des non-voisĂ©es sont assez inhabituelles. L analyse spectrale des consonnes rares, [/] et [q], a montrĂ© qu elles ont des rĂ©alisations variables, en ce qui concerne leur mode de production.STRASBOURG-B.N.U.S. (674821001) / SudocSudocFranceF
