This article deals with the Tashlhiyt dialect of Berber (henceforth TB) spoken in the southern part of Morocco. In TB, words may consist entirely of consonants without vowels and sometimes of only voiceless obstruents, e.g. tft#tstt "you rolled it (fem)". In this study we have carried out acoustic, video-endoscopic and phonological analyses to answer the following question: is schwa, which may function as syllabic, a segment at the level of phonetic representations in TB? Video-endoscopic films were made of one male native speaker of TB, producing a list of forms consisting entirely of voiceless obstruents. The same list was produced by 7 male native speakers of TB for the acoustic analysis. The phonological analysis is based on the behaviour of vowels with respect to the phonological rule of assibilation. This study shows the absence of schwa vowels in forms consisting of voiceless obstruents.
Data on lingual movement, dorsopalatal contact and F2 frequency presented in previous papers of ours (Recasens, 2002; Recasens and Pallarès, 2001; Recasens, Pallarès and Fontdevila, 1997) suggest that the degree of articulatory constraint (DAC) model accounts to a large extent for the extent and direction of tongue dorsum coarticulation in VCV and CC sequences. A goal of this investigation is to verify the predictions of this model with respect to jaw V-to-V effects in VCV sequences using articulatory movement data collected with electromagnetic articulometry (EMA).
In order to understand the functional morphology of the human voice producing system, we are in need of data on the vocal tract anatomy of other mammalian species. The larynges and vocal tracts of four species of Artiodactyla were investigated in combination with acoustic analyses of their respective calls. Different evolutionary specializations of laryngeal characters may lead to similar effects on sound production. In the investigated species, such specializations are: the elongation and mass increase of the vocal folds, the volume increase of the laryngeal vestibulum by an enlarged thyroid cartilage and the formation of laryngeal ventricles. Both the elongation of the vocal folds and the increase of the oscillating masses lower the fundamental frequency. The influence of an increased volume of the laryngeal vestibulum on sound production remains unclear. The anatomical and acoustic results are presented together with considerations about the habitats and the mating systems of the respective species.
The genetic code, the primary manifestation of life, and, on the other hand, language, the universal endowment of humanity and its momentous leap from genetics to civilization, are the two fundamental stores of information transmissible from the ancestry to the progeny, the molecular succession, which ensures the transfer of hereditary messages from the cells of one generation to the next generation, and the verbal legacy as a necessary prerequisite of cultural tradition. Divergent terminologies direct attention to different pattemings; and finding a logically convincing test, acceptable all around, that can determine whether one such system of terms is superior to its rivals, is often impossible. Yet the slow processes of evolution presumably apply to human societies and their symbolic systems as much as to human bodies, so that when logic cannot decide, survival eventually will.
Metaphern bestimmen nicht nur unser alltägliches Leben, etwa wenn wir vom Rad der Geschichte oder der Bühne des Lebens sprechen, sie geben auch nützliche Orientierung in vielen Bereichen der Wissenschaft, von den schwarzen Löchern der Physiker bis zur Computermetapher des Gehirns in der Kognitionswissenschaft. Eine solche Metapher ist auch die Deutung der Sprache als Werkzeug.
