Acoustics V-1 An acoustic study of north Welsh voiceless fricatives

  Welsh, a Celtic language spoken in Wales, is unusual amongst the languages of the world in having a minimum of 8 fricative contrasts at (at least) 6 places of articulation, a relatively large number. Most research on fricatives has been conducted on languages with a relatively small (but cross-linguistically common) number of fricative place contrasts. Welsh fricatives have not previously been the subject of a detailed acoustic study across speakers. This study begins to fill that gap, and also provides some phonetic information on how one language organises a large system of fricative place contrasts.

  Modern articulatory speech synthesizers simulate the human speech production system in an increasingly accurate manner. In this direction, we relax the simplifying assumption of zero mean flow velocity during speech production and we investigate potential effects. Further, we introduce a reduced parameter set for our 3D articulatory model which simplifies its control and does not allow humanly infeasible articulations. Vowel-Fricative-Vowel synthesis experiments using our twofold augmented synthesizer are reported.

Paper File
  At the beginning of the last century, the growing interest in foreign cultures and languages led to a rapid development of experimental phonetics. In Germany, Rousselot's scholar Panconcelli-Calzia introduced experimental phonetics as scientific field in Hamburg like Gutzmann and Wethlo did in Berlin. A number of historic instruments remembering these times are preserved in the Dresden University now. This paper gives a short overview of the development of the experimental phonetics in Hamburg and Berlin and the history of the phonetic collection in Dresden. In the main part, some projects concerning selected objects of the collection (Wethlo's cushion pipes, history of pitch measurement, mechanical voices from Kessel and Hoelbe) are summarized.
