PURPOSE The purpose of this study was to further explore the understanding of speaker-specific realizations of the /s/-/ʃ/ contrast in German in relation to individual differences in palate shape. METHOD Two articulatory experiments were carried out with German native speakers. In the first experiment, 4 monozygotic and 2 dizygotic twin pairs were(More)
The purpose of this study is to examine and compare the amount of inter-speaker variability in the articulation of monozygotic twin pairs (MZ), dizygotic twin pairs (DZ), and pairs of unrelated twins with the goal of examining in greater depth the influence of physiology on articulation. Physiological parameters are assumed to be very similar in MZ twin(More)
Purpose Mumbling as opposed to clear speech is a typical male characteristic in speech and can be the consequence of a small jaw opening. Whereas behavioral reasons have often been offered to explain sex-specific differences with respect to clear speech, the purpose of this study is to investigate a potential anatomical reason for smaller jaw openings in(More)
German speakers receive different ratings in their perceived vocal attractiveness and personality characteristics. An experiment was conducted to evaluate the perceived personality attributions of 32 German listeners and find acoustic cues that correlate to these attributions. The attributed opposition pairs on which the speakers were judged were reduced by(More)

Six forms of cytochrome P-450 in the mitochondria of larvae from Musca domestica were isolated by solubilization with CHAPS followed by ammonium sulfate fractionation and HPLC on an anion-exchange column. Forms 1, 2, 3, 5, and 6 catalyzed the formation of 20-hydroxy-ecdysone from ecdysone in the presence of NADPH and pig adrenal adrenodoxin and adrenodoxin(More)
The purpose of this study is to investigate the potential relationship between speaking fundamental frequency and acoustic vowel space size, thus testing a possible perceptual source of sex-specific differences in acoustic vowel space size based on the greater inter-harmonic spacing and a poorer definition of the spectral envelope of higher pitched voices.(More)
Young multi-ethnolectal speakers of Hamburg-German introduced an alternation of /ç/ to [ʃ] following a lax front vowel /ɪ/ [1]. We conducted perception studies exploiting this contrast in Berlin (Germany), a city with large multi-ethnic neighborhoods. This alternation is pervasive and noticeable, it is mocked and stigmatized and there is an awareness that(More)
