This study examines possible differences between the acoustic realization of the intersibilant contrast /s/~/ʃ/ in German and American English. A range of acoustic parameters (COG, standard deviation, skewness, kurtosis and Discrete Cosine Transformation coefficients) are calculated to characterize the spectra of the two sibilants. Significant differences(More)
In Berlin German, the identification of /ç/ as in Fichte ‘spruce’ versus the alveopalatal fricative /ʃ/ in fischte (3. sg. past tense) ‘to fish’ is influenced by what neighborhood in Berlin hearers believe a speaker comes from (KB: Kreuzberg: multi-ethnic, multi-cultural or ZD: Zehlendorf: mono-ethnic, upscale, affluent area) and the inferences made as to(More)
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)
We conducted an AX-discrimination task to test for differences in perceived auditory similarity in monozygotic (MZ) and dizygotic (DZ) twin pairs and unrelated speakers. In addition, we performed acoustic analyses to find acoustic correlates that explain the differences in perceived similarity. Results indicate that unrelated speakers are significantly(More)
[2] postulates that the multi-ethnolect Hood German (as spoken in Berlin, Ger) differentiates three realizations of /ç/: [ç], [ɕ] and [∫]. Earlier acoustic analyses of 1192 tokens of /ç/ from the ZASspontaneous speech database (collected from 9 adolescent speakers of the Hood German multiethnolect) [9] showed no reliable differences in curtosis, skewness,(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)
