A cross-linguistic acoustic study of voiceless fricatives

Abstract: Results of an acoustic study of voiceless fricatives in seven languages are presented. Three measurements were taken: duration, center of gravity, and overall spectral shape. In addition, formant transitions from adjacent vowels were measured for a subset of the fricatives in certain languages. Fricatives were well differentiated in terms of overall spectral shape and their coarticulation effects on formant transitions for adjacent vowels. The center of gravity measurement also proved useful in differentiating… Show more

“…The method yields values for sibilants that can indeed be as low as 2000 Hz or as high as 8000 Hz or more. As can be seen from inspecting their spectra and reported spectral means, Gordon et al (2002) apparently used the incorrect method of Ladefoged (2003) (Navarro Tomás 1932: 105-107, Harris 1969. This is illustrated in Fig.…”

“…13 Erb. 8 Jongman et al (2000) report the values of 6133 and 4229 Hz respectively (for causes described in note 7 above, Gordon et al 2002 typically report differences of only 400 Hz between /s/ and /S/ for the languages they investigate). As noted above, measurement methods for spectral means have not yet been standardised and are therefore difficult to compare across sources.…”

“…Spectral moments have been widely used in the literature (Jassem 1979;Forrest et al 1988;Ladefoged 2003, 156ff;Gordon et al 2005;Machač-Skarnitzl 2005) to quantify consonantal -in particular fricativecharacteristics, especially with the need to distinguish one fricative from the other, across vowel context and speaker. 39 The first spectral moment, CoG (or "centroid"), is a measure for how high the frequencies in a spectrum are on average, it thus represents a spectral mean.…”
