“…An example of the former would be studies looking at the scaling of tones in the phonetic realization of intonation, where a central issue is how to capture tonal invariance in the face of variation in pitch range (e.g., Dilley and Brown, 2007;Hirschberg and Ward, 1992;Liberman and Pierrehumbert, 1984). Examples of the latter include clinical studies investigating the extent to which various clinical populations have atypical prosody (e.g., Diehl, Watson, Bennetto, Mcdonough, and Gunlogson, 2009;Hubbard and Trauner, 2007), studies of the vocal correlates of affect (e.g., Banse and Scherer, 1996;Ladd, Silverman, Tolkmitt, Bergmann, and Scherer, 1985;Sobin and Alpert, 1999), and studies of various speaker-oriented factors such as the effects of age, gender, height and weight, ethnicity, and regional accent on f0 (Chen, 2005;Deutsch, Le, Shen, and Henthorn, 2009;Hollien, Hollien, and de Jong, 1997;Nishio and Niimi, 2008;Van Bezooijen, 1995;Van Dommelen and Moxness, 1995).…”
