“…There has been rich empirical evidence that in many languages focus is realized mainly by increasing the pitch range, intensity, duration, and articulatory fullness of the focused word, and reducing the F 0 and intensity of the following words, while leaving the prefocus words largely unchanged (English: Cooper et al, 1985;de Jong, 1995;Xu and Xu, 2005;Mandarin: Chen and Gussenhoven, 2008;Xu, 1999;German: Féry and Kügler, 2008;Greek: Botinis et al, 1999;Dutch: Swerts et al, 2002;Japanese: Ishihara, 2002; Korean: Lee and Xu, 2010;Turkish: Ipek, 2011;Tibetan: Wang et al, 2012;Zhang et al, 2012;Estonian: Sahkai et al, 2013). The reduction of postfocus F 0 and intensity is known as postfocus compression or PFC , and it is found to be critical for focus perception in at least some of these languages (Vainio et al, 2003, for Finnish;Rump and Collier, 1996, for Dutch;Prom-on et al, 2009, for English;Ishihara, 2011, andSugahara, 2005, for Japanese; Xu, 2005, andXu et al, 2012, for Mandarin). What is yet unclear, and in fact rarely asked, is how extensive the temporal domain of PFC is.…”
