These filesare text files with a number of columns; thefirst contains the rule names, and the followingcomprise three pairs of values, correspondingto the timing and F 0 of the critical pitch pointsof the rules. The three points are called ini (initial),mid (medial), and fin (final). Each pointcontains values for timing (T) and F 0 (F0).Timing is expressed as a percentage into thestressed syllable, starting from the onset of thestressed vowel. Three values are used for F 0 : L(low), H (high) and H+ (extra high, used in focalaccents). The pitch points are optional; theycan be left out if they are not needed by a rule.New rules can easily be added and existingones adjusted by editing the rule file. Table 2shows an example of the rules for compoundwords in Gotland, Dala-Bergslagen and UpperDalarna Swedish. Several rules contain an extrapitch gesture in the following (unstressed) segmentof the annotated input speech sample.This extra part has the word ‘next’ attached toits rule name; see e.g. cpa2 in Table 2.Table 2.
