摘要：This paper analysed intonation in orders and petitions in Chilean Spanish through acompletely automated algorithm programmed in Matlab, which works withintonation phonetic features without analysing it phonologically. The results showthat three features allow to characterize the intonation of orders and petitions:duration, semitones range and a sequence of tonal movements. Duration inpetitions is larger than in orders, the range in semitones is larger in orders than inpetitions and orders more often present an affirmative pattern. Contrastively,petitions present a curve that begins with a fall and ends with a steady curve. Thealgorithm and the results can be used to, for example, create didactic material toteach intonation.
