ENProblems of pitch evaluations from pitch tracks obtained from computer aided acoustical analysis are considered; case of monophonic vocal performance is examined. The importance of limited jnd on the adequate desirable precision of the evaluation is noted. Three methods of pitch evaluations were applied. First, pitches of one Lithuanian traditional vocal solo performance (six melostrophes) were independently evaluated manually from Praat-aided logf0 tracks by three subjects. From these data on individual pitches, evaluations of musical scales averaged across the entire performance were also derived. Second, the evaluations of musical scales were repeated based on logf0 histograms compiled from Praat readings. Third, software NoteView for automated pitch extraction and integral evaluation was applied. NoteView was chosen since it is considered one of the best programs for this purpose. Evaluations of individual pitches by the three subjects (1st method) differed by 6.5 cents (here and hereafter averaged values are presented). However, for the degrees of musical scale, the difference dropped to 1.6-3.4 cents, depending on the range of sound durations (IOIs) considered. In comparison, the other two methods gave considerably inferior results (deviations from the semi-manual evaluations of the musical scale): 6.0-10.0 cents for histograms (2nd method) and 3.9-7.9 cents for NoteView (3rd method). The semi-manual method of pitch evaluation, though time-consuming, is still more acceptable than the two automated methods considered; unless precision of 4.0-9.0 cents or worse is sufficient. The reasons (need for subjective decisions, e.g., on target pitch, etc.) are discussed. [From the publication]
