Introduction to DVD maps
Previous Top Next

The online analysis of vocalization and the automatic generation of the syllable table is the corner stone of SA+, and one of the most useful descriptive model of such tables is displaying dynamic vocal development (DVD) maps, showing vocal changes as movies. You should keep in mind, however, that segmentation of sound to syllable units is a double-edge sword: it can uncover song structure if properly used, but it might also inappropriately chop the sound into inappropriate units. This is not only because the criteria for segmenting sounds are not always robust, but mainly because the deep structure of vocalization bout is not trivially related to syllable units. The binary feature files that are automatically created during the live analysis keep record of non segmented (continuous) feature curves. SA+ does not provide a means of explicitly analyzing these data, but you can easily export them to Matlab.
