Vocalization analysis tools

H. J. Fell, Joel MacAuslan

We offer two tools for automated vocalization analysis. The Syllable tool uses the Stevens landmark theory to find landmarks in vocalizations digitized as "wav" files. The landmarks are grouped to identify syllable-like productions in these vocalizations and the results are summarized. The Vocalization-Age tool is intended for pre-speech vocalizations. It uses the landmark and syllable information to yield a vocalization age that has been shown to clinically distinguish typically-developing children from children who are atrisk for later speech impairment.
