Abstract	:	One requirement for researching and building spoken language systems is the availabilityof speech data that have been labeled and time-aligned at the phonetic level. Althoughmanual phonetic alignment is considered more accurate than automatic methods, it is tootime consuming to be commonly used for aligning large corpora. One reason for the greateraccuracy of human labeling is that humans are better able to locate distinct events in thespeech signal that correspond to specific phonetic characteristics. The development of theproposed method was motivated by the belief that if an automatic alignment method wereto use such acoustic-phonetic information, its accuracy would become closer to that of hu-man performance. Our hypothesis is t hat t he integration of acoustic-phonetic informat ioninto a stateof-the-art automatic phonetic alignment system will significantly improve itsaccuracy and robustness.In developing an alignment system that uses acoustic-phonetic information, we use ameasure of intensity discrimination in detecting voicing, glottalization, and burst-relatedimpulses. We propose and implement a method of voicing determination that has av-erage accuracy of 97.25 (which is an average 58 reduction in error over a baseline....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
