The effect of palatalization on the articulatory and acoustic realization of Bulgarian plosives is well described. It has been shown in cross-splicing experiments that human listeners are more strongly influenced by the transition than by the burst. In two sets of experiments, palatalization in Bulgarian plosives is investigated in an automatic speech recognition setting. The confusions between phonemes in a plosive identification experiment show that palatalized consonants can be identified well on the basis of closure and burst alone. The addition of vowel transitions leads to a greater improvement in the identification rate for non-palatalized than for palatalized consonants. Follow-up experiments using quasi-cross-splicing indicate that the information carried by the transitions is more important than the information in the closure plus burst for both non-palatalized and palatalized plosives.
