The Use of Syllable Segmentation Information in Continuous Speech Recognition Hybrid Systems Applied to the Portuguese Language

摘要

Recent works have showed that the use of syllables as the basic unit in a speech recognition system could be very useful. These works introduced mehtods exploiting syllable information as a mean to add robustness in "traditional" systems that use phonemes/phones as the basic unit. Being the Portuguese a highly syllabic language we expected that information from syllables would introduce potential benefits in speech recognition tasks. Following these ideas we started by developing differnet mehtods of automatic syllable segmentation. Next we applied the best segmentation method to our large vocabulary continuous speech corpus (BD-PUBLICO) achieving an accuracy of 72
