Abstract
A voice recognition deviceincludes: a phonological awareness feature amount extraction unitthat transforms an acoustic feature amount sequence of input voice into a phonological awareness feature amount sequence for the languageusing a first model parameter group; a phonological awareness feature amount extraction unitthat transforms the acoustic feature amount sequence of the input voice into a phonological awareness feature amount sequence for the languageusing a second model parameter group; a phonological recognition unitthat generates a posterior probability sequence from the acoustic feature amount sequence of the input voice, the phonological awareness feature amount sequence for the language, and the phonological awareness feature amount sequence for the languageusing a third model parameter group; and a voice text transformation unitthat performs voice recognition based on the posterior probability sequence to output text of a voice recognition result.
