Title:
PHONEME DIVIDING DEVICE, METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2011013594
Kind Code:
A
Abstract:

To estimate phoneme boundary time more accurately than before.

A voice feature amount of input voice in each frame is extracted; a most likely phoneme is allocated for each frame, by using a statistic amount about voice feature amounts of a plurality of phonemes; when phonemes allocated in successive two frames are different, the phoneme boundary time is estimated, by setting either of the times included in a time range of the two frames, to the phoneme boundary time. It is determined whether the phoneme boundary time is reliable. The phoneme boundary time of the phoneme boundary in which it is determined that the phoneme boundary time is not reliable is estimated, by allocating the time in which a continuity length of each phoneme is larger, the larger the average becomes; and the larger it is expanded/contracted, the larger the variance becomes, for each phoneme which constitutes the phoneme boundary in which it is determined that the phoneme boundary time is not reliable.
