Abstract
A speech acquisition unit 1 acquires an original speech uttered freely by a user. A speech data processing unit 7 processes an original speech signal to generate a processed speech signal. An acoustic model switching unit 4 determines one acoustic model from among a plurality of acoustic models 3-1 to 3-x, based on a recognition score for each languagein which a speech recognition unit 5 performs a recognition process on time series data on an acoustic feature of the processed speech signal to be calculated by using the acoustic models 3-1 to 3-x for individual languages.
