Abstract:
[Object] An object is to provide a speech recognition device with improved recognition accuracy using characteristics of a neural network. [Solution] A speech recognition device includes: an acoustic model  308  implemented by a RNN (recurrent neural network) for calculating, for each state sequence, the posterior probability of a state sequence in response to an observed sequence consisting of prescribed speech features obtained from a speech; a WFST  320  based on S −1 HCLG calculating, for each word sequence, posterior probability of a word sequence in response to a state sequence; and a hypothesis selecting unit  322 , performing speech recognition of the speech signal based on a score calculated for each hypothesis of a word sequence corresponding to the speech signal, using the posterior probabilities calculated by the acoustic model  308  and the WFST  320  for the input observed sequence.

Claim (Index 4):
The speech recognition device according to  claim 1 , wherein\n the first posterior probability calculating means includes a neural network responsive to an input of the observed sequence pre-configured to calculate posterior probabilities of states that generate the observed sequence, and first probability calculating means for calculating probability of occurrence of the state sequence, based on the sequence of posterior probabilities calculated by the neural network.
