Kind Code:
A1
Abstract:
A speech recognition device (1) comprises: an output means (111) which, when speech data is inputted, uses a neural network (NN) for outputting a first probability (CP), which is the probability of a character sequence corresponding to a speech sequence expressed by the speech data, and a second probability (PP), which is the probability of a phoneme sequence corresponding to the speech sequence, to output a first probability and a second probability; and an update means which updates the first probability on the basis of the second probability and dictionary data (121) in which registered characters and registered phonemes that are the phonemes of the registered characters have been associated with each other.
