PROBLEM TO BE SOLVED: To artificially increase the number of representative speakers, decrease the number of representative speakers which are stores, and save the storage capacity by generating the speaker partial space moving vector of an interpolation speaker from the speaker partial space moving vector of a representative speaker. SOLUTION: A speaker partial space moving vector generation part 9 for the interpolation speaker is connected to a speaker adaptation part 4 and a model-after-adaptation generation part 7. An interpolation speaker candidate selection part 9a generates all combinations of P speakers from the speaker partial space moving vectors of N representative speakers stored in a speaker partial space moving vector storage part 6 for representative speakers. And, speaker partial space moving vector, weight, a mean vector, a transition probability, and a variance vector of the representative speaker corresponding to the combinations are sent out to a speaker partial space moving vector calculation part 9b for te interpolation speaker. The calculation part 9b calculates the speaker partial space moving vector of the interpolation speaker by using the sent speaker partial space moving vector for the interpolation speaker. |
