Abstract
A waveform memory that stores a plurality of speech unit waveforms corresponding to respective speech units, wherein an address order of the speech unit waveforms is determined by a sort order of speech units included in a speech unit sequence corresponding to a phoneme sequence of training data, and the speech units included in the speech unit sequence are selected so as to synthesize a speech of the phone sequence.

27. A method for storing a plurality of speech unit waveforms corresponding to respective speech units into a waveform memory, comprising:
-
inputting a speech unit sequence corresponding to a phoneme sequence of training data; counting a frequency of a combination of two speech units continuously appearing in the speech unit sequence; selecting the combination of two speech units in higher order of the frequency; and adjacently storing two speech unit waveforms corresponding to the combination into the waveform memory.

28. A non-transitory computer readable memory storing program instructions, which when executed by a computer, results in performance of a method for storing a plurality of speech unit waveforms corresponding to respective speech units into a waveform memory, comprising steps of:
-
inputting a speech unit sequence corresponding to a phoneme sequence of training data; counting a frequency of a combination of two speech units continuously appearing in the speech unit sequence; selecting the combination of two speech units in higher order of the frequency; and adjacently storing two speech unit waveforms corresponding to the combination into the waveform memory.
