To provide an interpolation data creating apparatus capable of creating data for articulatory parameter interpolation which reflects shape change of a speech organ by speech action, by simpler processing than transmissive imaging method.
The interpolation data creating apparatus of articulatory parameters for creating interpolation data when the articulatory parameters for synthesizing voice which continuously changes from a first phoneme to a second phoneme are created by interpolation between known articulatory parameters for synthesizing the first and the second phoneme includes: a change rate calculation means 60 for calculating transition of a change rate of a predetermined sound feature amount from the first phoneme to the second phoneme, from an input voice signal including the first phoneme and the second phoneme which are continuous; and an interpolation data creating means 64 for creating the interpolation data using the change rate.
