Abstract
Spread level parameter correcting means 501 receives a contour parameter as information representing the contour of a feature sequence (a sequence of features of a signal considered as the object of generation) and a spread level parameter as information representing the level of a spread of the distribution of the features in the feature sequence. The spread level parameter correcting means 501 corrects the spread level parameter based on a variation of the contour parameter represented by a sequence of the contour parameters. Feature sequence generating means 502 generates the feature sequence based on the contour parameters and the corrected spread level parameters.
Claims19
A feature sequence generating device comprising:
- a spread level parameter correcting unit which receives a contour parameter which represents the contour of a feature sequence of a signal and a spread level parameter which represents the level of a spread of the distribution of the features in the feature sequence, and corrects the spread level parameter based on a variation of the contour parameter represented by a sequence of the contour parameters;
- and
- a feature sequence generating unit which generates the feature sequence based on the contour parameters and the spread level parameters corrected by the spread level parameter correcting unit.
A feature sequence generating method comprising:
- correcting a spread level parameter representing the level of a spread of the distribution of features in a feature sequence of a signal, based on the variation of a contour parameter, which represents a contour of the feature sequence, represented by a contour parameter sequence;
- and
- generating the feature sequence based on the contour parameters and the corrected spread level parameters.
A feature sequence generating program for causing a computer to execute:
- a process of correcting a spread level parameter representing the level of a spread of the distribution of features in a feature sequence of a signal, based on the variation of a contour parameter, which represents a contour of the feature sequence, represented by a contour parameter sequence;
- and
- a process of generating the feature sequence based on the contour parameters and the corrected spread level parameters.
