PROBLEM TO BE SOLVED: To allow prosody to be easily edited.SOLUTION: A prosody editing apparatus includes a first selection section, a storage section, a search section, a normalization section, a mapping section, a display section, a second selection section, a restoration section and a replacement section. The storage section associates and stores attribute information indicating an attribute related to a phrase and one or more prosodic patterns in which parameters for indicating a type of prosody of the phrase and representing the prosody of the phrase include an element number not less than a phoneme number of the phrase. The search section searches the storage section for one or more prosodic patterns in which a selection phrase and the attribute information coincide with each other and obtains a prosodic pattern set. The mapping section individually maps the prosodic patterns normalized into a low-dimensional space represented by coordinates having a number less than the element number and generates mapping coordinates. The restoration section restores the prosodic patterns according to selection coordinates and obtains restoration prosodic patterns. The replacement section replaces prosody of synthesis speech generated on the basis of the selection phrase with the restoration prosodic patterns. |
