Apparatus and method for editing speech synthesis, and computer readable medium

Abstract

An acquisition unit analyzes a text, and acquires phonemic and prosodic information. An editing unit edits a part of the phonemic and prosodic information. A speech synthesis unit converts the phonemic and prosodic information before editing the part to a first speech waveform, and converts the phonemic and prosodic information after editing the part to a second speech waveform. A period calculation unit calculates a contrast period corresponding to the part in the first speech waveform and the second speech waveform. A speech generation unit generates an output waveform by connecting a first partial waveform and a second partial waveform. The first partial waveform contains the contrast period of the first speech waveform. The second partial waveform contains the contrast period of the second speech waveform.
