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

A method for editing speech synthesis, comprising:

• analyzing a text;
• acquiring a phonemic and prosodic information to synthesize a speech corresponding to the text;
• editing at least a part of the phonemic and prosodic information;
• converting the phonemic and prosodic information before editing the part to a first speech waveform;
• converting the phonemic and prosodic information after editing the part to a second speech waveform;
• calculating a contrast period of the first speech waveform and the second speech waveform respectively, the contrast period corresponding to the part in the phonemic and prosodic information;
• and
• generating an output waveform by connecting a first partial waveform and a second partial waveform, the first partial waveform containing the contrast period of the first speech waveform, the second partial waveform containing the contrast period of the second speech waveform.

A computer readable medium for causing a computer to perform a method for editing speech synthesis, the method comprising:

• analyzing a text;
• acquiring a phonemic and prosodic information to synthesize a speech corresponding to the text;
• editing at least a part of the phonemic and prosodic information;
• converting the phonemic and prosodic information before editing the part to a first speech waveform;
• converting the phonemic and prosodic information after editing the part to a second speech waveform;
• calculating a contrast period of the first speech waveform and the second speech waveform respectively, the contrast period corresponding to the part in the phonemic and prosodic information;
• and
• generating an output waveform by connecting a first, partial waveform and a second partial waveform, the first partial waveform containing the contrast period of the first speech waveform, the second partial waveform containing the contrast period of the second speech waveform.
