Abstract
According to one embodiment, a speech synthesizer generates a speech segment sequence and synthesizes speech by connecting speech segments of the generated speech segment sequence. If a speech segment of a synthesized first speech segment sequence is different from the speech segment of a synthesized second speech segment sequence having the same synthesis unit as the first speech segment sequence, the speech synthesizer disables the speech segment of the first speech segment sequence that is different from the speech segment of the second speech segment sequence.
Claims7
A speech synthesizer, comprising:
- a generation unit that selects speech segments for respective synthesis units to generate a speech segment sequence, which is a sequence of the speech segments;
- a speech connection unit that synthesizes speech by connecting the speech segments of the speech segment sequence generated by the generation unit;
- a specifying unit that specifies a degraded region of a first previously synthesized speech segment sequence that is synthesized by the speech connection unit;
- and
- a prohibition unit that
- compares the first previously synthesized speech segment sequence with a second speech segment sequence having a same given synthesis unit as the first previously synthesized speech segment sequence, over the specified degraded region of the first previously synthesized speech segment sequence, and
- based on the comparison, disables a speech segment in the first speech segment sequence that is not included in the second speech segment sequence, during all subsequent selections of speech segments by the generation unit, for the given synthesis unit.
