| 20110046957 | SYSTEM AND METHOD FOR SPEECH SYNTHESIS USING FREQUENCY SPLICING - Techniques are disclosed for frequency splicing in which speech segments used in the creation of a final speech waveform are constructed, at least in part, by combining (e.g., summing) a small number (e.g., two) of component speech segments that overlap substantially, or entirely, in time but have spectral energy that occupies disjoint, or substantially disjoint, frequency ranges. The component speech segments may be derived from speech segments produced by different speakers or from different speech segments produced by the same speaker. Depending on the embodiment, frequency splicing may supplement rule-based, concatenative, hybrid, or limited-vocabulary speech synthesis systems to provide various advantages. | 02-24-2011 |
