A method for concatenating a series of electronic voice segments encoded according to a source modeled algorithm is provided. The source modeled algorithm includes an excitation function such as a pitch function. The method includes evaluating an excitation function of the segments to be concatenated. The method further includes combining the segments into a sequence. The method further includes altering the excitation function such that the decoded sequence more accurately represents human speech. The alteration may include adjusting the pitch excitation function across one or more concatenation points. The alteration may also include adjusting the pitch excitation function across the sequence to more accurately reflect the content of the sequence. The source modeled algorithm may be a linear predictive algorithm such as Code Excited Linear Prediction (CELP) or Linear Predictive Coding (LCP). A system for concatenating a series of electronic voice segments is also provided.
A method of concatenating a plurality of electronic voice data segments, the plurality of segments being encoded according to a source modeled algorithm, the algorithm including at least one excitation function, wherein each data segment includes information relating to an excitation function and wherein at least one excitation function is usable within a Code Excited Linear Prediction system to synthesize voice, the method comprising:
A system for producing a sequence of concatenated electronic voice data segments, comprising:
