Abstract
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.
