A system and method generate synthesized speech through concatenation of speech segments that are derived from a large prosodically-rich corpus of speech segments including using an additional dictionary of speech segment identifier sequences.

Corpus-based speech synthesis based on segment recombination

The excitation in a CELP-like speech coder is recursively calculated. For a given bitrate and a given complexity, the recursive approach described lowers the complexity with minimum impact on speech quality. The excitation signal is a sum of at least three vector terms, each vector term being a product of a codebook vector z and an associated gain term g . A first vector term g z is determined that is representative of a target excitation vector x. Each remaining vector term is recursively determined as a vector term g z representative of the difference between the target excitation vector x and the sum of previously determined vector terms,
