Abstract
The voice synthesis of the invention analyzes a voice signal by orthogonal breakdown on a basis of wavelets with compact support, preferably Daubechies wavelets. The synthesis is carried out on the basis of coefficients which are stored and selected during the analysis, according to the same algorithm as that used for the analysis.
