Christian Gulli: Method for voice analysis and synthesis using wavelets. Sextant Avionique, Oblon Spivak McClelland Maier & Neustadt P C, October 20, 1998: US05826232 (9 worldwide citation)

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 algorit ...
