Abstract

"MéTODO E APARELHO PARA A RECONSTRUçãO DA FALA EM UM SISTEMA DE RECONHECIMENTO DE FALA DISTRIBUìDO". Em um sistema de reconhecimento de fala distribuído (20) que compreende um primeiro dispositivo de comunicação (22) que recebe uma entrada de fala (34), codifica dados representativos da entrada de fala (36, 38), e transmite os dados codificados (42) e um segundo dispositivo de comunicação localizado remotamente (26) que recebe os dados codificados (44) e compara os dados codificados com um conjunto de dados conhecido, o segundo dispositivo (26) incluindo um processador (92) com um programa que controla o processador (92) para operar de acordo com um método de reconstrução da entrada de fala incluindo a etapa (44) de receber dados codificados incluindo dados espectrais codificados e dados de energia codificados. O método inclui ainda a etapa (46, 48) de decodificar os dados espectrais codificados e os dados de energia codificados para determinar os dados espectrais e os dados de energia. O método também inclui a etapa (50, 52) de combinar os dados espectrais e os dados de energia para reconstruir a entrada de fala.
