Abstract

Patente de Invenção:<B>"APARELHO DE CODIFICAçãO DE DIáLOGO DE MODO MúLTIPLO E APARELHO DE DECODIFICAçãO"<D>. A informação de excitação é codificada no modo múltiplo usando-se as características estática e dinâmica de parâmetros de trato vocal quantificados, e também em um lado de decodificador, o pós-processamento é realizado no modo múltiplo, desse modo melhorando-se as qualidades de uma região de diálogo não de voz e de uma região de ruído estacionário.
