Abstract

<B>MéTODO E SISTEMA PARA CONTROLAR A CODIFICAçãO DE FALA EM UM SISTEMA DE COMUNICAçãO<D> Um método e um sistema para controlar a codificação de fala em um sistema de comunicação utilizam informações de realimentação como dados de controle de modificação de pacote (154) enviados de um controlador de saída de ligação de comunicação, como um árbitro de rede (142). O árbitro de rede (142) envia os dados de controle de modificação de pacote (154) para um "vocoder" selecionado (146) para mudar os estados de filtro do ''vocoder'' selecionado (146) quando o árbitro de rede (142) modifica um pacote de fala de saída comunicado de uma ligação de comunicação (20) para facilitar a convergência aperfeiçoada de um codificador de fala e um decodificador de fala, tal como uma unidade de assinante móvel.
