Abstract

"SISTEMA DE CODIFICAçãO, E, PROCESSO PARA CODIFICAR UM SINAL DE FALA". Um sistema e processo de codificação de fala para codificar um sinal de dados de fala incluindo um número de quadros. O sistema de codificação de fala inclui um determinador de taxa de dados de fala e um número de codificadores de sinal de dados de fala. O determinador de taxa de dados de fala determina a taxa de dados de cada um dos quadros e seleciona um dos codificadores de sinal de dados de fala baseado em cada taxa de dados. Cada quadro pode ser codificado usando um processo ou padrão de codificação diferente. O sistema de codificação pode adicionalmente incluir um controlador de rede para selecionar qualquer número dos codificadores de sinal de dados de fala com base em fatores pré-determinados.
