Abstract
IIDENTIFICAçãO E EXCLUSãO DE QUADROS DE PAUSA PARA ARMAZENAMENTO, TRANSMISSãO E REPRODUçãO DE FALA" A invenção é direcionada a técnicas de armazenamento em buffer, transmissão e reprodução de voz condensada. As técnicas podem envolver identificação de quadros de voz codificados como fala ou uma pausa e exclusão seletiva de uma parte dos quadros para armazenamento, transmissão ou reprodução com base na identificação. Desta maneira, as técnicas são capazes de condensar uma série de quadros de voz codificados. Quando codificação à taxa variável é empregada, um quadro de pausa pode ser identificado, por exemplo, com base em uma comparação de limite para a taxa do quadro codificado. Em alguns casos, as técnicas podem envolver exclusão de apenas uma parte dos quadros identificados de uma seqüência consecutiva dos quadros identificados, preservando, assim, um número mínimo dos quadros identificados necessários para conversação inteligível.
