Abstract

um método para processar sinais de fala antes de encriptar um sinal digital compreendendo dados de áudio inclui selecionar codificação de domínio de frequência ou codificação de domínio de tempo com base em uma taxa de bits de codificação a ser usada para codificar o sinal digital e uma detecção de latência de passo curto do sinal digital.
