Abstract
método e sistema para dimensionar a ampliação de canais relevantes da fala em áudio de multicanais. a presente invenção refere-se a um método e sistema para filtragem um sinal multicanal de áudio tendo um canal de fala e pelo menos um canal sem fala, para melhorar a inteligibilidade de fala determinada pelo sinal. em modalidades típicas, o método inclui etapas de determinação de pelo menos um valor de controle de atenuação indicativo de uma medida de semelhança entre conteúdo da fala relacionada determinada pelo canal de fala e conteúdo da fala relacionada determinada pelo canal sem fala, e atenuando o canal sem fala em resposta a pelo menos um valor de controle de atenuação. tipicamente, a etapa atenuada inclui dimensionar um sinal de controle de atenuação bruto (por exemplo, um sinal de controle de ganho de ampliação) para o canal sem fala em resposta a pelo menos um valor de controle de atenuação. algumas modalidades são um processador programado de finalidade geral ou especial com software ou firmware e/ou de outra maneira configurado para realizar a filtragem de acordo a invenção.
