Abstract
DISPOSITIVO DE CODIFICAçãO DE VOZ E MéTODO DE CODIFICAR VOZ. A presente invenção refere-se a um dispositivo de codificação de voz capaz de gerar um sinal monoauricuíar próprio modulado melhorado em clareza e inteligibilidade, quando o sinal monoauricular está para ser gerado a partir de um sinal estereofónico. Neste dispositivo, uma unidade de pesagem (11) pesa um sinal de canal-L (X~ L~) e um sinal de canal-R (X~ R~) individualmente, e introduz o sinal de canal-L pesado (X~ LW~) e o sinal de canal-R (X~ RW~) pesado em uma unidade de geração de sinal monoauricular (12). Esta unidade de geração de sinal monoauricular (12) calcula a média do sinal de canal-L (X~ LW~) e do sinal de canal-R (X~ RW~), e cria e introduz um sinal monoauricular (X~ MW~) em uma unidade de codificação de sinal monoauricuíar (13). Esta unidade de codificação de sinal monoauricular (13) codifica o sinal monoauricular (X~ MW~), e emite um parâmetro de codificação do sinal monoauricular (X~ MW~) (ou um parâmetro de codificação de sinal monoauricular).
