Abstract

"SISTEMA DE COMPRESSãO DE CONVERSAçãO, MóDULO DE PROCESSAMENTO DE EXCITAçãO, E, CORRENTE DE BITS QUE REPRESENTA UM QUADRO DE UM SINAL DE CONVERSAçãO". Um sistema de compressão de conversação (10) capaz de codificar um sinal de conversação (18) em uma corrente de bits para subseq³ente decodificação para gerar conversação sintetizada (20) é revelado. O sistema de compressão de conversação (10) otimiza a largura de faixa consumida pela corrente de bits, equilibrando a desejada velocidade de bit média com a qualidade perceptual da conversação reconstruída. O sistema de compressão de conversação (10) compreende uma codec de velocidade total (22), uma codec de meia velocidade 24, uma codec de um quarto de velocidade (26) e uma codec de um oitavo de velocidade (28)AS codecs (22, 24-9 26 e 28) são seletivamente ativadas com base em uma seleção de velocidade. Em adição, as codecs de velocidade total e de meia velocidade (22 e 24) são ativadas seletivamente com base em uma classificação de tipo. Cada codec (22, 24, 26 e 28) é seletivamente ativada para codificar e decodificar o sinal de conversação (18) e diferentes velocidade de bits enfatizando diferentes aspectos do sinal de conversação (18) para realçar a qualidade global da conversação sintetizada (20).
