Abstract

"MéTODO E EQUIPAMENTO PARA INTERCALAR MéTODOS DE QUANTIFICAçãO, DE INFORMAçãO DE LINHA ESPECTRAL EM UM CODIFICADOR DE FALA". Um método e um equipamento para intercalar métodos de quantificação de informação de linha espectral em um codificador de fala incluem quantificar as informação de linha espectral com duas técnicas de quantificação de vetores, a primeira técnica sendo uma técnica baseada em previsão de média não móvel e a segunda técnica sendo uma técnica baseada em previsão de média móvel. Um vetor de informação de linha espectral é um vetor quantificado com a primeira técnica. São computados vetores código de média móvel equivalente para a primeira técnica. Uma memória de um livro código de média móvel de vetores código é atualizada com os vetores código de média móvel equivalente para um número predefinido de frames que foram anteriormente processados pelo codificador de fala. é calculado um vetor de quantificação meta para a segunda técnica com base na memória de livro código de média móvel atualizada. O vetor de quantificação meta é um vetor quantificado com a segunda técnica para gerar um vetor código meta quantificado. A memória do livro código de média móvel é atualizada com o vetor código meta quantificado. Vetores de informação de linha espectral quantificados são derivados a partir do vetor código meta quantificado.
