Abstract

"QUANTIFICAçãO DE MAGNITUDE ESPECTRAL PARA UM CODIFICADOR DE FALA". Um esquema de quantificação de amplitude para codificadores de fala de baixa taxa de bit inclui o primeiro passo de extrair um vetor de informação espectral a partir de um frame. A energia do vetor é normalizada (1301) para gerar fatores de ganho. Os fatores de ganho são quantificados diferencialmente vetorialmente. Os fatores de ganho normalizados (1301) são amostrados para recepção não uniformemente para gerar um vetor de dimensão fixada com elementos associados com um conjunto de bandas de freq³ência não uniformes. O vetor de dimensão fixada é dividido em dois ou mais sub vetores. Os sub vetores são quantificados diferencialmente, para melhor vantagem com um processo de clonagem harmónica.
