Abstract

"PROCESSO PARA PRODUZIR A PARTIR DE UM SINAL DE FALA ORIGINAL, UMA PLURALIDADE DE PARâMETROS A PARTIR DOS QUAIS UMA APROXIMAçãO DO SINAL DE FALA ORIGINAL PODE SER RECONSTRUìDA, APARELHO DE CODIFICAçãO DE FALA E APARELHO TRANSCEPTOR PARA USO EM UM SISTEMA DE COMUNICAçãO". Na produção de um sinal de fala original, uma pluralidade de parâmetros (ga~ Q~.gf~ Q~), dos quais uma aproximação do sinal de fala original pode ser reconstruída, um sinal adicional ser gerado em resposta ao sinal de fala original, cujo sinal adicional é destinado a representar o sinal de fala original. Pelo menos um dos parâmetros é determinado (69, 71) usando primeira e segunda diferenças entre o sinal de fala original e o sinal adicional. A primeira diferença é uma diferença entre uma forma de onda associada ao sinal de fala original e uma forma de onda associada ao sinal adicional, e a segunda diferença é uma diferença entre um parâmetro de energia derivado do sinal de fala original e um correspondente parâmetro de energia associado ao sinal adicional.
