Abstract

"QUANTIFICAçãO DE CLASSE PARA O RECONHECIMENTO DE FALA DISTRIBUìDA". é revelado um sistema, método e meio lido por computador para quantificar informação de classe e informação de tom de áudio. O método em um sistema de processamento de informação inclui o recebimento e a captura de um quadro do áudio. O método ainda inclui determinar um tom do quadro e calcular uma palavra de código que representa o tom do quadro, em que o primeiro valor de palavra de código indica um tom indefinido. O método ainda inclui determinar uma classe do quadro, em que a classe é qualquer uma de pelo menos duas classes que indicam um tom indefinido e pelo menos uma classe que indica um tom definitivo. O método ainda inclui calcular uma palavra de código que representa a classe do quadro, em que o comprimento da palavra de código é o máximo do número mínimo de bits necessários para representar as pelo menos duas classes e o número mínimo de bits necessários para representar pelo menos uma classe.
