Abstract

método e discriminador para a classificação de diferentes segmentos de um sinal. para classificar os diferentes segmentos de um sinal de que abrange segmentos de pelo menos, um primeiro tipo e um segundo tipo, por exemplo segmentos de áudio e fala, o sinal é classificado como curto prazo (150) com base em pelo menos, um recurso de curto prazo extraído do sinal e um resultado de classificação de curto prazo (152) é entregue. o sinal também é classificado como longo prazo (154) com base em pelo menos, um recurso de curto prazo e em pelo menos, um recurso de longo prazo extraído do sinal e um resultado de classificação de longo prazo (156) é entregue. o resultado de classificação de curto prazo (152) e o resultado de classificação de longo prazo (156) são combinados (158) para fornecer um sinal de saída (160) indicado se um segmento do sinal é de primeiro tipo ou de segundo tipo.
