Abstract

MéTODO E APARATO PARA MELHORAR A QUALIDADE DE REPRODUçãO DA FALA A presente invenção se refere ao aumento da qualidade de reprodução da fala onde a degradação da qualidade de reprodução da fala é reduzida através da remoção do ruído de uma fala de não-voz. A presente invenção compeende dividir um sinal de fala em uma voz falada e uma fala de não-voz, executar filtragem adaptavél na voz falada para remover o ruído da voz falada, e executar subtração espectral na fala de não-voz.
