Abstract

"SISTEMA E MéTODO PARA ARMAZENAMENTO EFICIENTE DE MODELOS DE RECONHECIMENTO DE VOZ". um método e sistema que aperfeiçoam o reconhecimento de voz por meio do aperfeiçoamento do armazenamento dos gabaritos de reconhecimento de voz (VR). O armazenamento aperfeiçoado significa que mais modelos de VR podem ser armazenados na memória. Mais modelos de VR podem ser armazenados na memória, mais robusto é o sistema de VR e portanto mais preciso será o sistema de VR. As técnicas de compressão com perda são utilizadas para comprimir modelos de VR. Em uma modalidade, a compressão por Lei-A e a expansão por Lei-A são utilizadas para comprimir e expandir os modelos de VR. Em outra modalidade, a compressão por Lei-Mu e a expansão por Lei-Mu são utilizadas para comprimir e expandir os modelos de VR. Os modelos de VR são comprimidos durante um processo de treinamento e são expandidos durante o reconhecimento de voz.
