Abstract

"MéTODO E APARELHO PARA A RECONSTRUçãO DA FALA EM UM SISTEMA DE RECONHECIMENTO DA FALA DISTRIBUìDO". Um método e aparelho são aqui fornecidos para a reconstrução da fala em um sistema de reconhecimento da fala distribuído. MFCCs faltantes são reconstruídas e utilizadas para gerar a fala. Particularmente, a recuperação parcial das MFCCs faltantes é conseguida pela exploração da dependência das MFCCs faltantes no período de pitch transmitido P bem como nas MFCCs transmitidas. Magnitudes harmónicas são então obtidas a partir das MFCCs transmitidas e reconstruídas, e a fala é reconstruída utilizando essas magnitudes harmónicas.
