Este estudo investiga uma técnica de extensão de banda para fala telefônica em banda estreita. A técnica proposta emprega retificação de onda completa que gera de forma não linear sobretons de banda alta a partir da banda baixa. Com o objetivo de aprimorar a técnica convencional, este estudo investiga um controle de ganho quadro a quadro baseado na estimativa do parâmetro de ganho da fala telefônica em banda estreita. Uma avaliação subjetiva indica que a técnica proposta supera a técnica convencional.

Abstract: This study investigates a band extension technique for narrow-band telephony speech. The proposed technique employs full wave rectification that nonlinearly generates high-band overtones from the low band. In order to improve the conventional technique, this study investigates a frame-by-frame gain control based on the estimation of gain parameter from narrow-band telephony speech. A subjective evaluation indicates that the proposed technique outperforms the conventional technique.
