Add to ORKGSUMMARY This study investigates a band extension tech-nique for narrow-band telephony speech. The proposed tech-nique 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 in-dicates that the proposed technique outperforms the conventional technique. key words: band extension, telephony speech, full wave rectifi-cation 1
