Title:

VOICE ENCODING DEVICE, AND VOICE ENCODING METHOD

Document Type and Number:

WIPO Patent Application WO/2006/080358

Kind Code:

A1

Abstract:

A voice encoding device capable of generating a modulated proper monaural signal enriched in clearness and understandability, when the monaural signal is to be generated from a stereophonic signal. In this device, a weighting unit (11) weights an L-channel signal (X_L) and an R-channel signal (X_R) individually, and inputs the weighted L-channel signal (X_LW) and R-channel signal (X_RW) to a monaural signal generating unit (12). This monaural signal generating unit (12) averages the L-channel signal (X_LW) and the R-channel signal (X_RW), and creates and inputs a monaural signal (X_MW) to a monaural signal encoding unit (13). This monaural signal encoding unit (13) encodes the monaural signal (X_MW), and outputs an encoding parameter of the monaural signal (X_MW) (or a monaural signal encoding parameter).
