(JA) 音声符号化装置および音声符号化方法
Abstract: front page image
(EN)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 (XL) and an R-channel signal (XR) individually, and inputs the weighted L-channel signal (XLW) and R-channel signal (XRW) to a monaural signal generating unit (12). This monaural signal generating unit (12) averages the L-channel signal (XLW) and the R-channel signal (XRW), and creates and inputs a monaural signal (XMW) to a monaural signal encoding unit (13). This monaural signal encoding unit (13) encodes the monaural signal (XMW), and outputs an encoding parameter of the monaural signal (XMW) (or a monaural signal encoding parameter).
(FR)Dispositif de codage de voix pouvant générer un signal monaural correct modulé, plus clair et mieux compréhensible, lorsque le signal monaural doit être généré à partir d’un signal stéréophonique. Dans ce dispositif, une unité de pondération (11) pondère individuellement un signal de canal G (XL) et un signal de canal D (XR) et fournit le signal canal G pondéré (XLW) et le signal canal D pondéré (XRW) à une unité de génération de signal monaural (12). Cette unité de génération de signal monaural (12) fait la moyenne du signal de canal G (XLW) et du signal de canal D (XRW) et crée et fournit un signal monaural (XMW) à une unité de codage de signal monaural (13). Cette unité de codage de signal monaural (13) code le signal monaural (XMW) et fournit un paramètre de codage du signal monaural (XMW) (ou un paramètre de codage de signal monaural).
(JA) ステレオ信号からモノラル信号を生成する際に、明瞭性や了解性に富んだ、めり張りある適切なモノラル信号を生成することができる音声符号化装置。この装置では、重み付け部(11)は、Lチャネル信号XおよびRチャネル信号Xそれぞれに重み付けを行って、重み付けしたLチャネル信号XLWおよびRチャネル信号XRWをモノラル信号生成部(12)に入力し、モノラル信号生成部(12)は、Lチャネル信号XLWとRチャネル信号XRWを平均してモノラル信号XMWを生成してモノラル信号符号化部(13)に入力し、モノラル信号符号化部(13)は、モノラル信号XMWを符号化してモノラル信号XMWの符号化パラメータ(モノラル信号符号化パラメータ)を出力する。
