Abstract

　複数の地点(多地点)間を結んで会議等の多地点コミュニケーションを行うための多地点間音声通話装置に関し、劣悪な音質の音声チャネルの受信時にも、再生明瞭度への影響を最小限にする。音質レベル分析部５０４は、音声受信部５０１が受信した各入力チャネルの音声に対し、符号化方式、通信回線状況、ＳＮ比等の音質レベルを特定する。チャネル割振・ミキシング部５０２は、５０４の分析結果に基づき、各入力チャネルの音声から各出力チャネル（出力部５０５、スピーカ５０３）の音声への割振り又はミキシングの処理を制御する。これにより、低音質音声と高音質音声が出力されるスピーカを別々に分離でき、受信音声全体の了解性を高めることができる。
