kbit/sで音声符号化を行うシステムについて述べている．CTVQの復号時のビタビアルゴリズムで用いるトレリスの状態数を低減するために，トレリスの状態間の遷移に符号語を割り当てる遷移ラベル型CTVQを新たに導入し，パラメータの検討を行っている．フェージングのある通言路において，音声を符号化/伝送する計算機シミュレーションを行い，有限状態ベクトル量子化と畳込み符号のタンデム符号化を用いたシステムと比較している．復号音声のセグメンタルSNRが6.5 dBの場合に，提案するシステムはタンデム符号化を用いたシステムに比べて平均Eb/Noで約8dBの利得が得られ，CTVQを用いることで2.8 kbit/s
