Szukana fraza: [Abstract = "Two practical voice\-coding schemes based on approximate string matching are proposed. The first one is an approximate fixed\-length string\-matching data compression, and the other is a Lempel\-Ziv\-type quasi\-parsing method by approximate string matching. The performance of the two algorithms and their sub\-optimal versions are evaluated. The main advantages of the proposed methods are the asymptotic sequential behaviour of the encoder and the simplicity of the decoder. In particular, a sub\-optimal tree\-structure algorithm is proposed and its real\-time advantages are demonstrated."]
