This bankruptcy describes the software of however VoIP for covert conversation. The analysis of VoIP trends used for however broadening a model. Matrix coding lets however you embed thriller speech information within VoIP G.729 Communication flows. This method uses 2.4kbps MELP (mystery speech) and G.729 (public companies). This article discusses however the implementation and operation of embedding/extraction algorithms. These algorithms have a however high embedding fee (up to 2. Four kbps) and are smooth for customers to put into effect.
