Abstract In this paper, we expand on a new technique for embedding digital information into G.711 encoded speech signals. Using the method of types as a tool to analyze the statistical nature of a digital speech signal, we demonstrate that our embedding scheme is capable of embedding up to 1.6 Kbps of additional information at an average embedded error rate of 10-4. We are able to achieve these embedded rates by not requiring the data to be either hidden or decoded error free. This additional bandwidth can be used for various low data rate applications. We offer such a scheme as a possibility for use in other existing telecommunications links, both wired and wireless, for the purpose of rate enhancement without changing allocated bandwidths or source compression methods.
