To transmit data over a mobile telephone speech channel a source encoder is replaced by a transcoder, a conversion table and/or a concatenation circuit in order to choose from the words produced by the source encoder the ones that are the most robust and which can without difficulty withstand speech
To transmit data over a mobile telephone speech channel a source encoder is replaced by a transcoder, a conversion table and/or a concatenation circuit in order to choose from the words produced by the source encoder the ones that are the most robust and which can without difficulty withstand speech synthesis followed by an inverse analysis to reconstitute streams of the bits of the data to be transmitted.
