Abstract: A method and system of processing speech information includes segmenting the speech information based upon detection of logical speech boundaries, such as isolated words, prior to compressing and/or transmitting the speech information. In one embodiment, a continuous stream of voice data is analyzed to detect signal segments containing the characteristics of an isolated word, thereby forming frames of speech information. The frames are data compressed to form packets that are transmitted to a remote site. Preferably, the packets include error checking information. In a receive mode, incoming packets are error checked prior to packet decoding. If transmission errors are detected, repairable packets may be corrected. Non-correctable errors cause generation of notice data that are used to notify a listener of the location of lost speech information. Notice data are also generated if the duration between two arriving packets exceeds a preselected threshold.
