Abstract: One aspect of the invention relates to a messaging communication scheme for controlling, configuring, monitoring and communicating with a signal processor within a Voice Over Packet (VoP) subsystem without knowledge of the specific architecture of the signal processor. The messaging communication scheme may feature the transmission of control messages between a signal processor and a host processor. Each control message comprises a message header portion and a control header portion. The control header portion includes at least a catalog parameter that indicates a selected grouping of control messages and a code parameter that indicates a selected operation of the selected grouping.

Abstract: An integrated communications device provides an automatic speech recognition (ASR) system to control communication functions of the communications device. The ASR system includes an ASR engine and an ASR control module with an out-of-vocabulary rejection capability. The ASR engine performs speaker independent and dependent speech recognition and also performs speaker dependent training. The ASR engine thus includes a speaker dependent recognizer, a speaker independent recognizer and a speaker dependent trainer. Speaker independent models and speaker dependent models stored on the communications device are used by the ASR engine. A speaker dependent mode of the ASR system provides flexibility to add new language independent vocabulary. A speaker independent mode of the ASR system provides the flexibility to select desired commands from a predetermined list of speaker independent vocabulary.
