Abstract: A method of operating a communication system includes: receiving a conditional communication for communicating the conditional communication from a sender to a receiver; determining with a control circuit a delivery condition for communicating the conditional communication to the receiver based on the sender; and communicating the conditional communication based on the delivery condition.

Abstract: A method of operation of a navigation system includes: detecting a message overlap between a current audio message and a message delivery timeframe of a contemporaneous audio message; determining an audio message interchange between the current audio message and a contemporaneous audio message based on a message waveform of the current audio message, a remaining message duration of the current audio message, or a combination thereof; and delivering the current audio message and the contemporaneous audio message based on the audio message interchange.

Abstract: A computer implemented reading tutor comprises a player for outputting a response. An input block implementing a plurality of functions such as silence detection, speech recognition, etc. captures the read material. A tutoring function compares the output of the speech recognizer to the text which was supposed to have been read and generates a response, as needed, based on information in a knowledge base and an optional student model. The response is output to the user through the player. A quality control function evaluates the captured read material and stores the captured material in the knowledge base under certain conditions. An auto-enhancement function uses information available to the tutor to create additional resources such as identifying rhyming words, words with common roots, etc., which can be used as responses.
