1. A vehicle navigation system that generates an outgoing text message comprising: a vehicle interface that permits a user to provide input to and receive output from the vehicle navigation system, the vehicle interface including an input configured to (i) receive a speech signal from a vehicle mounted microphone, wherein the speech signal corresponds to the outgoing text message, and to (ii) receive data from an incoming text message to annunciate the data to a vehicle occupant; a speech recognizer in communication with the input and configured to analyze the speech signal and recognize text of the speech signal; a speech database in communication with the speech recognizer that provides the speech recognizer with samples of recognized digital speech for recognizing the text of the speech signal; a message generator in communication with the speech recognizer that generates the outgoing text message based on the text of the speech signal recognized by the speech recognizer; an output in communication with the message generator that presents the outgoing text message on a display for verification; a validation means that prompts a user to confirm the displayed outgoing text message; a transmitter in communication with the message generator and configured to transmit the outgoing text message over a network upon receipt of the verification; a receiver that receives the incoming text message and provides the incoming text message; where the vehicle interface permits the user to selectively provide the speech signal in complete sentences, word-by-word and letter-by-letter; where the speech database stores samples of spoken letters, words and phrases; where the speech recognizer comprises functionality for interpreting one or more system commands, editing commands and messages and can be activated with a spoken keyword; and further comprises at least one of the following algorithms: a utilization of probability estimates, an analysis of feature vectors and a concatenation of allophones that constitute a linguistic word; and where the transmitter comprises one or more telecommunication units that can selectively communicate the outgoing text message over a store and forward messaging service or as an electronic mail over at least one of the following paths (i) a local area network, (ii) a wireless fidelity network (Wi-Fi), (iii) a wide area network (WAN), (iv) the Internet, (v) a radio network, (vi) a wireless network and (vii) a telephone network.
