Generating text messages using speech recognition in a vehicle navigation system
First Claim
Patent Images
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.

Abstract
A vehicle navigation system may send and receive communications, such as text messages. Speech recognition may generate a text message without affecting a driver'"'"'s control of the vehicle. A user may audibly control the navigation system and generate a text message through a speech recognition element. A microphone may record a user'"'"'s voice, which is then transformed into a text message for transmission. The message may be recorded sentence-by-sentence, word-by-word, or letter-by-letter. The recorded text message may be visually or audibly presented to the user before transmission.

10. A method for transmitting a text message with a navigation system comprising:
-
providing a vehicle interface for permitting a user to provide input to and receive output from a vehicle navigation system; activating an input for receiving a speech signal from a vehicle mounted microphone via the vehicle interface; detecting the speech signal by the input; using a processor for recognizing the speech signal by comparing the speech signal with sample signals stored in a speech database; generating the text message comprising text from the recognized speech signal; outputting the text message for verification, the outputting including displaying at least part of the text message on a display and prompting a user of the navigation system to acknowledge the text message displayed on the display; transmitting the text message upon verification; where the recognizing further comprises processing the speech signal in complete sentences, word-by-word and letter-by-letter, as selected by the user; where the comparing further comprises the use of one or more of the following algorithms;
a utilization of probability estimates, an analysis of feature vectors and a concatenation of allophones that constitute a linguistic word; andwhere the transmitting further comprises selectively sending the text message over a store and forward messaging service or as an electronic mail over at least one of the following paths;
a local area network, a wireless fidelity network (Wi-Fi), a wide area network (WAN), the Internet, a radio network, a wireless network and a telephone network. - View Dependent Claims (11, 12, 13, 14, 15, 16)
