Patent Application
20060046769
This invention relates generally to a telematics system radio presets system. In particular, the invention relates to a method, system and computer usable medium for establishing radio presets in a mobile vehicle.
Speech recognition systems are used within vehicles with telematics units to initiate phone calls from the in-vehicle mobile phone. The user states one of the nametags associated with a phone number and the telematics unit initiates the phone call. The user is sometimes confused about the nametags. For example, a user may ask to call “Mother” when the nametag was created for “Mom.” Also, a user's recall performance for nametags is sometimes not at the same high level as the recall performance for regular commands.
When a vehicle is in high noise conditions, the speech recognition system is sometimes unable to correlate a spoken word or phrase with the speaker dependent vocabulary stored in system.
In an exemplary situation, the user gives a command, “Call Mom,” and the command is not successful. The speech recognition application software receives a signal to noise ratio (SNR) speech error from the speech recognition engine in response to the unsuccessful command. The speech recognition application software sends an advisory message to the user to reduce the noise level in the car. A user can reduce the noise level in the vehicle by reducing fan levels, closing open windows, ending conversations in the vehicle or taking other appropriate noise reducing actions. The user repeats the command, “Call Mom,” and if the noise level is still too high, the cycle is repeated. After three attempts to receive a spoken command, the telematics system stops providing the advisory message to reduce the noise level. Then the user initiates a connection with the call center or directly dials the in-vehicle mobile phone to make the phone call.
In another exemplary situation, the user gives a command, “Call Mom,” and the speech recognition system correlates the spoken phrase with more than one of the speaker dependent phrases stored in speech recognition system. The speech recognition system then uses an elimination process to determine which phrase the user actually said. The speech recognition application software sends an message to the user asking, “Did you say call Tom?” The user says, “No.” The speech recognition application software sends a second message to the user asking, “Did you say call John?” The user says, “No.” After three attempts to correlate a spoken command, the telematics system stops trying to eliminate the possible matches. Then the user initiates a connection with the call center or directly dials the in-vehicle mobile phone to make the phone call.
Unsuccessful attempts to place calls using verbal commands have a negative impact on several important metrics in the speech recognition application, including a lower task completion rate. The user may also experience some frustration during the unsuccessful attempt.
It is desirable, therefore, to provide a method, system and computer usable medium that overcomes the limitations described above. It is desirable to provide a user with an alternative method to place a call using a nametag when high level noise conditions cause failure or uncertainty in matches within the voice recognition system. It is further desirable that the alternative method to place a call using a nametag in high level noise conditions is simple and easily recalled.
One aspect of the present invention provides a method of initiating a wireless phone call from a mobile vehicle. The method includes storing at least one phone number in a vehicle communication system. The vehicle communication system includes a radio in communication with a telematics unit. The method further includes linking the stored phone number to a radio button, receiving a radio button input, while in a communication mode and placing the call from the telematics unit to the phone number linked to the radio button associated with the radio button input.

During stage S22, the radio preset application in the telematics unit 120 stores at least one phone number in the vehicle communication system. The vehicle communication system includes a radio 136 in communication with the telematics unit 120. Phone numbers may be stored in memory that is in communication with telematics unit 120. In one embodiment, the memory is memory 128 (
During stage S24, the radio preset application in the telematics unit 120 links the stored phone number to a radio button 136A. The computer readable code for linking is stored in the memory 128 and is retrieved by the processor 122 to execute the linking. The computer readable code for linking modifies software in the radio 136. The software modification includes a mapping of the pushed radio button 136A to the stored phone number. After the software modification, a button push of a radio button 136A while telematics unit 120 is in a speech recognition mode, triggers the radio preset application to send a radio button input to the processor 122. In one embodiment, the phone number is linked to the available unlinked radio button 136A with the lowest radio button number.
During stage S26, the radio preset application receives a radio button input while the telematics unit 120 is in the communication mode. The telematics unit 120 is in the communication mode when the speech recognition system is activated. The phrases “communication mode” and “speech recognition mode” are used interchangeably within this document to describe the mode in which the speech recognition system is operating and the radio preset application can be initiated with the push of a radio button 136A.
When the telematics unit 120 is in the communication mode, the audio output from the radio 136 is muted and the radio buttons 136A are no longer operable to select a radio broadcast signal. Instead, a button push to an first radio button triggers the radio preset application to send a first radio button input to the processor 122. In response to receiving the first radio button input, the processor 122 retrieves the stored phone number linked to the associated the first radio button.
In one embodiment, a user pushes a radio button 136A if a call command or dial command is unsuccessful and if the radio button 136A was previously linked to the requested phone number, according to stages S22 and S24. In one embodiment, the user activates the in-vehicle speech recognition unit 138 and pushes the preset radio button 136A to initiate a phone call prior to a call command or dial command attempt.
During stage S28, the telematics unit 120 places a call from the MVCU 110 to the phone number linked to the radio button 136A associated with the radio button input. Processor 122 establishes a communication channel between telematics unit 120 and the telephone associated with the linked phone number. The communication channel is established over one or more wireless carrier systems 140, one or more communication networks 142 and one or more land networks 144.
During stage S32, the user activates an in-vehicle speech recognition unit 138 within the telematics unit 120. The activation can be initiated by a button push or other input sent to telematics unit 120.
During stage S34, the in-vehicle speech recognition unit 138 receives a store command, a phone number and an appellation correlated to the number from the user.
In one embodiment, the user announces, “Store,” into microphone 130. The term “announces into the microphone 130” describes the process of speaking out loud within the vicinity of the microphone 130 in the MVCU 110, so that the microphone 130 picks up the acoustic vibrations from the voice. The vibrations received at the microphone 130 are transmitted as voice signals to the in-vehicle speech recognition unit 138. A speech recognition application installed in in-vehicle speech recognition unit 138 translates the human voice input through microphone 130 to digital signals. In one embodiment, a speech recognition application installed in processor 122 translates the human voice input through microphone 130 to digital signals. In another embodiment, the in-vehicle speech recognition unit 138 is part of the processor 122.
In another embodiment, a store command is initiated by a button push or other command, and the store command is then received by in-vehicle speech recognition unit 138.
In response to the received store command, the in-vehicle speech recognition unit 138 triggers the telematics unit 120 to store the audio files and/or text format files for all the following announced phrases until the in-vehicle speech recognition unit 138 receives a termination command. In one embodiment, the termination command is an oral command, such as, for example, “stop,” “end,” “finish,” or other phrases to indicate termination of the storage command. In another embodiment, the termination command is a button push or other input.
The user then announces a phone number, “#-#-#,” e.g., 555-234-5678, into microphone 130. The phone number is stored, in one embodiment, as a text format file in memory 128. In another embodiment, the phone number text format files are stored in a memory internal to the in-vehicle speech recognition unit 138. In another embodiment, the phone number text format files are stored in a memory internal radio 136.
Then the user announces an appellation, “XXXX,” e.g., “Mary”, to associate with the announced phone number. In one embodiment, the appellation is an identifying phrase such as hospital, police or car repair center. In another embodiment, the appellation is the name of an individual associated with the phone number. In one embodiment, the appellation is a spoken phrase. In another embodiment, the appellation is received using a button push, or using another data entry device. The appellation is stored as a nametag including an file of the entered appellation and is stored in memory that is in communication with telematics unit 120. In one embodiment, the nametag is an audio file of the spoken appellation. In one embodiment, the nametag is stored in memory 128. In another embodiment, the nametag audio files are stored in a memory internal to the in-vehicle speech recognition unit 138. In another embodiment, the nametag audio files are stored in a memory internal to the radio 136.
Stage S36 is optional. During stage S36, the received phone number is compared with previously stored phone numbers. In one embodiment, processor 122 does the comparing. The processor 122 in the telematics unit 120 looks for a match between the text format file for the phone number stored during stage S34 and the text format files for previously stored phone numbers. In one embodiment, if the processor 122 finds a match, the processor 122 checks to see if the text format file for the matched previously stored phone number is linked with a nametag and/or a radio button 136A.
Stage S38 is optional and based on completion of stage S36. During stage S38, the telematics unit 120 notifies the user if the comparison generates a match. Processor 122 generates digital signals, which are translated into voice messages and sent out through speakers 132 to announce, for example, “The telephone number ###-###-#### is already stored.” In one embodiment, the voice messages sent out through speakers 132 announce, “The telephone number ###-###-#### is already stored with nametag XXXX and can be accessed by radio button N,” where N numerically identifies one of the radio buttons 136A on radio 136. In an exemplary announcement, the telematics unit 120 sends out a voice message, “The telephone number 555-234-5678 is already stored with the nametag Mary and can be accessed by radio button 4.”
During stage S40, the radio preset system determines the availability of an unlinked radio button 136A. An unlinked radio button 136A is any radio button that does not have a phone number linked to the radio button. The radio preset system checks each radio button 136A for a mapping to a stored phone number until a radio button 136A without mapping is found. If there is no mapping, the radio button 136A is unlinked. If all the radio buttons 136A are linked, there is no determination of availability.
During stage S42, the telematics unit 120 determines user-selection of radio preset, based on a determination of availability of an unlinked radio button 136A. If there is an available unlinked radio button 136A, the processor 122 generates digital signals, which are translated into voice messages and sent out through speakers 132 to announce, for example, “Do you want radio preset?” In one embodiment, the in-vehicle speech recognition unit 138 generates a digital signal that is transmitted via vehicle communication network 112 to the processor 122 to be sent out from speakers 132 as a voice message.
The telematics unit 120 then monitors for a user response. The user response, in one embodiment, is an oral response of, for example, “Yes,” or, “No,” to determine if there is a user-selection of radio preset. In another embodiment, the user response is a button push or other input. If the user response is negative, there is not a determination of user-selection of radio preset. If the user response is positive, there is a determination of user-selection of radio preset. In one embodiment, microphone 130 receives the user's response. In another embodiment, the user response is received in response to a button push or other input. In embodiments that include an oral input, the oral input is processed by in-vehicle speech recognition unit 138.
During stage S44, the telematics unit 120 provides the phone number, the linked appellation and the number of the linked numerically identified radio button 136A, based on a determination of user-selection of radio preset. The phone number, linked appellation and radio button number may be provided audibly or using a display screen. Thus, for example, if the user responds with a, “Yes,” to the question of stage S42, the telematics unit 120 sends out a voice message, “Phone number ###-###-#### is stored as the nametag XXXX with the radio preset button N,” from the speakers 132. In an exemplary announcement, the telematics unit 120 sends out a voice message, “Phone number 555-234-5678 is stored as the nametag Mary with the radio preset button 4.”
During stage S52, the radio preset application in the telematics unit 120 links the nametag to the stored phone number associated with a radio button 136A. The stored phone number is the number announced as, “###-###-####,” as described above with reference to stage S34 in flowchart 30 of
The nametag is the phrase announced as, “XXXX,” as described above with reference to stage S34 in flowchart 30 of
In one embodiment, the computer readable code for linking is stored in the memory 128 and is retrieved by the processor 122 to execute the linking. The computer readable code for linking the nametag to the stored number modifies software in the radio 136. The software modification includes a mapping of the nametag to the stored phone number. In another embodiment, the computer readable code for linking is stored in the radio 136.
During stage S54, the radio preset application stores the nametag in the vehicle communication system. In one embodiment, the computer readable code for storing a nametag is stored in memory 128 and is retrieved by the processor 122 to execute the storing. In one embodiment, the computer readable code for storing a nametag is stored in radio 136 and is retrieved by the processor 122 to execute the storing. The audio files for nametags are stored in the memory 128 of the telematics unit 120. In one embodiment, audio files for nametags are stored in a memory (not shown) located in the radio 136.
During stage S56, the radio preset application links the stored nametag to the radio button 136A, which is also linked to the stored phone number. As described above with reference to stage S24 in flowchart 20 of
During stage S58, the telematics unit 120 announces the appellation in response to the radio button input. A button push to a radio button 136A triggers the radio preset application to send a radio button input to the processor 122. In response to receiving the radio button input, the processor 122 announces both the stored phone number and the linked nametag associated the radio button 136A. The processor 122 retrieves the stored audio file for the nametag and generates digital signals, which are translated into voice messages. The telematics unit 120 sends the voice messages out through speakers 132 to announce the appellation, which was used to form the audio file for the nametag. As used herein, “announcing” comprises an audible recitation of the data, as well as a display of the data on a display screen, such as a navigation monitor or radio dial.
In one embodiment, the processor 122 retrieves the stored audio file for the nametag and the linked stored text format file for the phone number and announces the appellation and the phone number. In another embodiment, the processor 122 retrieves the stored audio file for the nametag and the linked stored text format file for the phone number and announces the phone number.
During stage S60, the telematics unit 120 monitors for confirmation from a user that the announced appellation correctly identifies the person or facility that the user would like to call. If confirmation is received, the telematics unit 120 places the call from the telematics to the phone number linked to the nametag. In one embodiment, confirmation requires the users to enter a confirmation input such say, “Yes,” into the microphone 130. In another embodiment, the user confirms using a button push or other input.
In stage S74, responsive to the received delete command, telematics unit 120 deletes the audio files and/or text format files for all the announced phrases that follow the delete command until the in-vehicle speech recognition unit 138 recognizes a termination command. The operation of the microphone 130, the processor 122 and the in-vehicle speech recognition unit 138 in receiving and recognizing phrases was described above with respect to stage S34 in flowchart 30 of
For example, if the user announces, “Delete ###-###-####,” e.g., 555-234-5678, into microphone 130, the processor 122, the memory 130 and the in-vehicle speech recognition unit 138 operate to check for a match of the text format file of the announced phone number with the text format file of the stored phone numbers. If a match is found, the matched phone number is deleted from memory 128 and/or a memory in the radio 136. The nametag linked to the deleted phone number is also deleted from memory 128 and/or a memory in the radio 136.
In an alternative embodiment, the user announces, “Delete XXXX,” e.g., Mary, into microphone 130. The processor 122, the memory 130 and the in-vehicle speech recognition unit 138 operate to check for a match of the audio file of the announced appellation with the audio files of the stored nametags. If a match is found, the matched nametag is deleted from memory 128 and/or a memory in the radio 136. The phone number linked to the deleted nametag is also deleted from memory 128 and/or a memory in the radio 136.
During stage S76, the radio preset application unlinks the radio button 136A associated with the deleted phone number.
