     TECHNICAL FIELD 
       [0002]    This invention relates to wireless communication devices. 
       BACKGROUND 
       [0003]    With the advent of speech applications on mobile computing devices such as cellular (cell) phones or personal digital assistants (PDAs), it is common, and sometimes necessary, to customize each application on a cell phone to the idiosyncrasies and preferences of the cell phone (or PDA) user. For instance, in a phone book the entries are associated with the phone user, the pronunciations might be customized to his or her accent, the phone numbers are certainly personal choice, and the settings of the application, for example, a choice list or not, confirmation or not, are customizable. 
         [0004]    The device user generally spends a substantial amount of time to enter data and customize his or her application. This effort might be lost if the device is broken, stolen, or replaced. While it is standard to synchronize some of the data in these applications with a PC (personal computer) or PDA databases, this generally does not extend to the application or speech customization. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION 
       [0017]      FIG. 1A  illustrates a flow diagram of a process  10  for saving customized application information in mobile communication devices. A user of a mobile communication device customizes specific elements of applications provided by the mobile device. For instance, he or she may have entered new names in the phonebook, trained the digit recognizer to facilitate a digit dial functionality by simply speaking the digits, changed the pronunciation of “number dial” to “numerals”, and have a particular acoustic model. These user-configurable customizations are valued features for users who have unusual vocal characteristics or accents relative to the general population of a market. The device may require the user to make recordings of his or her voice which are then used to customize the applications. The user may have also customized the launch commands by selecting different combinations from a list of different commands, provided specific button mapping, text and audio prompts, labels for phone number types (for example, work vs. office), and language bundles. The user customizes his or her choice list which is a list of possible recognition results that closely match what the user just said. If no single result is obviously the correct one, the application displays a choice list and prompts the user to choose therefrom. The application software appropriately tracks the customization level of the device. The software also has a flag associated with each application, and possibly with each region of each application, so that it knows if there has been any customization since the last time the customization was saved. 
         [0018]    The method  10  for saving customization information of applications on the mobile communications device includes receiving an input from the user of the device per step  12 . This input is either a speech input or a text input. The application program embedded in the device then determines, per step  14 , if the input is a customization input. Once it has been ascertained that the input is a customization input, the application program proceeds, per step  16 , to determine whether it is a new customization input that needs to be saved. Per step  18 , if the input is determined to be a new input that indicates a customization level of the device has been revised, the application program sets an appropriate flag associated with the customization input. The customization input and the corresponding flag are then stored in the device as a file, such as a database using a format that saves the flag indicating that the entry is a new input. The flag may be at least one bit associated with each database entry. For example, one bit may be associated with an automatic update and another bit with a demand update. 
         [0019]      FIG. 1B  is a flow diagram of a process  40  for backing up the customization information onto a remote server which is either a carrier server or a third party server. The mobile communication device has an application that monitors and tracks changes to the customization of the device. The application detects flags indicating changes to customization per step  42 . 
         [0020]    Every mobile communication device such as a cell phone is connected to one or more networks. These networks are not always active, and each network has a different transport mode, data rate, and charge structure associated with its use. Some examples of networks are the voice channel (the standard cell phone channel which is typically a digital channel with data rates from approximately 9 to 25 kbits per second); a low speed data channel used for SMS (Short Messaging Service) and for message indicators; and a high speed digital channel (in CDMA 2000×1 less than 144 kbits per second, depending on service quality); and per UMTS (Universal Mobile Telephoning System) (3G) a digital channel with data rates of less than 2M bytes per second. Some mobile devices are also enabled with digital wireless protocols such as Bluetooth and/or 802.11 available, so there is an alternate high-speed IP (Internet Protocol) network. 
         [0021]    Periodically, or on demand, the mobile device wakes up and polls the data services available to it per step  44 . It then sends all of the updated customization information (i.e., information that has changed since the last transmission of such information) to an information location on either the carrier&#39;s servers or on the servers of a third party provider connected to the carrier. The information is stored in the remote server such that it is associated with the name of the owner (or user) of the mobile device, and with the date of the storage. 
         [0022]    The software sets the aforementioned flag when the associated feature or customization information is updated or modified. The process  40  includes an acknowledgement step  46  wherein the remote server in receipt of the updated customization information sends a message confirming receipt of input back to the mobile device. The software clears the flag per step  48  when that customization information is downloaded to the carrier&#39;s or third party servers. The software only sends information when the flag indicates that it has updated information since the last back-up. In an embodiment, the software provides a full save of all the customizations to a remote server which allows for a customization of a new but compatible mobile communication device. 
         [0023]      FIG. 2  is a flow diagram of a process  70  for downloading, from a remote server (either third party or carrier server), previously saved customizations to applications of a mobile communication device. When the owner or user wants to update the device, or to customize a different device, he or she simply notifies the carrier or service provider with a request for customization per step  74 , and any available network may be used to download the previously saved customization information into the current device per step  76 . “Smart” software in a device analyzes the cost of the various options, and either gives the user a choice of channels, or simply uses the least expensive update path. 
         [0024]    This can be done for any customization information beyond that which was already mentioned including, for example, a new language model, new names for the address or contact book, new pronunciations, and a trained model that the user has adapted to his or her use. 
         [0025]    The customization information that is backed-up is either identified by the carrier or some other third party. Or the software on the phone enables the user to specify the customization information that he or she wants to have backed-up in this way. 
         [0026]    This back-up service can be a service that the carrier (or a third party working through the carrier) sells to users. Thus, it provides a potential new revenue stream for providers of the cell phone services. The user account may be billed for, but not limited to, transmitting updates, storage of information, updating information, and provisioning of new devices. 
         [0027]    A typical platform on which such functionality can be provided is a smartphone  100 , such as is illustrated in the high-level block diagram form in  FIG. 3 . The platform is a cellular phone in which there is embedded application software that includes the relevant above-described functionality. In this instance, the application software includes, among other programs, voice recognition software that enables the user to access information on the phone (for example, telephone numbers of identified persons) and to control the cell phone through verbal commands. The voice recognition software also includes enhanced functionality in the form of a speech-to-text function that enables the user to enter text into an email message through spoken words. 
         [0028]    In the described embodiment, smartphone  100  is a Microsoft PocketPC-powered phone which includes at its core a baseband DSP  102  (digital signal processor) for handling the cellular communication functions including, for example, voiceband and channel coding functions and an applications processor  104  (for example, Intel StrongArm SA-1110) on which the PocketPC operating system runs. The phone supports GSM (global system for mobile communications) voice calls, SMS (Short Messaging Service) text messaging, wireless email (electronic mail), and desktop-like web browsing along with more traditional PDA features. 
         [0029]    The transmit and receive functions are implemented by an RF (radio frequency) synthesizer  106  and an RF radio transceiver  108  followed by a power amplifier module  110  that handles the final-stage RF transmit duties through an antenna  112 . An interface ASIC  114  (application specific integrated circuit) and an audio CODEC  116  (compression/decompression) provide interfaces to a speaker, a microphone, and other input/output devices provided in the phone such as a numeric or alphanumeric keypad (not shown) for entering commands and information. 
         [0030]    The DSP  102  uses a flash memory  118  for code store. A Li-Ion (lithium-ion) battery  120  powers the phone and a power management module  122  coupled to DSP  102  manages power consumption within the phone. Volatile and non-volatile memory for applications processor  114  is provided in the form of SDRAM  124  (synchronized dynamic random access memory) and flash memory  126 , respectively. This arrangement of memory is used to hold the code for the operating system, the code for customizable features such as the phone directory, and the code for any applications software that might be included in the smartphone, including the voice recognition software mentioned herein before. The visual display device for the smartphone includes an LCD (liquid crystal display) driver chip  128  that drives an LCD display  130 . There is also a clock module  132  that provides the clock signals for the other devices within the phone and provides an indicator of real time. 
         [0031]    All of the above-described components are packaged within an appropriately designed housing  134 . 
         [0032]    Since the smartphone described above is representative of the general internal structure of a number of different commercially available smartphones and since the internal circuit design of those phones is generally known to persons of ordinary skill in this art, further details about the components shown in  FIG. 2  and their operation are not being provided and are not necessary to understanding the invention. 
         [0033]    The internal memory of the phone includes all relevant code for operating the phone and for supporting its various functionality, including code  140  for the voice recognition application software, which is represented in block form in  FIG. 2 . The voice recognition application includes code  142  for its basic functionality as well as code  144  for enhanced functionality, which in this case is speech-to-text functionality  144 . The code or sequence of executable instructions for the methods for saving customized application information including acoustic models and adapted vocabulary as described herein are stored in the internal memory of a phone and as such can be implemented on any phone, PDA or generally any communication device having an application processor. 
         [0034]    In view of the wide variety of embodiments to which the principles of the present invention can be applied, it should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the invention. For example, the steps of the flow diagrams may be taken in sequences other than those described, and more or fewer elements may be used in the diagrams. While various elements of the preferred embodiments have been described as being implemented in software, other embodiments in hardware or firmware implementations may alternatively be used, and vice-versa. 
         [0035]    It will be apparent to those of ordinary skill in the art that methods involved in the automatic or commanded backup of customized application information may be embodied in a computer program product that includes a computer usable medium. For example, such a computer usable medium can include a readable memory device, such as, a hard drive device, a CD-ROM, a DVD-ROM, or a computer diskette, having computer readable program code segments stored thereon. The computer readable medium can also include a communications or transmission medium, such as, a bus or a communications link, either optical, wired, or wireless having program code segments carried thereon as digital or analog data signals. The methods for saving customized application information can be implemented on mobile communication devices having different computing platforms. 
         [0036]    Other aspects, modifications, and embodiments are within the scope of the following claims.
