Abstract
A system and method of updating automatic speech recognition parameters on a mobile device are disclosed. The method comprises storing user account-specific adaptation data associated with ASR on a computing device associated with a wireless network, generating new ASR adaptation parameters based on transmitted information from the mobile device when a communication channel between the computing device and the mobile device becomes available and transmitting the new ASR adaptation data to the mobile device when a communication channel between the computing device and the mobile device becomes available. The new ASR adaptation data on the mobile device more accurately recognizes user utterances.

Claim
1. A method comprising:
identifying, by a system including a processor, automatic speech recognition parameters for use by a speech recognition system; and
transmitting, by the system and to the speech recognition system, a set of automatic speech recognition adaptation parameters that enable updating the automatic speech recognition parameters of the speech recognition system.
2. The method of claim 1, wherein identifying the automatic speech recognition parameters comprises:
receiving, at the system and from the speech recognition system, speech recognition data associated with speech recognition performed by the speech recognition system; and
identifying, at the system, the automatic speech recognition parameters based on the speech recognition data and user-specific information stored at the system that are associated with a user of the speech recognition system.
3. The method of claim 2, further comprising:
generating, by the system, the set of automatic speech recognition adaptation parameters based on the automatic speech recognition parameters.
4. The method of claim 3, wherein the generating the automatic speech recognition adaptation parameters comprises synchronizing the automatic speech recognition parameters with the user-specific information.
5. The method of claim 3, wherein the generating the automatic speech recognition adaptation parameters comprises normalizing the automatic speech recognition parameters using frequency wrapping.
6. The method of claim 5, wherein the frequency warping is performed by selecting a singular linear warping function using normalized automatic speech recognition parameters.
7. The method of claim 2, wherein the user-specific information comprises information reflective of common terminologies spoken by a user associated with the speech recognition system and environments in which the speech recognition system is used.
8. The method of claim 2, wherein the speech recognition data include auditory information indicating an environment in which the speech recognition system performed the speech recognition and multi-modal input from a user associated with the speech recognition system which is used in performing the speech recognition.
9. A network device, comprising:
a memory having computer-readable instructions stored therein; and
a processor configured to execute the computer-readable instructions to,
identify automatic speech recognition parameters for use by a speech recognition system; and
transmit, to the speech recognition system, a set of automatic speech recognition adaptation parameters that enable updating the automatic speech recognition parameters of the speech recognition system.
10. The network device of claim 9, wherein the processor is further configured to generate the set of automatic speech recognition adaptation parameters based on the automatic speech recognition parameters.
11. The network device of claim 10, wherein the generating of the automatic speech recognition adaptation parameters further comprises synchronizing the automatic speech recognition parameters with user-specific information.
12. The network device of claim 10, wherein the generating of the automatic speech recognition adaptation parameters further comprises normalizing the automatic speech recognition parameters using frequency wrapping.
13. The network device of claim 9, wherein the speech recognition system is a mobile device.
14. The network device of claim 13, wherein the network device is a server that is communicatively coupled to the speech recognition system.
15. The network device of claim 14, wherein the mobile device and the server communicate intermittently.
16. A non-transitory computer-readable medium having computer-readable instructions stored thereon, which when executed by one or more processors, cause the one or more processors at a network node to perform operations comprising:
identifying automatic speech recognition parameters for use by a speech recognition system; and
transmitting, to the speech recognition system, a set of automatic speech recognition adaptation parameters that enable updating the automatic speech recognition parameters of the speech recognition system.
17. The non-transitory computer-readable medium of claim 16, wherein identifying the automatic speech recognition parameters comprises:
receiving, from the speech recognition system, speech recognition data associated with speech recognition performed by the speech recognition system; and
identifying the automatic speech recognition parameters based on the speech recognition data and stored user-specific information.
18. The non-transitory computer-readable medium of claim 17, wherein the speech recognition data include auditory information indicating an environment in which the speech recognition system performed the speech recognition and multi-modal input from a user associated with the speech recognition system which is used in performing the speech recognition.
19. The non-transitory computer-readable medium of claim 16, wherein the operations further comprise:
generating the set of automatic speech recognition adaptation parameters based on the automatic speech recognition parameters.
20. The non-transitory computer-readable medium of claim 19, wherein the generating of the automatic speech recognition adaptation parameters further comprises normalizing the automatic speech recognition parameters using frequency wrapping.
