System and method for mobile automatic speech recognition
View Patent ↗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.
1. A method comprising:
transmitting automatic speech recognition data from a first device to a second device, wherein the first device performs speech recognition using automatic speech recognition parameters based on the automatic speech recognition data;
receiving, at the first device, a new set of automatic speech recognition adaptation parameters from the second device, wherein the new set of automatic speech recognition adaptation parameters is based on the automatic speech recognition data; and
using the new set of automatic speech recognition adaptation parameters to update the automatic speech recognition adaptation parameters on the first device.
2. The method of claim 1 , wherein the new set of automatic speech recognition adaptation parameters is also based on stored user specific adaptation data.
3. The method of claim 1 , wherein the automatic speech recognition data comprises one of:
an environment of the first device and multi-modal data associated with a multi-modal input from a user.
4. The method of claim 1 , wherein the first device is remote from the second device.
5. The method of claim 1 , wherein the automatic speech recognition data comprises an automatic speech recognition output from the first device.
6. The method of claim 1 , wherein the first device is a mobile device.
7. The method of claim 1 , wherein the automatic speech recognition data comprises audio data gathered by the first device during automatic speech recognition with a user.
8. A system comprising:
a processor; and
a computer-readable storage medium having instructions stored for controlling the processor to perform operations comprising:
transmitting automatic speech recognition data from a first device to a second device, wherein the first device performs speech recognition using automatic speech recognition parameters based on the automatic speech recognition data;
receiving, at the first device, a new set of automatic speech recognition adaptation parameters from the second device, wherein the new set of automatic speech recognition adaptation parameters is based on the automatic speech recognition data; and
using the new set of automatic speech recognition adaptation parameters to update the automatic speech recognition adaptation parameters on the first device.
9. The system of claim 8 , wherein the system is a mobile device.
10. The system of claim 8 , wherein the new set of automatic speech recognition adaptation parameters is also based on stored user specific adaptation data.
11. The system of claim 8 , wherein the automatic speech recognition data comprises one of:
an environment of the system and multi-modal data associated with a multi-modal input from a user.
12. The system of claim 8 , wherein the system is remote from the second device.
13. The system of claim 8 , wherein the automatic speech recognition data comprises an automatic speech recognition output from the system.
14. The system of claim 8 , wherein the automatic speech recognition data comprises audio data gathered by the system during automatic speech recognition with a user.
15. A computer-readable storage medium having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
transmitting automatic speech recognition data from a first device to a second device, wherein the first device performs speech recognition using automatic speech recognition parameters based on the automatic speech recognition data;
receiving, at the first device, a new set of automatic speech recognition adaptation parameters from the second device, wherein the new set of automatic speech recognition adaptation parameters is based on the automatic speech recognition data; and
using the new set of automatic speech recognition adaptation parameters to update the automatic speech recognition adaptation parameters on the first device.
16. The computer-readable storage medium of claim 15 , wherein the new set of automatic speech recognition adaptation parameters is also based on stored user specific adaptation data.
17. The computer-readable storage medium of claim 15 , wherein the computing device is remote from the second device.
18. The computer-readable storage medium of claim 15 , wherein the automatic speech recognition data comprises one of:
an environment of the computing device and multi-modal data associated with a multi-modal input from a user.
19. The computer-readable storage medium of claim 15 , wherein the computing device is a mobile device.
20. The computer-readable storage medium of claim 15 , wherein the automatic speech recognition data comprises an automatic speech recognition output.
