System and method for standardized speech recognition infrastructure
View Patent ↗Disclosed herein are systems, methods, and computer-readable storage media for selecting a speech recognition model in a standardized speech recognition infrastructure. The system receives speech from a user, and if a user-specific supervised speech model associated with the user is available, retrieves the supervised speech model. If the user-specific supervised speech model is unavailable and if an unsupervised speech model is available, the system retrieves the unsupervised speech model. If the user-specific supervised speech model and the unsupervised speech model are unavailable, the system retrieves a generic speech model associated with the user. Next the system recognizes the received speech from the user with the retrieved model. In one embodiment, the system trains a speech recognition model in a standardized speech recognition infrastructure. In another embodiment, the system handshakes with a remote application in a standardized speech recognition infrastructure.
1. A method comprising:
receiving speech from a user;
if a user-specific supervised speech model associated with the user is available, retrieving the supervised speech model;
if the user-specific supervised speech model is unavailable and if an unsupervised speech model associated with the user is available, retrieving the unsupervised speech model;
if the user-specific supervised speech model and the unsupervised speech model are unavailable, retrieving a generic speech model; and
recognizing, via a processor, the received speech from the user with the retrieved model.
2. The method of claim 1 , wherein the user-specific supervised speech model, the unsupervised speech model, and the generic speech model are standardized speech models.
3. The method of claim 1 , wherein at least one of the user-specific supervised speech model, the unsupervised speech model, and the generic speech model is publicly available.
4. The method of claim 1 , the method further comprising adapting the retrieved model based on the recognized speech.
5. The method of claim 1 , the method further comprising reusing speech models for later received speech.
6. The method of claim 1 , wherein the supervised speech model, the unsupervised speech model, and the generic speech model are each generated on a different device.
7. The method of claim 1 , wherein at least one of the supervised speech model and the unsupervised speech model is represented as a set of differences from a base speech model.
8. The method of claim 1 , wherein recognizing the received speech from the user is performed off-line at a later time.
9. The method of claim 1 , the method further comprising:
identifying voice commands in the recognized speech; and
controlling elements of a game based on the identified voice commands.
