Dialect-specific acoustic language modeling and speech recognition
First Claim
1. A system for training acoustic models for automatic speech recognition comprising:
- a dialect recognition unit configured to distinguish phones of a standard form language and at least one dialect for the language and to identify portions of an acoustic training data set that conform to the at least one dialect based on the distinguished phones of the at least one dialect; and
a controller, implemented by at least one processor, configured to train at least one dialect language model for automatic speech recognition based on the portions of the acoustic training data set that are identified as conforming to the at least one dialect.

Abstract
Methods and systems for automatic speech recognition and methods and systems for training acoustic language models are disclosed. One system for automatic speech recognition includes a dialect recognition unit and a controller. The dialect recognition unit is configured to analyze acoustic input data to identify portions of the acoustic input data that conform to a general language and to identify portions of the acoustic input data that conform to at least one dialect of the general language. In addition, the controller is configured to apply a general language model and at least one dialect language model to the input data to perform speech recognition by dynamically selecting between the models in accordance with each of the identified portions.

13. A system for automatic speech recognition comprising:
-
a dialect recognition unit configured to analyze acoustic input data to compute probabilities that portions of the input data conform to a standard form language and probabilities that the portions of the input data conform to at least one dialect of the standard form language; and a controller, implemented by at least one processor, configured to apply a standard form language model and at least one dialect language model to the input data to perform speech recognition by weighting the models in accordance with each of the computed probabilities. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
