Method and system for identifying and correcting accent-induced speech recognition difficulties
First Claim
1. A system for use in speech recognition, the system comprising:
- an acoustic module accessing a plurality of distinct-language acoustic models, each based upon a different language;
a lexicon module accessing at least one lexicon model; and
a speech recognition output module for generating a first speech recognition output using a first model combination that combines one of the plurality of distinct-language acoustic models with the at least one lexicon model, and in response to a threshold determination, generating a second speech recognition output using a second model combination that combines a different one of the plurality of distinct-language acoustic models with the at least one distinct-language lexicon model.

Abstract
A system for use in speech recognition includes an acoustic module accessing a plurality of distinct-language acoustic models, each based upon a different language; a lexicon module accessing at least one lexicon model; and a speech recognition output module. The speech recognition output module generates a first speech recognition output using a first model combination that combines one of the plurality of distinct-language acoustic models with the at least one lexicon model. In response to a threshold determination, the speech recognition output module generates a second speech recognition output using a second model combination that combines a different one of the plurality of distinct-language acoustic models with the at least one distinct-language lexicon model.

9. A method of generating speech recognition output using a plurality of distinct-language acoustic models, each based upon a different language, and at least one lexicon model, the method comprising the steps of:
-
generating a first speech recognition output using a first model combination that combines one of the plurality of distinct-language acoustic models with the at least one lexicon model; and
in response to a threshold determination, generating a second speech recognition output using a second model combination that combines a different one of the plurality of distinct-language acoustic models with the at least one distinct-language lexicon model. - View Dependent Claims (10, 11, 12, 13, 14)

15. A computer readable storage medium for generating speech recognition output using a plurality of distinct-language acoustic models, each based upon a different language, and at least one lexicon model, the storage medium comprising computer instructions for:
-
generating a first speech recognition output using a first model combination that combines one of the plurality of distinct-language acoustic models with the at least one lexicon model; and
in response to a threshold determination, generating a second speech recognition output using a second model combination that combines a different one of the plurality of distinct-language acoustic models with the at least one distinct-language lexicon model. - View Dependent Claims (16, 17, 18, 19, 20)
