First Claim
Patent Images
1. A method for testing a phonetic decision tree, the method comprising:
- testing a first phonetic decision tree, created using a first set of data, with a second set of data, the second set of data including at least one second term not in the first set of data, by phonetizing terms of the second set of data using the first phonetic decision tree;
categorizing results of the testing into a set of correctly phonetized terms and a set of incorrectly phonetized terms; and
operating at least one processor to create an exception dictionary including at least one term from the set of incorrectly phonetized terms and phonetization information related to the at least one term.

Abstract
The present invention discloses a method for training an exception-limited phonetic decision tree. An initial subset of data can be selected and used for creating an initial phonetic decision tree. Additional terms can then be incorporated into the subset. The enlarged subset can be used to evaluate the phonetic decision tree with the results being categorized as either correctly or incorrectly phonetized. An exception-limited phonetic tree can be generated from the set of correctly phonetized terms. If the termination conditions for the method have been determined to be unsatisfactorily met, then steps of the method can be repeated.

13. A system for phonetic decision tree testing, the system comprising:
-
at least one recording device to store processor-executable instructions; and at least one processor coupled to the at least one recording device and programmed by the processor-executable instructions to act as; a training engine configured to evaluate a phonetic decision tree, created using a first data set of terms of a training data set, using a second set of terms from the training data set and a set of standard pronunciations, the second set of terms comprising terms for evaluating the phonetic decision tree and including at least one second term not in the first data set, wherein the training engine categorizes a result of the evaluation into a set of correctly phonetized terms and a set of incorrectly phonetized terms, wherein the phonetic tree generation engine is configured to create an exception-limited phonetic decision tree from the set of correctly phonetized terms. - View Dependent Claims (14, 15, 16, 17, 23)

18. A method for creating a phonetic tree for speech synthesis comprising acts of:
-
generating an initial phonetic tree from a first training data set of terms and corresponding term pronunciations; creating a second data set including at least one second term not in the first training data set; creating at least one phonetization for at least one term in the second data set using the initial phonetic tree; comparing a first phonetization of the at least one phonetization for a first term of the at least one term to a corresponding correct term pronunciation for the first term; categorizing at least one result of the comparing into a set of correctly phonetized terms and a set of incorrectly phonetized terms; and creating an exception dictionary including at least one incorrectly-phonetized term of the set of incorrectly phonetized terms and phonetization information related to the at least one incorrectly-phonetized term. - View Dependent Claims (19, 20, 21, 22)
