Position-dependent phonetic models for reliable pronunciation identification
First Claim
Patent Images
1. A method comprising:
- identifying a position-dependent phonetic description of each word in a word language model, each position-dependent phonetic description comprising at least one position-dependent phonetic token, each position-dependent phonetic token comprising a phone and a position identifier that identifies a position within a syllable;
a processor using probabilities for words and probabilities for sequences of words in the word language model to set probabilities for position-dependent phonetic tokens and probabilities for sequences of position-dependent tokens to construct a position-dependent phonetic language model; and
the processor storing the position-dependent phonetic language model.

Abstract
A representation of a speech signal is received and is decoded to identify a sequence of position-dependent phonetic tokens wherein each token comprises a phone and a position indicator that indicates the position of the phone within a syllable.

8. A hardware computer storage medium encoded with a computer program, causing the computer to execute steps comprising:
-
using probabilities for words and probabilities for sequences of words in a word language model to set probabilities for position-dependent phonetic tokens and probabilities for sequences of position-dependent phonetic tokens to construct a position-dependent phonetic language model; and storing the position-dependent phonetic language model. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-implemented method comprising:
-
a processor setting probabilities for sequences of position-dependent phonetic tokens through steps comprising developing cross-word counts for sequences of position-dependent phonetic tokens that span multiple words based on probabilities of sequences of multiple words that the sequences of position-dependent phonetic tokens span; and the processor storing the probabilities for sequences of position-dependent phonetic tokens as part of a position-dependent phonetic language model. - View Dependent Claims (16, 17, 18, 19, 20)
