First Claim
Patent Images
1. A computer-implemented method comprising:
- determining, based on a multi-word phrase, a word-dependent language model specific to the multi-word phrase and enabling word-level speech verification;
providing the word-dependent language model of the multi-word phase to a speech-recognition engine; and
receiving, from the speech-recognition engine and responsive to the speech-recognition engine receiving one or more human utterances associated with the multi-word phrase, an indication that the one or more utterances is verified or not verified to be the multi-word phrase.

Abstract
This document describes word-dependent language models, as well as their creation and use. A word-dependent language model can permit a speech-recognition engine to accurately verify that a speech utterance matches a multi-word phrase. This is useful in many contexts, including those where one or more letters of the expected phrase are known to the speaker.

14. A computer-implemented method comprising:
-
receiving a word-dependent language model enabling sequential, word-level speech verification of a multi-word phrase; receiving an utterance; and verifying, sequentially, word-by-word, and based on the word-dependent language model, that the utterance does or does not include each word of the multi-word phrase. - View Dependent Claims (15, 16, 17, 18)

19. A computer-implemented method comprising:
-
receiving a multi-word answer to a question and context indicating information about the multi-word answer, the question and the context exposed to a user from which a human utterance in response to the question is expected; determining, based on the context and the multi-word answer, a word-dependent language model specific to the multi-word answer and enabling word-level speech verification; providing the word-dependent language model of the multi-word phase to a speech-recognition engine; and receiving, responsive to the speech-recognition engine receiving the human utterance, an indication that the human utterance is verified or not verified to be the multi-word phrase. - View Dependent Claims (20)
