  • Patent number: 8065144
    Abstract: A method for speech recognition. The method uses a single pronunciation estimator to train acoustic phoneme models and recognize utterances from multiple languages. The method includes accepting text spellings of training words in a plurality of sets of training words, each set corresponding to a different one of a plurality of languages. The method also includes, for each of the sets of training words in the plurality, receiving pronunciations for the training words in the set, the pronunciations being characteristic of native speakers of the language of the set, the pronunciations also being in terms of subword units at least some of which are common to two or more of the languages. The method also includes training a single pronunciation estimator using data comprising the text spellings and the pronunciations of the training words.

  • Patent number: 7809574
    Abstract: One aspect of the invention involves word recognition that uses scrollable choice lists in which choices are listed in character-order. Another aspect relates to a scrollable, visually-displayed word recognition choice list, where the recognition candidates on the choice list are each associated with a choice-selecting symbol the user can use to select a desired recognition candidate by pressing an associated button, and where the same choice-selecting symbol is used for different choices displayed on the display at different times as a result of scrolling. Another aspect of the invention relates to providing a choice list of best scoring characters for a particular character position in the spelling of a filter that is used to filter word recognition. Another aspect of the invention relates to a choice list used in word recognition in which the choice list can be scrolled horizontally.

  • Patent number: 7797157
    Abstract: Channel normalization for automatic speech recognition is provided. Statistics are measured from an initial portion of a speech utterance. Feature normalization parameters are estimated based on the measured statistics and a statistically derived mapping relating measured statistics and feature normalization parameters. In some examples, the measured statistics comprise measures of an energy from the initial portion of the speech utterance. In some examples, measures of the energy comprise extreme values of the energy.

  • Patent number: 7716058
    Abstract: Large vocabulary speech recognition can automatically turn recognition off in one or more ways. A user command can turn on recognition that is automatically turned off after the next end of utterance. A plurality of buttons can each be associated with a different speech mode and the touch of a given button can turn on, and then automatically turn off, the given button's associated speech recognition mode. These selectable modes can include large vocabulary and alphabetic entry modes, or continuous and discrete modes. A first user input can start recognition that allows a sequence of vocabulary words to be recognized and a second user input can start recognition that turns off after one word has been recognized. A first user input can start recognition that allows a sequence of utterances to be recognized and a second user input can start recognition that allows only a single utterance to be recognized.

  • Patent number: 7676367
    Abstract: A method of constructing a list of alternate transcripts from a recognized transcript includes generating a list of close call records, matching partial sub-histories from the recognized transcript with one of the history pairs stored in each of the records, and substituting the other of the history pairs for the partial sub-history of the recognized transcript. A close call record is generated each time a pair of partial hypotheses attempt to seed a common word. Each close call record includes history information and scoring information associated with a particular pair of partial hypotheses seeding a common word. Alternate transcripts are constructed by substituting close call histories for partial histories of the recognized transcripts, and also by substituting close call histories for partial histories of other alternate transcript.

  • Patent number: 7634403
    Abstract: Word recognition enables a user to have a selected transformation performed on a given word produced by word recognition. In one aspect of the invention, a selectable transformation changes the given word to a differently spelled word having the same word root. In another, a selectable transformation changes a given word to one or more of its homonyms. In yet another, a selectable transformation changes the given word between a representation that spells the word with letters and one that does not. In one aspect of the invention a user can select to display a choice list of transformed words corresponding to a given recognized word and then select to have one of the listed transformed words replace the given word. In another aspect of the invention word recognition favors recognition of words corresponding to a user selected part of speech.

  • Patent number: 7577569
    Abstract: Text-to-speech (TTS) generation is used in conjunction with large vocabulary speech recognition to say words selected by the speech recognition. The software for performing the large vocabulary speech recognition can share speech modeling data with the TTS software. TTS or recorded audio can be used to automatically say both recognized text and the names of recognized commands after their recognition. The TTS can automatically repeats text recognized by the speech recognition after each of a succession of end of utterance detections. A user can move a cursor back or forward in recognized text, and the TTS can speak one or more words at the cursor location after each such move. The speech recognition can be used to produces a choice list of possible recognition candidates and the TTS can be used to provide spoken output of one or more of the candidates on the choice list.

  • Patent number: 7526431
    Abstract: Alphabetic filtering of the speech recognition of words uses a key press to indicate a desired character in an alphabetic filter string, where each key press represents two or more letters. The key presses can be disambiguated by recognizing a key-disambiguation utterance in association with a given key press. A user can select a desired recognition candidate from a choice list produced by such filtered word recognition. Ambiguous alphabetic filtering can be performed iteratively in response to the addition of successive ambiguous key presses. A user can select to re-recognize the utterance using filtering based on ambiguous key input after seeing the results of recognition without such filtering. Unambiguous alphabetic filtering can be performed by using multiple presses of an ambiguous key to disambiguate which letter is intended. A user can select between entering text by either large vocabulary speech recognition or by spelling text by pressing phone keys.
