摘要： A method and apparatus are provided for reproducing a speech sequence of a user through a communication device of the user. The method includes the steps of detecting a speech sequence from the user through the communication device, recognizing a phoneme sequence within the detected speech sequence and forming a confidence level of each phoneme within the recognized phoneme sequence. The method further includes the steps of audibly reproducing the recognized phoneme sequence for the user through the communication device and gradually highlighting or degrading a voice quality of at least some phonemes of the recognized phoneme sequence based upon the formed confidence level of the at least some phonemes.

摘要： An electronic device (400) for speech dialog includes functions that receive (405, 205) a speech phrase that includes an instantiated variable (315), generate pitch and voicing characteristics (330) of the instantiated variable, and performs voice recognition (410, 220) of the instantiated variable to determine a most likely set of recognition acoustic states (335). A trained map (358) is established (115) that maps recognition feature vectors derived from training speech (105) to synthesis feature vectors derived from the same training speech (110). Recognition feature vectors that represent the most likely set of recognition acoustic states for the recognized instantiated variable are converted to a most likely set of synthesis acoustic states (420) in accordance with the map. The electronic device may generate (421, 440, 445) a synthesized value of the instantiated variable using the most likely set of synthesis acoustic states and the pitch and voicing characteristics extracted from the instantiated variable.

摘要： An electronic device (300) for speech dialog includes functions that receive (305, 105) a speech phrase that comprises a request phrase that includes an instantiated variable (215), generate (335, 115) pitch and voicing characteristics (315) of the instantiated variable, and performs voice recognition (319, 125) of the instantiated variable to determine a most likely set of acoustic states (235). The electronic device may generate (335, 140) a synthesized value of the instantiated variable using the most likely set of acoustic states and the pitch and voicing characteristics of the instantiated variable. The electronic device may use a table of previously entered values of variables that have been determined to be unique, and in which the values are associated with a most likely set of acoustic states and the pitch and voicing characteristics determined at the receipt of each value to disambiguate (425, 430) a newly received instantiated variable.

摘要： A tailored speaker-independent voice recognition system has a speech recognition dictionary (360) with at least one word (371). That word (371) has at least two transcriptions (373), each transcription (373) having a probability factor (375) and an indicator (377) of whether the transcription is active. When a speech utterance is received (510), the voice recognition system determines (520, 530) the word signified by the speech utterance, evaluates (540) the speech utterance against the transcriptions of the correct word, updates (550) the probability factors for each transcription, and inactivates (570) any transcription that has an updated probability factor that is less than a threshold.

In situations where titles are returned to the user, additional steps of associating the words with a title and scoring the title take place. The highest-scored titles are provided to the user as the displayed results.

摘要： A method and apparatus for ordering results from a query is provided herein. During operation, a spoken query is received and converted to a textual representation, such as a word lattice. Search strings are then created from the word lattice. For example a set search strings may be created from the N-grams, such as unigrams and bigrams, of the word lattice. The search strings may be ordered and truncated based on confidence values assigned to the n-grams by the speech recognition system. The set of search strings are sent to at least one search engine, and search results are obtained. The search results are then re-arranged or reordered based on a semantic similarity between the search results and the word lattice.

摘要： A method, system and communication device for enabling voice-to-voice searching and ordered content retrieval via audio tags assigned to individual content, which tags generate uniterms that are matched against components of a voice query. The method includes storing content and tagging at least one of the content with an audio tag. The method further includes receiving a voice query to retrieve content stored on the device. When the voice query is received, the method completes a voice-to-voice search utilizing uniterms of the audio tag, scored against the phoneme latent lattice model generated by the voice query to identify matching terms within the audio tags and corresponding stored content. The retrieved content(s) associated with the identified audio tags having uniterms that score within the phoneme lattice model are outputted in an order corresponding to an order in which the uniterms are structured within the voice query.
