20090012792 | SPEECH RECOGNITION SYSTEM - A speech recognition system is provided for selecting, via a speech input, an item from a list of items. The speech recognition system detects a first speech input, recognizes the first speech input, compares the recognized first speech input with the list of items and generates a first candidate list of best matching items based on the comparison result. The system then informs the speaker of at least one of the best matching items of the first candidate list for a selection of an item by the speaker. If the intended item is not one of the best matching items presented to the speaker, the system then detects a second speech input, recognizes the second speech input, and generates a second candidate list of best matching items taking into account the comparison result obtained with the first speech input. | 01-08-2009 |
20090182559 | CONTEXT SENSITIVE MULTI-STAGE SPEECH RECOGNITION - A system enables devices to recognize and process speech. The system includes a database that retains one or more lexical lists. A speech input detects a verbal utterance and generates a speech signal corresponding to the detected verbal utterance. A processor generates a phonetic representation of the speech signal that is designated a first recognition result. The processor generates variants of the phonetic representation based on context information provided by the phonetic representation. One or more of the variants of the phonetic representation selected by the processor are designated as a second recognition result. The processor matches the second recognition result with stored phonetic representations of one or more of the stored lexical lists. | 07-16-2009 |
20100211390 | Speech Recognition of a List Entry - The present invention relates to a method of generating a candidate list from a list of entries in accordance with a string of subword units corresponding to a speech input in a speech recognition system, the list of entries including plural list entries each comprising at least one fragment having one or more subword units. For each list entry, the fragments of the list entry are compared with the string of subword units. A matching score for each of the compared fragments based on the comparison is determined. The matching score for a fragment is further based on a comparison of at least one other fragment of the same list entry with the string of subword units. A total score for each list entry is determined based on the matching scores for the compared fragments of the respective list entry. A candidate list with the best matching entries from the list of entries based on the total scores of the list entries is generated. | 08-19-2010 |
20100305947 | Speech Recognition Method for Selecting a Combination of List Elements via a Speech Input - The invention provides a speech recognition method for selecting a combination of list elements via a speech input, wherein a first list element of the combination is part of a first set of list elements and a second list element of the combination is part of a second set of list elements, the method comprising the steps of receiving the speech input, comparing each list element of the first set with the speech input to obtain a first candidate list of best matching list elements, processing the second set using the first candidate list to obtain a subset of the second set, comparing each list element of the subset of the second set with the speech input to obtain a second candidate list of best matching list elements, and selecting a combination of list elements using the first and the second candidate list. | 12-02-2010 |
