Patent number: 10403271Abstract: A system and method for generating a transcript of an audio input. An embodiment of a system and method may include generating a phonetic lattice by decoding the audio input and producing a transcription based on the phonetic lattice and based on a first language model. A transcription may be analyzed to produce analysis results. Analysis results may be used to select from a plurality of language models, one language model and the selected language model may be used to generate a transcript of the audio input.Type: GrantFiled: June 11, 2015Date of Patent: September 3, 2019Assignee: NICE Ltd.Inventor: Maor Nissan

Patent number: 9418152Abstract: A system and method for receiving an initial search entry to search text data. The text data may be, for example, an N word lattice, transcribed by a text to speech engine. The difference between the initial search entry and one or more entries in the dictionary may be measured. One or more similar entries may be selected from the dictionary that have the smallest measures of difference to the initial search entry. The text data may be searched for the one or more selected similar entries. Each of the searched similar entries found in the text data may be displayed as a search result.Type: GrantFiled: February 9, 2011Date of Patent: August 16, 2016Assignee: NICE-SYSTEMS LTD.Inventors: Maor Nissan, Moshe Wasserblat
