Patent number: 8032374Abstract: Provided are an apparatus and method for recognizing continuous speech using search space restriction based on phoneme recognition. In the apparatus and method, a search space can be primarily reduced by restricting connection words to be shifted at a boundary between words based on the phoneme recognition result. In addition, the search space can be secondarily reduced by rapidly calculating a degree of similarity between the connection word to be shifted and the phoneme recognition result using a phoneme code and shifting the corresponding phonemes to only connection words having degrees of similarity equal to or higher than a predetermined reference value. Therefore, the speed and performance of the speech recognition process can be improved in various speech recognition services.Type: GrantFiled: December 4, 2007Date of Patent: October 4, 2011Assignee: Electronics and Telecommunications Research InstituteInventors: Hyung Bae Jeon, Jun Park, Seung Hi Kim, Kyu Woong Hwang

Patent number: 8015016Abstract: Provided are an automatic speech translation system and a method for obtaining accurate translation performance with a simple structure. Because input and output sentences are written in different languages, automatic speech translation requires techniques for processing different languages. Repetition of text processing like morpheme analysis or sentence parsing in conventional automatic speech translation can complicate the overall translation process. Meanwhile, although input and output sentences are written in different languages, they have to have the same meaning and a corresponding sentence form and words. Accordingly, the corresponding words and sentence forms of the two languages can be expressed with a simple structure and utilized in the automatic speech translation process, thereby maintaining consistency during the process and avoiding unnecessary process repetition, which reduces errors and improves performance.Type: GrantFiled: October 25, 2007Date of Patent: September 6, 2011Assignee: Electronics and Telecommunications Research InstituteInventors: Jun Park, Seung Hi Kim, Hyung Bae Jeon, Young Jik Lee, Hoon Chung
