Patent number: 8365070Abstract: A spelling correction system and method automatically recognizes and corrects misspelled inputs in an electronic device with relatively lower computing power. In a learning process, a misspelling correction dictionary is constructed on the basis of a corpus of accepted words, and context-sensitive strings are selected from among all the strings registered in the dictionary. Context information about the context-sensitive strings is acquired. In an applying process, at least one target string is selected from among all the strings in a user's input sentence through the dictionary. If the target string is one of the context-sensitive strings, the target string is corrected by use of the context information.Type: GrantFiled: April 7, 2009Date of Patent: January 29, 2013Assignees: Samsung Electronics Co., Ltd., Knu-Industry Cooperation FoundationInventors: Hee Jun Song, Young Hee Park, Hyun Sik Shim, Jong Gyu Ham, Hark Soo Kim, Joo Ho Lee, Se Hee Lee

Patent number: 8234232Abstract: A word-spacing correction system and method are provided to automatically recognize and correct errors in the spacing of word inputs in an electronic device with relatively low computing power. In a learning process, probability information about each feature is created from a corpus of correct words, and then error correction rules are created by applying the probability information to a corpus of incorrect words from which all spaces between words of the corpus of correct words are removed. In an applying process, word-spacing in a user's input sentence is corrected by applying the probability information and the error correction rules to the user's input sentence.Type: GrantFiled: April 7, 2009Date of Patent: July 31, 2012Assignees: Samsung Electronics Co., Ltd., Knu-Industry Cooperation FoundationInventors: Hee Jun Song, Young Hee Park, Hyun Sik Shim, Jong Gyu Ham, Hark Soo Kim, Jong Hwan Kim, Yeong Kil Song

Publication number: 20100029208Abstract: A host apparatus for wirelessly communicating with a headset by Bluetooth® is provided. An audio Digital Signal Processor (DSP) performs Pulse Code Modulation (PCM) on sound source data when a type of the headset is a mono headset. The audio DSP performs Universal Asynchronous Receiver Transmitter (UART) modulation on the sound source data when a type of the headset is not a mono headset. A Bluetooth® communication unit transmits the data modulated by the audio DSP to the headset.Type: ApplicationFiled: July 29, 2009Publication date: February 4, 2010Applicant: Samsung Electronics Co., Ltd.Inventors: Hyang-Bok Lee, Hark-Soo Kim
