Patent number: 10529329Abstract: A method and apparatus for improving the performance of voice recognition in a mobile device are provided. The method of recognizing a voice includes: monitoring the usage pattern of a user of a device for inputting a voice; selecting predetermined words from among words stored in the device based on the result of monitoring, and storing the selected words; and recognizing a voice based on an acoustic model and predetermined words. In this way, a voice can be recognized by using prediction of whom the user mainly makes a call to. Also, by automatically modeling the device usage pattern of the user and applying the pattern to vocabulary for voice recognition based on probabilities, the performance of voice recognition, as actually felt by the user, can be enhanced.Type: GrantFiled: November 3, 2017Date of Patent: January 7, 2020Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Kyu-hong Kim, Jeong-su Kim, Ick-sang Han
