Abstract: An audio apparatus and a method of converting an audio signal are provided. The method includes: receiving a first audio signal including a plurality of channels; comparing audio signals of the plurality of channels to estimate a source position of the first audio signal; localizing a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position; converting the first audio signal into a second audio signal including the plurality of channels and at least one channel having, based on the localized source, a different elevation from the plurality of channels; and outputting the second audio signal.

Abstract: 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.

Abstract: Disclosed are an audio apparatus and an audio providing method thereof. The audio providing method includes receiving an audio signal including a plurality of channels, applying an audio signal having a channel, from among the plurality of channels, giving a sense of elevation to a filter to generate a plurality of virtual audio signals to be respectively output to a plurality of speakers, applying a combination gain value and a delay value to the plurality of virtual audio signals so that the plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a plane wave, and respectively outputting the plurality of virtual audio signals, to which the combination gain value and the delay value are applied, through the plurality of speakers. The filter processes the audio signal to have a sense of elevation.
