Abstract: A method and an apparatus for reducing noise due to a path change of an audio signal output from a device are provided. The method includes determining an input period for canceling the noise by using a time point, at which the path change is sensed, as a reference, when sensing the path change of the audio signal; low-pass filtering the audio signal in the determined input period; and interpolating a first partial signal, which is the low-pass filtered audio signal in a first predetermined period that starts from a start time point of the determined input period, and a second partial signal, which is the low-pass filtered audio signal in a second predetermined period that ends at an end time point of the determined input period, within the determined input period.

Abstract: A method and apparatus of suppressing a vocoder noise are provided. The method includes receiving from a channel decoder a vocoder frame and first information, the first information indicating whether the vocoder frame has an error, generating speech data by performing voice decoding on the vocoder frame, determining whether a tonal noise has been detected in the speech data, if the first information indicates that the vocoder frame has an error, and attenuating the volume of the speech data and outputting the volume-attenuated speech data through a speaker, upon detection of the tonal noise in the speech data.

Abstract translation: 提供抑制声码器噪声的方法和装置。 所述方法包括从信道解码器接收声码器帧和第一信息，所述第一信息指示声码器帧是否具有错误，通过在声码器帧上执行语音解码来产生语音数据，确定在语音中是否检测到音调噪声 数据，如果第一信息指示声码器帧具有错误，并且在检测到语音数据中的音调噪声时，通过扬声器衰减语音数据的音量并输出音量衰减的语音数据。
