  • Voice processing apparatus and method for detecting and correcting errors in voice data
    Patent number: 9021318
    Abstract: A voice processing apparatus is provided in an ADPCM (Adaptive Differential Pulse Code Modulation) voice transmission system in which voice data that is differentially quantized through an ADPCM scheme is transmitted. The voice processing apparatus includes an error detector which detects whether or not an error occurs in a transmission frame containing data that indicates a differential value, and an error determiner which determines a level of the error detected by the error detector when the error detector detects the error. The voice processing apparatus also includes a voice processor which corrects the voice data with a correction value depending on the level of the error detected by the error detector and an ADPCM decoder which decodes the voice data corrected by the voice processor.
