Title:
送信装置および送信方法、送受信装置および送受信方法、並びにプログラムおよび記録媒体
Document Type and Number:
Japanese Patent JP4711099
Kind Code:
B2
Abstract:
The present invention relates to a transceiver which provides a high-quality decoded voice. A mobile telephone 1011 encodes voice data, and outputs the encoded voice data. Furthermore, the mobile telephone 1011 learns quality-enhancement data which improves the quality of a voice output from a mobile telephone 1012, based on voice data used in past learning and newly input voice data, thereby transmitting the encoded voice data and quality-enhancement data. The mobile telephone 1012 receives the encoded voice data transmitted from the mobile telephone 1011, and selects quality-enhancement data correspondingly associated with a telephone number of the mobile telephone 1011. The mobile telephone 1012 decodes the received encoded voice data based on the selected quality-enhancement data. The present invention is applied to a mobile telephone that transmits and receives voices.
