Japanese Patent JP5761137
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To properly correct acoustic characteristics according to a type of a speaker.SOLUTION: When a speaker device of a conference terminal receives a sound signal for emitting sound (S3;YES), at predetermined timing, the speaker device superimposes attribute information on the sound signal (S5), and emits sound (S6). The conference terminal collects the emitted sound by a microphone (S7), and extracts the attribute information from the sound signal representing the sound (S8). On the basis of an acoustic characteristics correction table which associates respective pieces of attribute information and correction amounts, the conference terminal determines a correction amount associated with the extracted attribute information (S10). Then, the conference terminal corrects sound data to be supplied to the speaker device by the determined correction amount to supply a sound signal to the speaker device (S11). The speaker device emits sound corresponding to the corrected sound signal (S12).
