1. A method for processing sound used in a speech recognition robot, the method comprising:
recognizing an obstacle existing in a travel path, by a robot;
calculating a travel distance to the obstacle, by the robot;
calculating a travel speed, by the robot; and
determining, by the robot, a point in time at which a transient sound due to an impact caused by passing through the obstacle is generated,
wherein the robot is configured to determine the point in time at which the transient sound is generated, based on the travel speed and the travel distance to the obstacle.
