PROBLEM TO BE SOLVED: To provide a frequency characteristic correction device that automatically corrects a frequency characteristic of an incoming call signal vocally output from a speaker in a user-transparent manner.SOLUTION: The frequency characteristic correction device includes frequency characteristic correction means and correction characteristic information forming means. The correction characteristic information forming means forms correction information about a frequency characteristic to be executed by the frequency characteristic correction means on the basis of a difference between a frequency characteristic of an outgoing call signal obtained when a microphone captures an incoming call sound vocally output from a speaker and reaching the microphone via an echo path and a frequency characteristic of an incoming call signal vocally output from the speaker. |
