1. An operator evaluation support device comprising: a speech recording unit configured to record speech times of a customer and an operator during a telephone call from the customer to which the operator attends; a superposition identifying unit configured to refer to the speech recording unit and identify a superposition speech, which is a speech of the operator that has started during a speech of the customer, during the telephone call; a problematic superposition identifying unit configured to identify a problematic superposition speech among the superposition speeches, by comparing a sound quality of a speech of the customer that has started after the superposition speech with a standard sound quality; a call information creating unit configured to refer to the speech recording unit and create telephone call information indicating the identified problematic superposition speech during the telephone call; and a sending unit configured to send the created telephone call information to an administrator terminal used by an administrator who is evaluating the operator.

The operator evaluation support device according to claim 1 , wherein the speech recording unit is configured to record an average-volume-in-speech in association with the speech time of the customer, and the problematic superposition identifying unit is configured to acquire, from the speech recording unit, the average-volume-in-speech of the speech of the customer that has started after the superposition speech, compare the average-volume-in-speech of the speech of the customer that has started after the superposition speech with a standard average volume, and identify the superposition speech as the problematic superposition speech when the average-volume-in-speech of the speech of the customer that has started after the superposition speech is higher than the standard average volume.
