A voice recognition system includes a call connection control device that controls the call destination of a user, and a computer. The computer is configured to perform voice recognition of speech voice data of the user, determine an intention of a speech of the user based on a voice recognition result of the speech voice data, evaluate the reliability of a response generated by the computer for the user based on the determined intention of the speech of the user, and cause the call connection control device to switch the call destination of the user to an operator terminal in a case where the reliability of the response is equal to or less than a threshold value.
