• a memory configured to store data and information;
• a processor configured to:
• receive user speech from a user interactive device through the communication circuit;
• determine whether a service determination is required by interpreting the user speech;
• when the service determination is required, analyze the user speech based on context information of the user interactive device, generate audio and video feedback as an answer to the user speech, and transmit the audio and video feedback to the user interactive device;
• and
• when the service determination is not required, transmit the user speech interpreting result to the user interactive device.
