Method and apparatus for providing interactive agent by using call sequence

An apparatus for providing an interactive agent by using a call sequence, the apparatus comprising:

• a communication module configured to perform communication;
• a memory storing at least one program;
• and
• a processor configured to operate by executing the at least one program,
• wherein the processor is further configured to:
• generate a call sequence based on an input text of a vehicle passenger, by using a first language model that is pre-trained;
• control the communication module to obtain information of interest by executing the call sequence;
• and
• generate an output text corresponding to the input text based on the information of interest, by using a second language model that is pre-trained,
• wherein the call sequence comprises a plurality of calls.
