Method and apparatus for automatically extracting new function of voice agent based on usage log analysis

An apparatus for generating a new function of a voice agent, the apparatus comprising:

• a memory;
• and
• at least one processor connected to the memory,
• wherein the at least one processor is configured to:
• extract a set of utterances of users of the voice agent with respect to the new function of the voice agent by analyzing usage logs of the users,
• generate proto capsules for the set of utterances based on the set of utterances,
• determine a rank of importance of each of the proto capsules,
• identify a vocabulary of a proto capsule having a rank higher than a preset criterion, and
• generate a source code stub for the new function of the voice agent corresponding to the proto capsule having the higher rank, based on the identified vocabulary.
