Natural Language Processing (NLP)

Natural Language Processing (NLP) is the field of artificial intelligence concerned with the interaction between computers and human language — enabling machines to read, understand, interpret, and generate text and speech.

Core NLP Tasks

• Intent Detection — determining what the user wants to accomplish.
• Entity Extraction (NER) — identifying specific pieces of information.
• Sentiment Analysis — gauging emotional tone.
• Dialogue State Tracking — maintaining context across turns.

NLP in AI Voice Agents

In a voice agent pipeline, NLP operates on the text transcript produced by speech-to-text. The NLP layer determines caller intent, extracts entities, and selects the appropriate next action.
