AI Voice Agents 101: Unlocking the Future of Customer Conversations

Last updated: June 13, 2025

Inside the AI Voice Agent Pipeline

The Three Pillars

AI voice agents rely on three core technologies seamlessly integrated into a cohesive pipeline:

1. Speech-to-Text (STT)

  • Converts spoken audio into accurate, readable text.

  • Essential for capturing the intent and nuances of customer speech in real-time.

2. Large Language Model (LLM)

  • Processes text input to comprehend context and generate intelligent responses.

  • Enables natural conversational flow, handling even complex interactions effectively.

3. Text-to-Speech (TTS)

  • Turns generated text into clear, natural speech.

  • Offers customizable voice personas, enhancing customer connection and brand consistency.

Smart Interruption Handling

Conversations are rarely linear; interruptions naturally occur. AI voice agents handle these interruptions gracefully by:

  • Instantly detecting user speech during the agent’s response.

  • Pausing naturally, allowing customers to speak without disruption.

  • Quickly recalibrating and continuing the conversation based on new inputs.
