$0.05 - $0.20 per minute of conversation200ms round-trip latency

The Problem

Automate level 1 customer support over the phone with an agent that can handle complex dialogue flows in real time.

Expected Outcome

A 24/7 AI voice agent capable of handling high-volume, real-time phone support.

Tool Chain

Implementation Steps

  1. 1

    Call Initiation and Connection

    A user calls the dedicated support number, connecting via a telephony API to the agent platform.

  2. 2

    Real-Time Speech-to-Text

    User's speech is converted to text instantly using Retell's low-latency ASR.

  3. 3

    LLM Response Generation

    The text is fed to a custom-trained LLM (via Retell webhook) to determine the next action/response.

    Whisper (OpenAI API)
  4. 4

    Text-to-Speech Synthesis and Stream

    The generated response text is synthesized back into audio and streamed back to the user with low latency.

    OpenAI TTS

Alternatives

Step 1

A viable alternative to Twilio for core telephony connection.

Cost Impact: N/A

Step 3

More robust for flow-based, finite state machine dialogue.

Cost Impact: +5%
