Voice Agents

Build low-latency conversational phone agents in Lyzr Studio.

Lyzr Studio Voice Agents let you build low-latency conversational phone bots. They support phone number assignment, Realtime and Pipeline engines, knowledge base integration, call recordings, transcripts, and analytics.

When to use Voice Agents

• Inbound customer support lines
• Outbound appointment reminders or sales follow-up calls
• Internal helpdesk by phone
• Voice-first experiences where users should not need a chat UI

Architecture modes

Realtime Engine

Realtime uses audio-to-audio models such as gpt-realtime. It avoids separate STT and TTS layers and is best for low-latency conversation.

Pipeline Engine

Pipeline mode uses a modular stack: STT provider, LLM, and TTS provider. Each component can be configured independently.

Getting started

Access Voice Agents from the voice icon in the Studio sidebar. See Building Voice Agents for configuration and Telephony & Analytics for phone numbers and transcripts.
