πŸŽ™οΈ Introduction to Voice Agent in Lyzr

Lyzr’s Voice Agent feature allows you to build intelligent agents that can understand spoken queries and respond through high-quality, lifelike voice output β€” all without writing a single line of code.

These agents bring true conversational AI to your applications, combining speech interfaces with the reasoning power of large language models (LLMs). Whether you’re building for customer support, field operations, accessibility, or hands-free automation β€” voice is the most intuitive interface.


🧠 What Powers the Voice Agent?

Lyzr integrates best-in-class services for both speech recognition and generation:

πŸ—£οΈ Deepgram – Speech-to-Text (STT)

  • Converts spoken language into accurate, real-time text.
  • Handles natural variations, accents, and noise robustly.
  • Used to transcribe your voice input into query-ready text.

πŸ”Š ElevenLabs – Text-to-Speech (TTS)

  • Converts the agent’s reply into human-like voice output.
  • Offers multiple voices with emotional tone and inflection.
  • Used to speak the agent’s reply back to the user.
