Voice Agent
ποΈ Introduction to Voice Agent in Lyzr
Lyzrβs 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 youβre building for customer support, field operations, accessibility, or hands-free automation β voice is the most intuitive interface.
π§ What Powers the Voice Agent?
Lyzr integrates best-in-class services for both speech recognition and generation:
π£οΈ Deepgram β 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.
π ElevenLabs β Text-to-Speech (TTS)
- Converts the agentβs reply into human-like voice output.
- Offers multiple voices with emotional tone and inflection.
- Used to speak the agentβs reply back to the user.
Together, these create a seamless audio pipeline β from voice in β AI thinking β voice out.
