Overview

What makes Karasu different?

LLM-native, voice-first platform built for realtime production calls.

Other solution

Legacy IVR flow

Mostly keypad routing with rigid tree logic.

  • Menu-first conversations
  • Slow to update call flows
  • Handles predictable paths only
  • Weak support for natural dialogue

Other solution

Stacked voice vendors

Separate STT, LLM, TTS and telephony contracts.

  • Multiple dashboards and billing lines
  • Hidden add-on costs at scale
  • Higher latency across hops
  • Operational complexity for each release

Our solution

Karasu realtime voice AI

Single API and single meter for production-grade calls.

  • Natural, human-like conversations
  • Fast setup with minimal configuration
  • Handles complex edge cases in-call
  • Supports inbound and outbound workflows

Live voice calls

Human-standard AI voice agent, out of the box

Proprietary voice orchestration delivers human-quality, low-latency phone conversations at scale, with speech, reasoning, and audio tuned together so every turn feels responsive and natural on real production calls.

  • Lowest Latency

    Realtime orchestration keeps turn response fast so calls stay fluent and interruptions feel natural.

  • Ultra Realistic Voice

    Voice output is tuned for natural cadence and clarity, making agents sound less robotic on production calls.

  • Turn Taking

    Conversation timing adapts in-call so agents know when to listen, pause, and respond without clipping users.

Voice experience
