Knova agents come in four tiers. Ultra is the most natural: the agent listens while it speaks, so callers can interrupt and ask follow-up questions and the agent replies almost straight away, like a person would. Ultra agents can use the same knowledge bases, connected apps, call transfers, and reports as other Knova agents.

​
Choose Ultra

  1. Open AI Agents → Knova Agents and select Voice Agent Studio.
  2. In Team settings, open Intelligence.
  3. Select Ultra — most natural.
  4. Pick a voice, finish setting up the agent, and save.
Ultra has its own list of voices. You can’t play a voice sample for Ultra voices, so test the agent with Try agent in browser to hear how it sounds.

​
Good uses for Ultra

  • Customer service calls where a natural pace matters
  • Callers who often interrupt or ask questions mid-sentence
  • Calls where a faster reply is likely to win more bookings or sales

​
Credit usage

Ultra uses more credits per minute than the other tiers. Settings → Customer Pricing by Tier shows what each tier costs you, and lets you charge customers more for calls answered by higher-tier agents. See Customer pricing by tier.
