How to Upgrade a Voice AI Agent in Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

Upgrading a Voice AI agent moves it to the new Voice AI Experience for better voice quality and smarter call handling. The upgrade is permanent — duplicate the agent first and re-test prompts after upgrading.

Sparkforge's new Voice AI Experience improves voice quality, call handling, and stability. You upgrade existing agents one at a time, and the upgrade is permanent — so duplicate the agent first and plan to retest your prompts after the move.

What changes after the upgrade

  • Smarter call handling — more natural responses with better timing
  • Better voice quality — clearer tone and lifelike delivery
  • Improved stability — fewer interruptions and glitches
  • Future updates — access to ongoing Voice AI improvements

Before you upgrade

Duplicate the agent so you have a fallback. The upgrade can change how prompts are interpreted, so plan time to retest after the migration.

Upgrade steps

Step 1 — Open AI Agents

  1. Click AI Agents in your sub-account.
  2. Click the Voice AI tab to see the agent list.

Step 2 — Pick the agent

  1. Click the agent's name, or click the three-dot menu and select Edit.
  2. Confirm it's the right agent — the upgrade can't be undone.

Step 3 — Confirm the upgrade

  1. Click Upgrade to New Voice AI Experience in the top-left of the agent edit page.
  2. Review the modal explaining the changes.
  3. Click Upgrade to New Voice AI Experience to complete the move.

After the upgrade

Run sample calls and check tone, clarity, and response accuracy. Adjust prompts if responses drift from your intent. Look for a green UPGRADED badge next to the agent name in the Voice AI list to confirm the migration.

Frequently Asked Questions

Will upgrading break my existing call flows?
It can change how prompts are interpreted. Test thoroughly with sample calls and adjust prompts as needed before routing live traffic.
Can I revert if something goes wrong?
Only if you duplicated the agent before upgrading. The upgrade itself is permanent — there's no in-product rollback.
Does the upgrade cost extra?
No. Upgrading is included in your existing Voice AI subscription.
How do I know an agent is already upgraded?
Upgraded agents show a green UPGRADED badge next to the agent name in the Voice AI list.
Can I upgrade multiple agents at once?
No. Each agent must be upgraded individually so you can test and adjust prompts per agent.
