Business Voice Engine Overview

Business Voice Engine allows Agency administrators and technical team members to manage the AI voice engine used by a Business's agents. You can compare available voice engines, select the appropriate engine during onboarding or change it later, and manually apply engine version updates. After updating, you can verify new calls to ensure the AI agents are functioning as expected.

Important notes

The initial engine is selected during Business Onboarding’s Internal Process step. Only one engine can be assigned to a Business at a time. Versions are never auto-updated; the Agency updates each Business manually.
Engine changes can affect Agent performance because templates may have been tested against a particular version. Ongoing calls finish on the version they started with; new calls after an update use the new version.

Before you start

Open the intended Business’s configuration and confirm its Business Code.
Review the Business’s language needs and existing Agent configuration.

Select or change the engine

Open the Business and scroll to Select a Voice Engine.

Select the voice engine assigned to the business

Choose one engine that fits its calling and language needs.

Select Save. New calls begin using the selected engine immediately.

Engine reference

Engine	Capability	Consideration
General-Purpose	Supports 40+ languages; agent speaks one configured language at a time; source describes highest accuracy for single-language businesses.	Confirm the current supported language list.
Multilingual-Purpose	Speaks multiple languages and detects caller language from speech	Accuracy may dip if caller frequently switches languages within a call.
Indo	Designed for Indian-English community; supports major Indian languages plus English and mixed-language speech.	Accuracy may dip if caller frequently switches languages within a call.

Review a version update

Review the engine card for Update available and compare the current and available versions.
Plan the manual update with the Agency’s Agent owner and test the relevant call scenarios afterward.

Expected result

One selected engine powers new calls for the Business. Version changes occur only when the Agency applies an update.

Verify the result

Reopen Select a Voice Engine and check the selected engine and version.
Place a controlled new call in the Business’s configured language; for multilingual scenarios, test the expected caller-language behavior.
Review several calls after any version update for unexpected changes in the Agent’s performance.

Troubleshooting

Problem or Symptom	Likely Cause	Solution
The required engine is missing.	It may not be available in the selection.	Contact Kickcall Support with the Business’s calling requirements.
Language handling is less accurate than expected.	The chosen engine may not match the language pattern.	Check configured language and engine capabilities; frequent switching can reduce Multilingual-Purpose accuracy.
The version did not update automatically.	Updates are manual per Business.	Review Update available and arrange the manual update.
New calls behave differently after an update.	The Agent template may have been tested against an older engine version.	Review the affected calls and configuration with the Agency’s Agent owner.

Recovery or rollback

You can select a different engine and Save, then test new calls. Do not assume a previous engine version can be restored.

Frequently Asked Questions

Can I assign more than one engine to a business?

No. Only one engine can be active for a business at any time. To switch, just select a different engine and save.

Does updating the engine version affect ongoing calls?

Ongoing calls finish on the engine version they started with. New calls placed after the update use the new version.

Can an engine update impact upcoming calls?

Yes, it may. Agent templates are normally well tested against a specific engine version. If your running agent was built on top of an older engine version and you update the engine, you may see some performance impact on upcoming calls — though the chance of a negative impact is low. We recommend reviewing a few calls after any engine update.
