Test which voice recovers more orders
Split a campaign's shoppers between two or more agent voices, and let Growth Dept CRO work out which one recovers more orders.
Last reviewed November 7, 2026
What you need
Voice tests run on Growth Dept CRO, which keeps each test's status and computes its results. Connect the store's CRO brand first, in Settings, Integrations: paste the CRO brand ID and an API key with the tests:read, tests:write and tests:start scopes. You make the key in Growth Dept CRO under Settings, API keys. ACR checks the key with CRO before it saves it, stores it encrypted and never shows it again.
Without a connected CRO account, the A/B and multivariate options on the agent step are switched off, with a button to connect.
Set up a test
- Open the campaign's AI agent step.
- Under How calls pick a voice, choose A/B test for two voices or Multivariate test for 3 to 26.
- Variant A is the control: the campaign's own voice. Pick the other voices.
- Shoppers split evenly. To change that, edit the shares; they must add up to 100%. Even split puts them back.
- Press Save or Continue. ACR saves the test and creates it in Growth Dept CRO as a draft.
The test plays on the campaign's default language. Other language profiles keep their own voice.
To drop a test that has not started, choose Single voice and save.
Start, pause and stop
Recovery tests lists every test with its status and variants. Start needs the campaign published and starts the test in CRO. Pause and Stop go through CRO too, and a stopped test keeps its results. While a test runs, its voices are locked.
How shoppers are split
The first time the campaign calls a shopper during a running test, ACR puts them in one variant. They hear that voice on every call, in later runs too. Each call uses the campaign's one agent with the variant's voice, so everything else the agent says and does is the same in every variant.
Test runs and simulated calls never join a test.
What ACR tells CRO
| Event | When |
|---|---|
| Call | A call goes out in the variant's voice |
| Answered | A person picks up and talks |
| Recovered | ACR credits an order to the shopper's run, with the order's revenue |
CRO knows each shopper only by a one-way code made from the store and the lead. No name, phone number or email leaves ACR. Nothing is sent while live calling is off or the campaign is still a draft; ACR keeps what happened and sends it once both allow.
Read the results
Each variant shows its share, calls, answered calls, recovered orders, recovery rate, revenue, lift against variant A, and CRO's chance that it beats variant A. Results fetches the latest numbers from CRO; Open in Growth Dept CRO shows the full report.
