Try our Voice Characters to automate AI voice agent testing.
Lilac Labs, a pioneer in Quick Service Restaurant (QSR) automation, leverages Hamming to ensure their AI voice agents provide seamless and reliable ordering experiences.
Prior attempts at drive-thru automation often failed due to high costs and poor performance. With Hamming, Lilac Labs tests and refines their voice agents across thousands of real-world scenarios, ensuring they handle background noise, complex orders, and upselling opportunities with ease.

We automate the person taking orders at the drive-thru with voice. Order accuracy is extremely critical for our customers. Getting an order wrong (i.e., missing allergies) means significant financial loss.
Before we had Hamming, we were spending hours per day calling our system by hand. Every time we changed our prompts or function definitions, we would need to retest our system to make sure it still worked and didn't break anything.
We worked closely with the team at Lilac to create 1000s of characters and scenarios that mimic how real customers order food - paying attention to the details like dietary restrictions, allergies, and preferences.
We also created an array of LLM judges that scored the performance of their voice agents for each scenario.
Now, instead of testing voice agents by hand, the team at Lilac could press a button and have our system make 1000s of concurrent calls to their voice agents.
For each phone call, the team had detailed analytics on where their system needed more work.

In production, we gave the team full visibility into how users were interacting with their AI voice agents in production and flagged cases where their agents were struggling.
The team could easily convert calls and traces into test cases and add them to their golden dataset of scenarios.

Our voice agents are trained to mimic human conversations, including accents, background noise, and pauses.
For each call, we automatically score the call quality and provide detailed analytics.
Our AI voice agents can call your agents in any language, including English, French, German, Hindi, Spanish, Italian, and more.
