Voice agent testing for transportation & logistics
Stop testing scenarios by hand. Automate them in minutes.
From driver status calls to load negotiations, test your logistics voice agents at scale. Run 100 test calls simultaneously and get results in minutes, not weeks.
Hamming works with
All integrations
Auto-generate driver and carrier call scenarios
Create test suites for outbound driver status calls, inbound load negotiations, and dispatch coordination, automatically from your prompts.
Driver status collection calls
- Test outbound calls for delivery status, ETA updates, and location check-ins
- Simulate drivers with varying accents, background noise, and connection quality
- Validate status updates sync correctly with your TMS and dispatch systems
Load negotiation and pricing
- Test inbound calls from carriers negotiating rates on posted loads
- Validate pricing rules, counter-offer handling, and deal confirmation
- Check order creation and load assignment workflows
Dispatch and fleet coordination
- Test load assignment, route updates, and pickup confirmations
- Validate driver availability checks, break scheduling, and shift management
- Check that the agent respects hours-of-service rules and safety protocols
Test edge cases that break logistics voice agents
From bad cell signal to heavy accents, test the scenarios that cause real failures before they reach drivers and carriers in production.
Accent and language variations
- Test with 65+ language variants and regional accents
- Simulate drivers with varying English proficiency levels
- Validate understanding across different speech patterns and speeds
Background noise and interruptions
- Simulate traffic noise, engine sounds, and wind from moving vehicles
- Test interruption handling when drivers speak over your agent
- Validate call quality under poor cellular network conditions
Adversarial and edge case scenarios
- Test confused drivers providing incomplete or incorrect information
- Validate handling of frustrated callers and escalation workflows
- Catch commitments the agent should not make (pricing, timelines)

Frequently asked
questions.
Browse every answer on the FAQ pageIf your calls take 5 minutes each, you'll have results for your entire test batch in about 7 to 8 minutes. We run all tests in parallel. Teams go from setup to a first test report in under 10 minutes.
Yes. We support 65+ languages and can simulate drivers with varying accents, English proficiency levels, and speech patterns. This is critical for logistics companies working with diverse driver populations.
Hamming includes traffic noise, vehicle sounds, and wind simulation. You can challenge your voice agent with realistic road conditions to ensure it performs well when drivers are calling from their trucks.
Yes. If you've been tracking test scenarios in Excel or Google Sheets, you can import them directly into Hamming. We provide an example file structure to make migration easy.
Yes. Every test call is recorded and available for playback. You can listen to exactly what happened, see the full transcript, and understand why specific guardrails passed or failed.
Hamming can simulate interruptions at specific keywords or time intervals (e.g., every 10 to 15 seconds). This tests whether your agent gracefully handles being cut off mid-sentence.
It depends on your stack. Hamming measures time to first word and turn-by-turn latency on every test call, so you can hold your agent to your own target before going live.
Yes. Configure Slack or email notifications to alert your team immediately when test failures occur. This is especially useful for automated regression testing and monitoring.
