Your voice agent is only
as good as your last test.

voxharness calls it, plays the customer in Hindi, Kannada, Telugu, and Tamil, and scores every response. Built by someone who got tired of picking up their own test calls.

How it works

01

Point voxharness at your agent

Give it a phone number, a scenario, and a language — Hindi, Kannada, Telugu, Tamil, or English.

02

It has the conversation for you

TTS speaks each customer line, STT hears the reply, turn by turn. No human ever picks up.

03

Read your scorecard

Latency, repeats, naturalness — one PASS/FAIL verdict, plus a non-zero exit code on regression.
