Simulate callers at scale
Simulates realistic callers at scale for testing a voice agent.
Audio and video / product dossier
NovaSynth by Noveum
Simulates callers and scores voice-agent audio and transcripts across 30+ dimensions.
Product brief
What NovaSynth by Noveum does.
Simulate realistic callers at scale with custom personas, scenarios, interruptions, noise, accents, and network conditions. NovaSynth runs those calls against your voice agent, scores audio and transcripts across 30+ dimensions, and surfaces the failures and fixes that matter to your team.
Why we selected it
Voice agents are moving into customer workflows, and this offers a specific, technically meaningful pre-release testing loop: adversarial caller simulation plus scoring across audio and transcript dimensions. It is more.

FAQ
Before you open it.
What does NovaSynth test?
It tests voice agents by running simulated calls against them.
What can be varied in a simulated caller?
Personas, scenarios, interruptions, noise, accents, and network conditions can be customized.
What does NovaSynth score?
It scores both audio and transcripts across more than 30 dimensions.
Can it run many caller simulations?
Yes. It is described as simulating realistic callers at scale.
