Driving an excellent call experience.
What every other platform still can't get right: metallic voices, dead air, awkward pauses…
Zero dead air
Our agents make small talk, just like we do, especially while retrieving information and performing tool calls. It makes the conversation more human.
Turn taking
A proprietary model that lets the agent pause only when you say something relevant, not at every “haan,” “hmm,” or “ohh.”
Effective communication
Our agents adapt. They switch to the language and dialect you’re comfortable with, no matter how often you change language during the conversation.
Ultra realistic voice
Voices on Vaani come with emotional tags. Pitch, pace, and breath move with the conversation and shift with your context, so it feels more real.
Lowest latency
Vaani has best-in-class responsiveness, with ~450ms p90 latency, so conversations stay fluent.
From first agent to millions of calls
Real conversations in Hindi, English, Kannada, and more — from the teams already shipping on Vaani.

Ask Vaani to modify or create new agents…
Do your customers have to keep giving context every call?
That's a lot of friction.
Not anymore. Launching Memories.
- Now retain context across multiple calls. Just tell us the number of calls the agent should refer to.
- Define your custom filter — “I want to refer past calls for this order ID only.”
- Want your agent to have context from past calls with a different agent? We offer that too.
Automated call screening leading to connectivity issues?
Solved!
- Zero call drops from call screening agents on the phone.
- The voice agent answers the screener with the name, company, and the reason for the call.
- Once the customer takes the call, the agent introduces itself again and starts the real conversation.
Let's build the world's speech modelling & infrastructure layer together.
