Vaani

What is Vaani?

A voice AI platform and REST API from Bengaluru's Vaani AI Research for building agents that place and answer phone and web calls, use your tools during the call and return the outcome to your app.

Key features

• Teacher AI builds an agent from a plain-language brief, with clarifying questions, a readiness score and a reviewable prompt diff
• Natural turn-taking, filler words, automatic language and dialect switching, and voices with emotional tags
• Memories that carry context across calls with the same caller and between agents
• Call-screening handling, voicemail detection, warm and live transfers
• REST API (cURL, Python, Node.js) to trigger calls, plus call_ended and call_postprocessing webhooks with transcript, summary and extracted fields
• Campaigns with calling hours and retry rules
• Pick your own LLM, TTS, STT and carrier (Twilio or Vobiz), or bring your own keys
