Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
Low-latency video, voice and AI-agent APIs for developers
Drop-in SDKs for Web, iOS, Android, Flutter, and React Native deliver sub-100ms audio/video with active speaker detection, screen share, chat, polls, Q&A, and a pre-call lobby.
Compose speech-to-text, LLM, and text-to-speech providers into an agent pipeline with VAD and turn detection, then run it server-side on VideoSDK's managed infrastructure.
Ship low-latency interactive streams with audience chat, polls, live captioning, RTMP out, HLS for large audiences, and WHEP/WHIP protocol support.
Record composite or per-participant audio and video tracks with custom layouts and encryption, and send files straight to your own S3, GCP, or Azure bucket.
