Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.

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.
