Vapi is a specialized infrastructure platform for building Voice AI agents.[1] It acts as the "orchestration layer" that sits between your LLM (like GPT-4), your Transcriber (like Deepgram), and your Synthesizer (like ElevenLabs). Building a voice bot from scratch is incredibly difficult due to latency and interruption handling. Vapi solves this by providing a pre-built "Turn-Taking" engine that knows exactly when the user has finished speaking versus when they are just pausing. It handles interruptions gracefully. For developers, Vapi removes the headache of stitching together different APIs. It provides a single dashboard to deploy phone-calling bots that can book appointments, handle support queries, and execute functions in real-time.
