Building Ultra-Fast Voice Agents (via)

Experience a voice agent with ultra-fast voice-to-voice response time. Using the Pipecat framework, WebRTC, and Nemotron Speech ASR, we demonstrate a real-time conversational AI with virtually zero perceptible lag. Why this matters: Traditional AI agents suffer from immersion-breaking delays. By optimizing the entire stack—from Nemotron Speech ASR (17ms final transcription) to Nemotron 3 Nano LLM (112ms TTFT) and NVIDIA Magpie TTS (111ms TTFB)—we’ve achieved a production-ready architecture for seamless digital assistants.
