Thanks — I understand you need to show a live, low-latency voice calling agent for a short client demo using free resources. Below is a clear, step-by-step plan you can follow quickly. Quick summary of the approach • Use LiveKit Cloud’s free tier for short demos. • Build the agent in Agent Builder (no-code) and deploy instantly. • Use LiveKit Inference (co-located model routing) for low latency STT/LLM/TTS. • Optionally attach the free US phone number to demo inbound calls. Step-by-step guide 1. Create a free LiveKit Cloud account • Sign up for the free tier (no credit card). The free account includes session minutes suitable for short demos. 1. Build the voice agent with Agent Builder (fast, no-local-setup) • Open Agent Builder in your browser and create the agent flow and voice settings. • Use the built-in preview to test interaction in real time. • Agent Builder uses the same production voice pipeline, so your demo will reflect live behavior. • When ready, click Deploy agent to go live instantly. 1. Ensure low latency • Deploy on LiveKit Cloud so the agent and inference services are co-located; this minimizes network hops and reduces latency. • Use LiveKit Inference for STT, LLM, and TTS so speech and model calls run through provisioned, low-latency connections. • Before the demo, run a few test calls and measure Time To First Token (TTFT) / Time To First Byte (TTFB) in the observability tools to confirm responsiveness. 1. (Optional) Enable phone calling for the demo • You can use the one free US local phone number included in the plan. • Attach a dispatch rule to route inbound calls to your deployed agent so the client can call a phone number rather than use the browser. 1. Test and prepare fallback options • Test with colleagues from different networks to confirm latency and audio quality. • Have a backup demo plan: a recorded session of the live agent or a short local demo using the preview mode in case network conditions degrade. What I can help with next • Walk you through Agent Builder: I can guide you step-by-step in the builder UI. • Help configure a dispatch rule and attach the free phone number. • Run a quick checklist to validate latency metrics before your demo.
