AI Voice Prompt Engineer (Real-Time Ordering System – NOT Chatbots) Body: We’re building a real-time AI phone agent for restaurants that takes full orders (like a human cashier). This is NOT a chatbot project. We need someone who understands: • real-time voice interaction (low latency) • turn-taking (no awkward pauses) • structured ordering flows (pizza, drinks, modifiers, upsells) • keeping conversations FAST, NATURAL, and ON TRACK What’s broken right now: • AI pauses too long • conversation loops / goes off track • responses feel robotic • ordering flow isn’t tight Your job: • design prompt structure + conversation flow • force clean step-by-step ordering (rails) • eliminate delays + overthinking responses • make it feel like a real employee, not AI Stack: • Twilio (voice + SMS) • ElevenLabs (voice) • OpenAI / LLM backend • n8n automation You are a fit if: • you’ve worked on voice agents (not just chatbots) • you understand latency + response timing • you build short, fast, controlled responses • you’ve done ordering / customer service flows before To apply: Send: 1. Example of a voice or chatbot flow you built 2. How you would structure a pizza order conversation 3. Why most AI voice systems feel slow/robotic Bonus (this filters HARD): If you know what “turn-taking latency” is and how to fix it, you’re exactly who we want.

Hi there, I’ve reviewed your project and understand you’re building a real-time AI phone agent that must handle fast, structured ordering without sounding robotic or losing flow. The core issue isn’t just the model, it’s prompt design, turn-taking control, and latency handling so the system behaves like a trained cashier with tight, predictable conversation rails. I can design a prompt and flow architecture that enforces step-by-step ordering with minimal tokens, controlled responses, and strict state management. For a pizza flow, I’d structure it as: greeting → order intent → item selection → size → crust → toppings → modifiers → upsell → confirmation → payment handoff, with each step locked and validated before moving forward. To fix turn-taking latency, I’d reduce model overthinking using constrained prompts, streaming responses, early partial replies, and tighter n8n orchestration so the agent responds instantly without pauses or loops. I’ll also tune ElevenLabs delivery timing and Twilio handling to keep interactions natural and fast. You’ll get a refined prompt system, optimized conversation flows, and clear logic your team can reuse and scale across menus. I’ve worked on similar AI-driven flows and can quickly stabilize your system to feel human, responsive, and reliable. Let’s connect and I’ll walk you through a working approach.

Hello, Here are answers to your questions: 1. Built a real-time AI voice ordering system using a structured state machine (items, modifiers, upsells, confirmation). Implemented streaming + strict turn-taking for low latency. Added schema validation, retries, logging, and fallbacks for interruptions or unclear input. 2. Pizza flow uses a slot-filling approach. Agent: “What can I get started for you?” (captures item) User: “Large pepperoni.” Agent: “Thin crust or hand-tossed?” (forces modifier) Logic: If any slot is missing (size, crust, etc.), the agent is hard-constrained to collect it before moving to upsells. 3. Why systems feel slow/robotic: It’s usually a mix of high TTFB and "Polite-Bot Syndrome." Most engineers write prompts that make the AI use too many filler words or "Internal Monologue," which increases output tokens and, by extension, latency. Turn-taking latency is the gap between the user finishing a sentence and the AI starting its response. I solve this by adjusting the VAD sensitivity and using "pre-computation" for common confirmation phrases so the audio starts before the full LLM logic is even finished. Looking forward to making your AI agent fast, natural, and truly human-like. Best, Niral

Hi, this is exactly the kind of system I’ve worked on—real-time voice agents, not chatbots. I understand that the core problem here is latency + flow control, not just prompt quality. Most systems feel slow because of turn-taking delays (waiting for full transcripts, long LLM responses, and TTS buffering) and lack of strict conversational rails. I design prompts + orchestration together—forcing short, deterministic responses, early intent locking, and step-by-step ordering flows (item → size → modifiers → confirmation → upsell → close) so the AI stays fast and on track. For a pizza flow, I’d structure it as: greet → capture item quickly → immediately narrow options (size/crust) → confirm → modifiers → upsell → finalize—each step with strict token limits and interruption handling. I also reduce latency by streaming partial responses, using aggressive prompt constraints, caching menu logic, and minimizing LLM “thinking time.” I’ve worked with stacks involving Twilio, voice pipelines, and LLM orchestration, and I focus on making the agent feel like a trained employee—not an AI. Happy to share examples and refine your current flow quickly.

Hi, I’m Karthik with 15+ years of experience in AI systems, real-time applications, and conversational design, and I’ve worked on voice-driven workflows beyond basic chatbots. I understand your challenge—this is about **low-latency, controlled voice flows**, not generic LLM chat. **How I’ll fix it:** ✔ Design strict prompt “rails” for step-by-step ordering (no drift/loops) ✔ Implement fast turn-taking with short, deterministic responses ✔ Reduce latency via streaming responses + pre-emptive prompts ✔ Structure flows: item → modifiers → upsell → confirm → close **Pizza Flow Example (simplified):** “Welcome! What pizza would you like?” → size → crust → toppings → add-ons → drinks → confirm → total → close (Each step locked, no open-ended wandering) **Why AI feels slow/robotic:** • Overly long prompts + reasoning delays • No turn-taking control (waiting too long to respond) • Lack of structured state → AI “thinks” instead of executes **Fix:** • Streaming + partial responses • State machine + prompt constraints • Preloaded intents for instant replies **Stack Fit:** ✔ Twilio, ElevenLabs, OpenAI, n8n – experienced with similar pipelines I focus on making AI sound like a fast, efficient employee—not a bot. Available to start immediately. Warm Regards, Karthik Resonite Technologies

Hi, This is exactly the kind of system I work on—real-time voice agents that need to feel fast, natural, and controlled (not chatbot-style). I’ve built conversational flows where latency, turn-taking, and strict task completion (like ordering) are critical. The main issue in most setups is over-generation + poor flow control, which causes delays, loops, and unnatural pacing. I can help you: • Design a strict, step-by-step ordering flow (no drift) • Reduce latency with shorter responses + better turn-taking control • Eliminate loops and “AI overthinking” • Make responses sound like a fast, real cashier I understand how to balance LLM flexibility with hard rails so the system stays efficient and on-track. Happy to share examples and refine your current setup quickly.

Long pauses and robotic detours are killing orders; I’ve fixed that for restaurant voice agents before. If your system sounds like a hesitant bot, you’re losing revenue on every call. The best thing about me is I’ve worked on a very similar project recently. I built a real-time F&B voice flow for Skallix using Twilio + OpenAI + ElevenLabs with strict rails for menu steps, partial-transcript streaming to cut latency, and barge-in support so customers never wait. I understand the user flow: Twilio call to streaming ASR, incremental LLM intent resolution, immediate short TTS replies, n8n for POS/order routing. Key features are low-latency turn-taking, forced step-by-step ordering (size, crust, toppings, modifiers, upsells), quick confirmations, and graceful agent handoff. Tech stack fits what you listed. I can save time by reusing the prompt templates and timing logic I already built. Quick questions: what’s your target average order time and acceptable silence threshold? Do you require on-call card capture or prefer SMS payment handoff and POS integration details? Happy to chat or jump on a quick call. Regards Ali Zain!!
