I want to roll out an AI receptionist whose single role is to speak with customers and give them clear, accurate information about our products and services. A caller (or site visitor) asks a question, the system turns that speech into text, pulls the correct answer from a knowledge base I will supply, and then replies in smooth, human-sounding audio—no appointment booking, no generic FAQ chatter, just concise product guidance. Here is the scope I have in mind: • Speech-to-text captures the question. • An NLP layer (LLM, Dialogflow, Rasa, or a framework you recommend) matches the query to the right answer. • Text-to-speech returns the response in natural audio, ideally with a custom voice so it feels branded. • The module plugs into either my website chat widget or a phone line; I’m flexible as long as latency stays low and audio quality is crisp. Acceptance criteria – Handles at least 90 % of sample product questions correctly. – End-to-end response time under two seconds. – Audio replies sound natural and welcoming, not robotic. Please tell me which tools or APIs you prefer (Whisper, ElevenLabs, Azure Cognitive Services, etc.), how you’ll ingest and update the knowledge base, and share any voice-AI work you’ve done before. Source code and clear setup notes must be part of the final deliverable so I can host it myself once the project is complete.

Hi there, I am a strong fit for this project because I have built voice-driven AI modules that combine speech recognition, knowledge-base retrieval, and natural audio responses. I have implemented similar pipelines using Whisper or Azure Speech for speech-to-text and ElevenLabs or Amazon Polly for high-quality text-to-speech. I would structure the system with a lightweight Node.js or Python service that processes audio input, queries a knowledge base using an embedding or intent layer, and returns a concise response for audio playback. The knowledge base can be maintained as structured documents or embeddings so new product information can be updated without retraining the full model. I focus on keeping response latency low, logging queries for accuracy improvements, and delivering clear source code with setup instructions for self-hosted deployment. I am ready to review your product knowledge base and outline the architecture and development timeline. Regards Chirag

I’ve deployed several low-latency AI voice agents specifically designed for high-stakes customer interaction, similar to the receptionist role you’re envisioning. My focus is on minimizing response lag to ensure the conversation feels natural, avoiding the "robotic" delays that frustrate callers. Having built voice systems for scheduling and FAQ resolution, I understand how to tune a model’s persona to represent your brand professionally while delivering immediate value to your customers. To ensure this receptionist is responsive and accurate, I propose using Vapi or Retell AI integrated with GPT-4o to achieve sub-second response times. I will implement a robust RAG (Retrieval-Augmented Generation) system or a structured JSON knowledge base so the AI provides precise answers based on your documentation. This setup will include a Twilio telephony layer for seamless call handling and a logic-driven prompt structure that manages interruptions gracefully, ensuring callers feel heard throughout the conversation. I have two questions to refine the scope: do you have a preferred telephony provider, and will the AI need to integrate with a CRM or calendar to push data post-call? I’d be happy to discuss these details or hop on a brief call to align on the technical requirements and show you how we can achieve a truly human-like interaction. Let’s connect to see how we can streamline your customer intake with this AI solution and improve your operational efficiency immediately.

Hi, For a natural sounding AI receptionist I recommend using Vapi because it is designed specifically for voice agents and provides very human conversations with low latency. It works well with models like Whisper for speech recognition and ElevenLabs for natural voice output and usually costs around $0.15 per minute. Vapi can also provide phone numbers so customers can call directly and speak with the AI agent. I can set up the full system so it captures the customer question, retrieves the correct answer from your knowledge base, and responds with smooth natural audio on your website or phone line. I have built similar voice support and booking agents before and can deliver a reliable solution with clean code and simple setup so you can host and manage it easily. Best Regards

Hi, Thanks for the detailed brief — this is right in my wheelhouse. I've built and currently run a production voice bot handling live inbound calls for a 400+ store retail chain, so I know exactly what it takes to hit sub-2s latency with natural audio. For your project I'd use Deepgram Nova-3 for streaming speech-to-text, GPT-4o-mini paired with FAISS vector search for answering (every response grounded in your actual product docs, no hallucination), and ElevenLabs for natural text-to-speech with custom voice cloning for branding. The whole pipeline runs on Pipecat, an open-source voice framework, and connects to both Twilio for phone and a WebSocket widget for web. For the knowledge base, you drop in PDFs, CSVs, or docs and they get embedded into a vector index automatically. Updates mean adding new files — no retraining needed. On your criteria: RAG ensures 90%+ accuracy because answers come from your data, not guesswork. The streaming pipeline runs STT, LLM, and TTS concurrently so typical latency is 700ms–1.2s. ElevenLabs delivers studio-quality audio, not robotic. Deliverables include full Python source, Docker Compose setup, KB upload endpoint, web and phone integration, and setup docs. Working demo in two weeks — share your knowledge base and ~20 sample questions to kick off. Happy to discuss!

Hi, hope you are doing well. My approach is to treat this as a retrieval-first system: speech-to-text converts the caller’s question, then a RAG layer searches your approved documents and generates a concise response with strict “answer only from sources” behavior. For the voice, I’d use a high-quality TTS option such as ElevenLabs or Azure, and keep the voice configurable so you can swap to a branded voice later without code changes. To hit the sub-two-second target, I’ll use streaming STT where possible, pre-built embeddings for the KB, and a small cache for repeated questions. You’ll get a simple admin process to update the knowledge base, re-index, and deploy, plus clear logs showing what sources were used so you can audit correctness. Deliverables include the source code, setup notes, and a working integration for either a web widget or a phone line, with a test harness to measure accuracy against your sample questions. I can start immediately; will your knowledge base be PDFs and web pages, or already structured Q&A, and do you prefer the first integration to be website chat or a phone number? Looking forward to your reply. Best.
