I need a fully local, speech-to-speech AI receptionist that can receive phone calls on Windows and or Linux machines without relying on any external cloud calls/subscriptions. The assistant must be able to listen to callers, understand their intent, speak back naturally, and—most importantly—handle two core tasks for me: • Answer customer inquiries in real time for the serivces i provide • Schedule appointments directly into a calendar or booking system design considerations, hardware requirements as well as training and setup guidance (I will build the hardware myself and learn and understand the software design). A smooth pipeline—speech-to-text, intent recognition, response generation, and text-to-speech—is essential; you’re free to choose the stack (e.g., Whisper, Vosk, local LLMs, Rasa, Piper-TTS, etc.) so long as everything runs offline on both Windows and Linux. Deliverables • Source code and install scripts for the complete local stack • An easy way for me to add or edit FAQs and booking rules • Demonstration of the system running on a Windows workstation and a Linux SBC/VM, showing it can field the inquiries above and book an appointment successfully Once tested on my side, I’ll handle enclosure, mics, and speakers; you just ensure the software is sturdy, latency is low, and voices sound professional. preffer someone who has does this before for self hosting AI gents and local LLMs explain and provide tutorials

Your phase-one receptionist will run entirely on-premise: receive SIP/PBX calls, transcribe speech locally, identify the caller’s service question or booking request, generate a grounded response from your approved FAQs, and speak naturally without cloud AI calls or subscriptions. Callers will also be clearly informed they are speaking with an automated assistant. I will build a portable Windows/Linux stack using Docker where appropriate: faster-whisper or Vosk for STT, a local LLM (Ollama/[login to view URL]) with retrieval over editable FAQ and service files, Piper for low-latency TTS, and Asterisk or FreeSWITCH for SIP call handling. Booking rules will be maintained in simple files/admin screens and appointments can be written to a local CalDAV calendar or an adapter for your existing booking system. I will include install scripts, architecture/hardware guidance, recorded setup tutorials, and demonstrations on Windows plus Linux VM/SBC. I have delivered a Raspberry Pi + PlutoSDR kiosk, so I understand the practical constraints of deploying reliable software on edge hardware. For natural, low-latency local conversation, I will size the STT/LLM model to your available GPU or CPU rather than overpromise performance on an SBC. What GPU model (if any) will the Windows workstation and Linux SBC/VM have? Muhammad Saad

Hello, Building a fully offline speech AI receptionist that actually works on commodity hardware is rare—most people either cloud-lock themselves or chase vaporware. You've clearly thought through the stack options and hardware constraints, which tells me you're serious about this. The real question: are you looking to deploy this as a single-machine solution first, or do you need it to scale across multiple locations down the road? We've spent 14 years shipping custom software for logistics, CRM, and SaaS platforms—including systems that process real-time data and handle complex workflows offline. Local AI agents and self-hosted LLM pipelines aren't new territory for us. We'll architect the speech pipeline, wire up your FAQ system so you can edit it without touching code, and make sure appointment booking syncs cleanly to your calendar. Both Windows and Linux will run identical logic; we'll test on actual hardware before you take it. The budget and timeline shown here are starting points—we'll nail down the real scope once we talk through your call volume, response latency targets, and how many concurrent calls you're handling. Let's hop on a quick call to map out the stack and hardware specs. Send me a time that works. Regards, Nurul Hasan

Hello!, I am a US-based senior software engineer and I’d love to help build your fully local, speech-to-speech AI receptionist for Windows and on-premise use. The main challenge here is not just speech output, but making the system reliably answer calls, understand intent quickly, and stay fully offline with no cloud dependency. I’d approach it in phases: first confirm the call flow and hardware/audio setup, then build the local speech pipeline, connect VoIP/call handling, and finally test for latency, accuracy, and edge cases. I can help with: 1. Local speech recognition and TTS on-premise 2. VoIP/phone call integration on Windows 3. Receptionist logic for routing, FAQs, and message capture 4. Audio tuning to reduce lag and recognition issues 5. Clear call logs and reliable handoff behavior I pay close attention to the details that make these systems actually work in production, not just in demos. If needed, I can also recommend the best local model and deployment setup for your budget and hardware. Could you please clarify the following questions to help me better understand the project? 1. What phone system or VoIP provider should this connect to, or do you need that built as well? 2. Should it only answer and route calls, or also handle booking, FAQs, and message taking? 3.

The difficult part isn't simply running a local LLM-it's making telephony, speech recognition, reasoning, speech synthesis and appointment booking work together in real time with low latency and no cloud dependency. I'd structure this as modular, fully self-hosted services: SIP/telephony -> local STT -> intent/RAG knowledge layer -> local LLM -> local TTS -> booking adapter. This keeps the system maintainable and allows individual components to be upgraded without rebuilding everything. I'd start by validating the call path and hardware targets on both Windows and Linux, then build the core conversation loop before adding scheduling. For FAQs and services, I'd use an editable local knowledge base so you can update answers and booking rules without retraining the model. One important consideration is caller interruption: the system needs barge-in, silence detection and reliable conversation state management so it can handle natural speech without talking over callers or losing context. Which SIP provider, PBX or phone hardware will receive the calls? Should the booking system also remain fully local, or may it connect to an external calendar? What hardware are you planning for the Linux target? I can provide source code, install scripts, setup guidance and practical tutorials so you can understand and maintain the system yourself.

Hi, Your project to build a fully local speech-to-speech AI receptionist for Windows and Linux aligns with my experience in architecting offline, low-latency audio processing and LLM orchestration systems. The main technical risk is ensuring reliable telephony integration and real-time intent recognition without cloud dependencies. I led development on the AI Translator Plugin, which delivered real-time offline speech recognition and synthesis with low latency on macOS, a close parallel to your cross-platform requirements. Additionally, my work on the DocIntel AI platform involved designing scalable AI pipelines and backend services that can be adapted for intent recognition and response generation. I typically design systems by separating the audio ingestion, intent recognition, and response synthesis layers to isolate and optimize each stage. Early validation of the telephony interface and scheduling integration will be key to system reliability. To ensure production readiness, I recommend implementing confidence thresholds and fallback handling to maintain smooth interactions and minimize unsupported responses. I can start by outlining the audio processing and intent recognition pipeline architecture to align on key interfaces and extensibility. Thanks, Clifton

Hi, I'm Denis. I've built local voice agents before, including a speech AI receptionist that handled appointment booking entirely offline on both Windows and Linux. The system used Whisper for speech-to-text, a local intent model for understanding queries, and Piper-TTS for natural responses, all running on a low-power mini PC with a USB mic and speaker setup. For your project, I'd structure it in three phases: first, integrate Whisper for reliable offline speech recognition, then implement a local intent classifier trained on your FAQs and booking rules, and finally connect Piper-TTS for voice output. The core will run as a service that interfaces with your calendar API or a simple local database for scheduling. I'll include a config file for FAQs and rules so you can edit without touching code, and provide install scripts plus a short tutorial covering hardware choices, noise reduction settings, and latency tuning. The main risks are background noise affecting speech quality and ensuring the intent model scales with your FAQs. I'd handle noise by adding a simple VAD filter and multi-channel audio processing, and keep the intent model lean so it runs fast on modest hardware. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

Hi there, I can build a fully self-hosted speech-to-speech AI receptionist designed to run locally on both Windows and Linux without depending on cloud AI subscriptions or external inference services. I would structure the system as a modular pipeline: local speech-to-text → intent/context processing → local LLM response generation → local text-to-speech, with the telephony/VoIP layer connecting incoming calls to the agent. Technologies such as Whisper or Vosk, a suitable local LLM runtime, and Piper-TTS can be evaluated based on your available hardware and the latency/voice-quality requirements. The receptionist can be configured around your actual services and FAQs, with a straightforward knowledge/configuration layer so you can update answers and booking rules without modifying the core application. For appointments, I would implement a controlled booking workflow that checks availability, collects the required caller information, confirms the appointment details, and writes the booking to the selected calendar/booking system. Along with the source code and installation scripts, I can provide detailed setup documentation covering hardware recommendations, model installation, configuration, FAQ management, booking configuration, troubleshooting and deployment. I would also demonstrate the complete call → conversation → appointment workflow on both target environments. Looking forward to working with you. Thanks.

You're trying to add AI into a On-Premise Speech AI Receptionist where the real challenge is making the AI layer reliable and the prompts survive real-world use. I've handled similar builds involving Wireless, VoIP, Machine Learning (ML), Software Development, usually where the important part was translating the brief into a reliable working system. My approach would be to first define the input schema, generation rules, and output validation, then build the workflow around those controls so AI output stays consistent. For this project, I would focus especially on: - Input workflow design, prompt/control rules, and output validation - Backend processing, file/document generation, and dashboard usability - Scalable cloud structure, API boundaries, and error handling If helpful, I can map the input-to-output workflow and where validation should sit before implementation.
