Voice Agent Hosting
Self-Host ASR + LLM + TTS Voice Agent Pipelines — Sub-Second Latency, No Per-Call Fees
Deploy fully self-hosted voice agents on dedicated UK GPU servers. Run Whisper, an open source LLM, and a TTS model in a single low-latency loop — replacing stacked API fees from Twilio, ElevenLabs and OpenAI with flat monthly pricing and complete data privacy.
What is Voice Agent Hosting?
Voice agent hosting means running an entire conversational AI pipeline — speech-to-text (ASR), a large language model (LLM) for reasoning, and text-to-speech (TTS) for spoken output — on your own dedicated GPU server instead of chaining together multiple cloud APIs.
With a GigaGPU dedicated GPU server you get a full GPU card, NVMe storage, and bare metal UK infrastructure. Deploy Whisper for transcription, an open source LLM like Llama 3 or Mistral for reasoning, and Kokoro TTS or Chatterbox TTS for natural speech output — all on a single GPU with sub-second end-to-end latency.
Voice agents built on open source models are now production-ready. Teams are replacing stacked per-minute API costs from providers like Twilio, Deepgram, ElevenLabs, and OpenAI with a single flat-rate server that handles the entire pipeline privately.
Built for private voice agent hosting — not shared-cloud API queues.
The Voice Agent Pipeline
A voice agent combines three models in a real-time loop. All three run on a single GPU server — no external API calls, no stacked latency.
1. ASR
Whisper / Faster-Whisper converts caller speech to text in real time
2. LLM
Llama 3, Mistral, or Qwen reasons over the transcript and generates a response
3. TTS
Kokoro TTS, Chatterbox, or XTTS-v2 speaks the response back to the caller
Loop
The cycle repeats — continuous conversation in real time
Models for Voice Agent Pipelines
Mix and match ASR, LLM, and TTS models to build the voice agent stack that fits your use case. All run on a single GigaGPU dedicated server.
Speech-to-Text (ASR)
Large Language Models (LLM)
Text-to-Speech (TTS)
Any combination of ASR + LLM + TTS models can be deployed depending on GPU memory and latency targets. See Speech Model Hosting for the full speech model list, and Open Source LLM Hosting for all supported LLMs.
Best GPUs for Voice Agents
Voice agent stacks need enough VRAM to fit ASR + LLM + TTS simultaneously, and enough compute for sub-second latency. Here are our top picks.
24GB Ampere fits Faster-Whisper (~3GB) + a 7B LLM at Q4 (~6GB) + Kokoro TTS (~1GB) comfortably. The go-to GPU for teams deploying their first production voice agent on a budget.
Blackwell 2.0 delivers the fastest end-to-end voice agent loop. 32GB GDDR7 fits a 13B LLM alongside ASR and TTS with headroom for concurrent callers. The best choice for production telephony.
96GB unified memory lets you run a 70B LLM alongside Whisper and TTS — ideal for voice agents that need the most capable reasoning model available, such as complex customer support or advisory bots.
Voice Agent Hosting Pricing
Fixed monthly pricing for the full GPU. No per-minute fees, no stacked API charges. Voice agent stacks typically need 24GB+ VRAM — but lighter pipelines can start on 16GB.
Voice Agent Costs: Stacked APIs vs Self-Hosted
Most voice agent providers charge per minute across every layer — ASR, LLM, and TTS fees stack up fast. A self-hosted GPU replaces all three with a single flat monthly rate.
Stacked API Pricing
Self-Hosted GPU
Example: 10,000 Voice Agent Calls/Month (3 min avg)
API cost estimates are based on publicly listed pricing at time of writing and are indicative only. Actual savings depend on call volume, model choices, and provider tiers. GPU server prices retrieved live from the GigaGPU portal.
Why Self-Host Voice Agents Instead of Using APIs?
Stacking third-party APIs for ASR, LLM, and TTS creates compounding costs, latency, and data exposure. Self-hosting the full pipeline on one GPU eliminates all three.
Eliminate Stacked Per-Minute Fees
Cloud voice agents charge per minute on every API layer — ASR, LLM, and TTS fees compound on every call. A dedicated GPU runs the entire pipeline for a flat monthly rate regardless of call volume.
Lower End-to-End Latency
Every external API hop adds 100–300ms of round-trip latency. Running ASR → LLM → TTS on the same GPU eliminates network hops entirely, achieving sub-second response times for natural conversation flow.
Complete Data Privacy
Call audio, transcripts, and conversation logs never leave your server. No third-party data processing agreements needed. Essential for healthcare, legal, financial services, and any industry with strict data residency requirements.
Full Pipeline Control
Choose your own ASR model, LLM, TTS voice, and orchestration framework. Swap components, fine-tune models, adjust prompts, and customise voices without vendor lock-in or API limitations.
Predictable Scaling
API costs scale linearly with every call — budgets become unpredictable. With a dedicated GPU, scaling means adding another server at a known monthly cost, not watching per-minute charges multiply.
No Vendor Dependency
If your ASR, LLM, or TTS provider changes pricing, rate limits, or discontinues a model, your voice agent breaks. Self-hosting gives you complete independence from third-party roadmaps and outages.
Voice Agent Use Cases
From customer support bots to healthcare triage — dedicated GPU servers power every type of voice agent deployment.
Customer Support Voice Bots
Handle enquiries, bookings, returns, and FAQs with a self-hosted voice agent that runs 24/7. Combine Whisper for ASR, an open source LLM for reasoning, and Kokoro TTS for natural-sounding responses — with no per-call API fees.
Telephony & IVR Automation
Replace rigid IVR phone trees with intelligent voice agents that understand natural language. Route calls, collect information, and resolve issues — all powered by your own GPU with sub-second latency.
Appointment Scheduling Agents
Automate appointment booking, rescheduling, and reminders by voice. The LLM checks availability, handles conversational back-and-forth, and confirms bookings — running entirely on private infrastructure.
Healthcare Triage & Patient Intake
Deploy privacy-focused voice agents that handle patient intake, symptom screening, and appointment triage. Call audio and health data stay on your server — never processed by a third-party API.
Real Estate & Property Enquiries
Let potential buyers and tenants call in, ask questions about listings, schedule viewings, and get property details — all handled by a voice agent connected to your property database.
Legal Intake & Client Screening
Automate initial client intake calls for law firms. Collect case details, screen for conflicts, and route qualified leads — with all call data and transcripts kept on private UK infrastructure.
Order Tracking & E-Commerce
Let customers check order status, process returns, and get product recommendations by voice. Integrate with your order management system via API for real-time responses at no per-call cost.
Deploy a Voice Agent in 4 Steps
From order to live voice agent in under an hour. Full root access means you control the entire stack.
Choose a GPU
Pick a server with enough VRAM for your pipeline. 24GB (RTX 3090) is the sweet spot for most voice agents; 32GB (RTX 5090) for production telephony.
Install Your Models
SSH in and install your ASR, LLM, and TTS models. Use pip install faster-whisper, ollama pull llama3, and your chosen TTS framework.
Wire the Pipeline
Connect ASR → LLM → TTS in a loop using a framework like LiveKit, Pipecat, or your own FastAPI orchestration. Expose a WebSocket or SIP endpoint.
Connect & Go Live
Point your SIP trunk, Twilio number, or web client at your server. Your voice agent is live — handling calls on your own private infrastructure.
