The AI voice agent
that never leaves
the United Kingdom.
Persona is the only voice AI where speech-to-text, the language model and text-to-speech all run inside AWS London. No hops to the US. No third-party LLM calls. UK GDPR compliant by architecture — not just by policy.
Backed by Hostcomm's twenty years of contact centre experience
Where your data actually goes.
Most "UK" voice AI products quietly send audio to OpenAI in Virginia, ElevenLabs in California, or Anthropic in San Francisco. Persona doesn't. Every component runs inside a single AWS region in London — and it's auditable.
Caller speaks
Audio enters via SIP or WebRTC. TLS-encrypted from the first packet.
STT in UK
Speech-to-text runs on UK-hosted models inside the same VPC.
LLM in UK
Open-weights language model in AWS eu-west-2. No external API calls.
TTS in UK
Neural voice synthesis on UK-hosted models. No ElevenLabs.
Caller hears
Synthesised audio returns to the caller. Under 800ms total.
- Data leaving the UK region
- API calls to OpenAI, Anthropic or Google
- Audio sent to ElevenLabs or any US TTS provider
- Reliance on US-based sub-processors
- UK GDPR & EU GDPR compliance by architecture
- Standard DPA available pre-contract
- Optional PII redaction before LLM processing
- PCI DSS Level 1 — Hostcomm certified 5 years running
The paperwork is already done.
Persona arrives pre-cleared for UK procurement. Hostcomm holds every framework, certification, and interconnect that enterprise and public sector buyers ask about — and has held them for years.
G-Cloud 14
Hostcomm is listed on the UK Government's Digital Marketplace under G-Cloud 14, making Persona directly procurable by NHS trusts, local authorities, and central government without a separate tender.
Crown Commercial Service
Hostcomm is an approved Crown Commercial Service supplier. Buyers across central government, the wider public sector, and charities can purchase Persona through CCS-managed commercial agreements.
BT Wholesale Partner
Hostcomm holds a direct interconnect with BT Wholesale — one of very few AI voice vendors with this level of underlying telephony relationship. This delivers superior UK call quality, lower latency, and carrier-grade reliability.
PCI DSS Level 1
Hostcomm is a PCI DSS Level 1 service provider — the highest tier of payment card security certification — for the fifth consecutive year. The PCI discipline is applied across the whole Hostcomm network, not only the card data zone.
ICO Registered
Hostcomm is registered with the Information Commissioner's Office as a data controller and processor. Persona operates under a standard UK GDPR Data Processing Agreement available to prospective customers before contract.

Persona vs everyone else.
We compared Persona against the four voice AI platforms most often shortlisted by UK buyers. None publish a UK-only commitment for their full voice stack. We do.

Sourced from public documentation and vendor trust pages as of April 2026. "Unstated" means the vendor's website does not explicitly commit to a UK-only processing region for that component. We will happily update this table if any vendor publishes a clearer commitment.
Built for sectors that can't compromise.
UK data residency isn't a marketing line for these buyers — it's a hard procurement requirement. Persona is the only voice agent purpose-built to clear it on day one.
Patient data that legally cannot leave the UK.
Appointment booking, prescription enquiries, and out-of-hours triage. Persona keeps every word of every patient call inside the UK boundary — simplifying your DPIA and removing a recurring procurement objection.
FCA Consumer Duty, evidenced automatically.
Persona records, transcribes, and analyses 100% of regulated calls without exporting them to the US. Built-in sentiment, vulnerability detection, and Consumer Duty evidence-gathering workflows.
Sovereign by architecture, not just by promise.
Council tax, housing repairs, parking, benefits enquiries. Persona meets data residency requirements without an exception process, and can be procured through standard frameworks.
Repairs reporting at 3am without a callback queue.
Inbound voice agents triage repairs, log to your housing system via webhook, and warm-transfer emergencies to humans. The same agent runs outbound rent reminder campaigns during the day.
Privileged conversations that stay in the jurisdiction.
Client intake, conflict checks, appointment scheduling. Solicitors' regulation and client confidentiality both benefit when no audio crosses the Atlantic — and Hostcomm provides the DPA pre-contract.
Demand spikes, handled without hiring.
Storm calls, meter reads, smart-meter onboarding. Persona scales from one concurrent call to thousands within the same UK region, with no cold-start latency.
The questions procurement always asks.
These are the questions we hear in every information governance review. The answers are the same in every meeting, so we've put them here in writing.
Ask a different question →All voice data — speech-to-text, the language model, and text-to-speech synthesis — is processed inside Amazon Web Services region eu-west-2, located in London, United Kingdom. No audio, transcript, or derived data leaves the UK at any point in the pipeline.
Twenty minutes. One demo.
Zero data leaving the UK.
Bring your toughest information governance question. We'll show you the architecture, hand over the DPA, and put a live agent on a real phone number — all in the same call.
