Vinis: Sovereign Voice AI for Recorded and Regulated Conversations
Vinis runs voice interactions on-prem under MiFID II and FCA call-recording duties, so transcripts and voice biometrics never leave the firm.
The voice problem nobody wants to name
Every regulated firm records calls. Banks, brokers, insurers, advisers and contact centres are required to. Under MiFID II, firms must record telephone conversations and electronic communications that relate to transactions, keep them for at least five years, and produce them to the regulator on request. The FCA layers its own call-recording obligations on top, covering retail and wholesale activity alike. The recordings are not optional. They are evidence.
So here is the uncomfortable question. If you record every call, where does the audio go when you want to do something useful with it? Transcription, sentiment analysis, compliance scoring, vulnerable-customer detection, agent quality monitoring, voice authentication. Almost every off-the-shelf voice AI sends that audio to a public-cloud endpoint. The moment it leaves your building, you have shipped special-category data, voice biometrics and customer conversations to infrastructure you do not control, often across a border, frequently within reach of the US CLOUD Act.
That is the gap Vinis closes. Vinis is the voice subsystem of Mickai, the sovereign AI operating system. It handles speech-to-text, voice analytics, voice biometrics and conversational AI entirely inside your own walls, on-prem and air-gapped, with every action written to a tamper-evident, post-quantum-signed audit record. The audio never leaves. The transcripts never leave. The voiceprints never leave. This is built and live, not a concept.
What Vinis actually does
Vinis is not a transcription API with a privacy badge bolted on. It is a full voice stack that runs where your recordings already live.
It transcribes recorded and live calls, including UK and international accents, financial terminology and overlapping speech. It diarises who said what. It runs sentiment and risk scoring across a conversation so compliance teams can triage the calls that matter instead of sampling blind. It performs voice biometric enrolment and verification for caller authentication, keeping every voiceprint inside the firm rather than in a vendor's identity cloud. And it can drive live conversational agents that answer, route and resolve, with the same on-prem boundary applied to every word.
Crucially, none of this is a hosted service you phone home to. Vinis is software that regulated businesses own and run themselves, the same way Mickai runs every other capability.
Why on-prem is the whole point
The promise of cloud voice AI was convenience. The cost, for a regulated firm, is loss of control over the most sensitive data it holds. Voice is biometric data. Under UK GDPR it is special-category data, and a voiceprint is as identifying as a fingerprint. Call content routinely contains payment details, health disclosures, financial circumstances and evidence of vulnerability.
When that data moves to a third-party model, three things happen at once. You create a cross-border transfer problem. You hand a copy of customer biometrics to a processor you cannot fully audit. And you expose the firm to legal-access regimes, including the US CLOUD Act, that can compel disclosure regardless of where you thought the data sat.
This is the wedge Mickai is built for. Roughly 850,000 UK businesses, around 15 percent of the total, sit under rules that make sending data to public-cloud AI legally difficult or impossible. Across the EU the figure is closer to five million. The pressures are stacking: PRA SS2/21 on model risk, UK GDPR special-category handling, the NHS DSP Toolkit, the EU AI Act's high-risk classifications, ITAR and EAR, the NIS Regulations. The sovereign AI market sized at USD 40 billion in 2025 is forecast to reach USD 148 billion by 2032. Vinis is the voice answer to that demand.
Run on-prem, the calculus inverts. The audio stays on the firm's hardware. The model runs against it locally. The regulator can be shown not just the output but a signed, tamper-evident record of every inference, every access and every redaction. Sovereignty stops being a slogan and becomes an architecture.
The audit record changes the conversation with the regulator
Recording a call satisfies the letter of MiFID II and FCA rules. It does not, on its own, prove what was later done with that recording. Who transcribed it, what model scored it, who accessed the voiceprint, whether anything was altered.
Every Vinis action writes to the Mickai OAR, the tamper-evident, post-quantum-signed audit record that runs across the whole operating system. That means a transcription, a biometric match, a sentiment score and a redaction are each captured as a signed, append-only event. When the FCA, an internal audit team or a litigation request asks what happened to a given call, the firm produces a cryptographic chain of custody rather than a verbal assurance. For voice data, where the dispute is often about exactly what was said and what was done with it, that record is the difference between an assertion and proof.
Where Vinis sits in the wider system
Vinis does not stand alone. It is one voice subsystem inside Mickai, alongside the Greek-named Studio modules that handle specific regulated functions: Nemesis for fraud and AML, Nomos for compliance, Iris for customer service, Astraea for legal, Panacea for clinical work, Aletheia for audit. A call transcribed and scored by Vinis can flow into Nemesis for AML signal detection or Iris for service quality, all within the same sovereign boundary and the same audit record. The firm assembles the capabilities it needs without ever opening a door to the public cloud.
Mickai LTD holds 104 filed UK patent applications, roughly 2,340 claims, with Micky Irons as inventor. These are filed, not granted, which establishes priority and a substantial prior-art position around sovereign, audited, on-prem AI. As a dated third-party signal, in June 2026 Micky Irons was verified live at number four on Crunchbase's CB Rank for people, with the Mickai company profile in the top one to two percent globally. We treat that as a June 2026 momentum marker, not a permanent claim, and we are building to scale from it.
An ally, not a replacement
Mickai is not positioned against the frontier labs. For the vast majority of workloads, public-cloud AI is the right tool and we say so. The dual-buyer thesis is simple. Use the best public models where the data permits, and run Mickai where the law does not. Vinis exists for the calls a regulated firm legally cannot send anywhere else. That is a complement to the wider AI market, not a war against it.
The opportunity
Mickai is a UK company with Birmingham manufacturing secured, and Vinis is built and live as part of the operating system, not a roadmap promise. As we scale, a pre-seed window is open to a selected group of partners who want to be involved early in sovereign AI for regulated voice. This is an invitation to the right partners, not a search for rescue.
If you run recorded or regulated voice operations and the question of where your audio and biometrics actually sit is a live concern, that is the conversation to have. Reach me directly at micky@mickai.co.uk.

Frequently asked questions
What is Vinis?
Vinis is the voice subsystem of Mickai, the sovereign AI operating system. It runs speech-to-text, voice analytics, voice biometrics and conversational AI entirely on-prem and air-gapped, so audio, transcripts and voiceprints never leave the firm. It is built and live.
How does Vinis help with MiFID II and FCA call-recording obligations?
MiFID II and FCA rules require firms to record relevant calls and produce them on request. Vinis lets firms analyse those recordings inside their own walls, and every action writes to the Mickai OAR, a tamper-evident, post-quantum-signed audit record, giving the regulator a cryptographic chain of custody rather than a verbal assurance.
Why does on-prem matter for voice data specifically?
Voice is biometric and, under UK GDPR, special-category data. Sending it to a public-cloud model creates a cross-border transfer problem, hands customer biometrics to a processor you cannot fully audit, and exposes the firm to legal-access regimes such as the US CLOUD Act. Running on-prem keeps the audio and voiceprints on the firm's own hardware.
Is Mickai trying to replace public-cloud AI?
No. Mickai is an ally, not a replacement. For most workloads public-cloud AI is the right tool. The dual-buyer thesis is to use the best public models where the data permits and run Mickai where the law does not. Vinis exists for the calls a regulated firm legally cannot send anywhere else.
How can a partner get involved with Mickai?
Mickai is a UK company with Birmingham manufacturing secured and is building to scale. A pre-seed window is open to a selected group of partners who want to be involved early in sovereign AI for regulated voice. You can reach Micky Irons directly at micky@mickai.co.uk.
