Livea real call, drawn as terrain

    Every missed call is a place on the map. Vera answers there.

    Cervana builds voice agents on its own speech, language and voice models. They answer, book, look things up in your systems and hand over to a person. In our EU cloud, or entirely on your servers. 23 languages.

    Station 01

    The line rings. Nobody picks up.

    Voice AI was sold as a chatbot with a voice. Here is what that looks like from the caller’s side.

    Green: answered and handled. Red: rang out. Nobody rings back.

    • Most voice AI can talk. It can’t do.

      It answers nicely and then tells the caller someone will get back to them. Nothing is booked, nothing is looked up, nothing changes in your systems.

    • It is stitched together from rented models.

      Speech from one US vendor, the brain from another, the voice from a third — every call leaves the country, and a price change or outage upstream is yours.

    • And it only lives on the phone.

      Your customers, students, patients and staff also talk to screens, apps and headsets. The agent that trains your team should be the same one that answers your line.

    Station 02

    A voice picks up, and gets it done.

    Unedited, from production. Read one call as it happened, then listen to two more. No scripts, no cherry-picking.

    Station 03

    It acts while the caller is still on the line.

    A Cervana agent carries tools, not just a script. The call you just read, second by second: what was said, and what got done in between.

    • Books

      Checks free slots and books, moves or cancels appointments — in Cervana’s calendar or straight into yours.

    • Looks up

      Answers from your documents, your website and your own systems, live, mid-sentence.

    • Acts in your systems

      Through MCP and webhooks it reads live stock, creates records, triggers your workflows.

    • Hands over

      Transfers to the right person by department and opening hours; outside hours it takes the callback.

    • Sends

      E-mails a code, a confirmation or a summary while the conversation is still going.

    • Calls out

      Runs outbound follow-ups and campaigns, with disclosure and do-not-call handling built in.

    • Spells and verifies

      Reads names and numbers back letter by letter — including č, š and ž — and corrects itself.

    • Switches language

      Follows the caller across 23 languages the moment they switch, with the same voice.

    • Writes it down

      Every conversation lands as a transcript, a summary and structured records, pushed to your systems as events.

    Everything on the line, in one product.

    Inbound and outbound, phone and web, the studio tools and the on-premise install — all metered on one credit balance.

    • Inbound voice agents

      Answer every call, 24/7, on your own numbers or your existing SIP trunk. Transfer to a human, look things up, take booking requests, end the call cleanly.

    • Outbound calling

      Appointment reminders, follow-ups, and business outreach. Consent-attested, paced to your plan's line count, with AI disclosure spoken on every call and do-not-call honoured permanently.

    • Web widget

      The same agent on any website with one script tag, locked to your origin. No phone number required.

    • Your systems, mid-call

      Point the agent at a lookup webhook, or connect your own MCP server so it can use your tools while the caller is still on the line.

    • Website grounding

      Point the agent at your site and it answers from your own published wording — including JavaScript-rendered pages.

    • Call recordings

      Every call recorded, playable and downloadable in the console, alongside the full transcript.

    • Voice cloning

      Clone a voice with Cervana Melo — documented speaker consent required, always, with no exceptions.

    • Cervana Studio

      The same models as creator tools — generate and clone voice, dub a script into another language, and turn audio into subtitles that keep their timings.

    • On-premise and air-gapped

      The same product, self-hosted on your own hardware. No outbound AI calls to make an exception for, because there are none.

    Booking requests are captured and logged for human follow-up — the agent does not write to your calendar on its own. Full API reference and guides at docs.cervanaai.com.

    It runs where your data already lives.

    Speech recognition, the language model and the voices are Cervana’s own, so nothing is handed to a third-party AI company — ever. The whole stack is ours, so it can run entirely on yours.

    Built for the buyer who has to answer for it.

    The hard part of voice AI in a regulated business is not the conversation — it is proving where the data went. Because every model in the pipeline is ours, that answer is short.

    Station 05

    Six voices already on the route.

    Six things running on Cervana today, in six different places. The phone line is one of them.

    • Phone line

      The receptionist that acts

      Practices, dealers, offices and public bodies: calls answered, appointments booked, names spelled right, every request routed to the right desk — 24/7.

    • Bank, internal

      The training partner

      A bank’s new advisors practise client conversations against an agent that plays the customer, swaps roles, grades the talk — and learned the bank’s own handbooks from PDFs.

    • Therapy practice

      The companion between sessions

      Therapists give clients a voice to talk to between appointments: check-ins, follow-ups and exercises, with the practice’s own guidance and limits.

    • Course platform

      The tutor

      An education institute teaches its courses through a voice that explains, questions and corrects — in the learner’s language, at the learner’s pace.

    • VR environment

      The voice in the headset

      In a VR learning environment, Cervana gives the characters a voice that listens and answers in real time — over the same API that powers the phone.

    • Studio

      The content studio

      Creators and teams generate speech in consented cloned voices, transcribe and subtitle, and dub a script into another language — in one flow.

    Partnership signed July 2026

    Cervana AI is partnering with Odoo.

    Our voice AI is coming to the Odoo Marketplace in September 2026 — production-grade voice and phone agents, one click away, inside the ERP millions of businesses already run on.

    Your CRM, helpdesk, telephony, and contact centre — with an agent that answers, qualifies, books, and follows up natively. No rip-and-replace, no six-month integration project.

    Odoo runs in more than 16 million businesses. The self-hosted option applies here too, like everything else we ship.

    1. Step 1

      Build the agent.

      Give it a role, a voice and what it knows: your website, your documents, your rules. A receptionist, a trainer, a tutor, a companion — same console.

    2. Step 2

      Give it actions.

      Calendar, transfer directory, e-mail, your own systems through MCP, webhooks for every event. Switch each one on; the agent uses them mid-conversation.

    3. Step 3

      Put it anywhere.

      Your phone number or PBX, a widget on your website, your app, a VR environment or a course platform through the API. Cloud, or inside your own data centre.

    Questions people ask first.

    What it is, what it does, what it costs and where your data lives — straight answers from the people who build it.

    What is Cervana AI?

    Cervana AI is a voice AI company. It builds voice agents on its own speech recognition, language and voice models — agents that hold a real conversation and act during it: they book, look things up in your systems, transfer, send e-mails, place outbound calls and write everything down. The same agent runs on a phone line, on a website, inside an app, in a VR environment or a course platform through the API, in 23 languages, in Cervana's EU cloud or entirely on the customer's own servers.

    What can a Cervana agent actually do during a conversation?

    As shipped today: check availability and book, move or cancel appointments (in Cervana's calendar or yours); look up answers in your documents, your website and your systems; act in your systems through MCP and webhooks; transfer to a person by department and opening hours or take a callback; e-mail a code or confirmation; run outbound calls with disclosure and do-not-call handling; spell names and numbers back letter by letter; switch language mid-call; and deliver a transcript, a summary and structured records of every conversation.

    Is Cervana only for phone calls?

    No. Phone lines and PBX integration are one deployment. The same agent answers on a website widget and inside apps, and the Cervana API (speech-to-text, conversation, text-to-speech) powers voices in VR learning environments, course platforms and content tools. Customers use it as a receptionist, as a training partner for bank staff, as a follow-up companion between therapy sessions, as a tutor, as a voice for VR characters and, through Cervana Studio, for dubbing and voice generation.

    Can the agent use our own systems?

    Yes. Connect your systems through MCP and the agent reads and writes them during the conversation — live stock, customer records, bookings. Webhooks deliver every event (call ended, booking made, request recorded) to your software, and your documents and website become its knowledge base.

    How much does Cervana cost?

    Plans start at $9.99 a month (Starter: about 83 call minutes and one line). Standard is $229 a month for 1,000 voice minutes and 2 simultaneous calls; Growth ($549) and Scale ($799) add more minutes, more lines and a lower price per minute. Installation on your own servers is quoted per project. All plans include every language, voice and tool.

    Can I keep my existing phone number?

    Yes. Forward your existing number to Cervana, or connect your phone system over SIP. You can also take a new number, or put the voice agent on your website so visitors can talk to it in the browser.

    Do callers know they are talking to an AI?

    Yes. The agent introduces itself as a digital assistant, which the EU AI Act requires for AI systems that talk to people. Most callers simply appreciate getting an answer straight away instead of waiting on hold.

    What languages does Cervana speak?

    23 languages: English, German, Arabic, Slovenian, Urdu, Spanish, French, Italian, Portuguese, Dutch, Danish, Swedish, Norwegian, Finnish, Greek, Polish, Russian, Turkish, Hindi, Malay, Japanese, Korean and Chinese. When a caller switches language mid-call, the agent switches with them.

    Can it book appointments into my calendar?

    Yes. It books into Cervana's built-in calendar or directly into your own systems through an integration, checks free slots during the call and confirms the time with the caller. Calls, bookings and messages all appear in your console with a full transcript.

    How long does setup take?

    A basic receptionist is live the same day: describe your business, add your website or documents, and connect a number. Projects with your own phone system, calendar or CRM integration typically take one to two weeks.

    Is Cervana GDPR-compliant?

    Yes. Cervana's cloud runs in an EU data centre in Frankfurt and call data does not leave the EU. Speech recognition, the language model and the voices are Cervana's own, so no call is passed to a third-party AI company. A data processing agreement (Art. 28 GDPR) is part of the contract, and audio recording is optional.

    Does Cervana send calls to OpenAI, ElevenLabs or other AI APIs?

    No. Speech recognition (Cervana Percept), the language model (Cervana Noema) and the voices (Cervana Melo) are Cervana's own models and run on Cervana's or your infrastructure. No call audio or transcript is sent to an external AI service.

    What is on-premise voice AI?

    On-premise voice AI is voice AI that runs on the customer's own servers — hardware in their data centre or machines in their private cloud — instead of the vendor's cloud. Speech recognition, the language model, the voices and the call logs all run inside the customer's network. Cervana runs on-premise as well as in its EU cloud: the same software, configured for where it runs.

    What is sovereign voice AI?

    Sovereign voice AI is voice AI where the organisation keeps full control over where its call data is processed and who can access it — typically by running the whole system in its own country or its own data centre, without depending on foreign AI providers. Cervana is sovereign by design because every model in it is its own and it can run entirely on the customer's infrastructure, including air-gapped.

    What hardware does Cervana need to run on-premise?

    A standard GPU server in your data centre or private cloud. A single server with one 48 GB GPU runs a deployment for one language and several simultaneous calls; more lines and languages scale out with more GPUs. We size the installation to your call volume and languages.

    Is Cervana suitable for banks and the public sector?

    Yes — it is built for organisations that cannot send call data to third parties. Banks, chambers, public bodies and healthcare providers run it on their own infrastructure with no outbound connection to AI services, keep transcripts under their own retention rules, and decide who has access. For UAE and Gulf institutions this is how CBUAE and PDPL data-residency requirements are met.

    End of the route. Your turn to call.

    No forms, no sign-up. Allow your mic and talk to a live Cervana agent in English, German, Arabic or any of 23 languages. Then build your own — from $9.99 a month, or entirely on your servers.
