Turn detection
Our own model, running locally. It knows the difference between a finished sentence and a caller who is still thinking.
Live — answering calls right now
Your data never leaves. Not even the voice.
Hyperion owns all four layers of the voice stack — turn detection, speech recognition, synthesis and telephony — so the whole agent can run inside your own network.

01The stack
Four layers. All four are ours.
Almost every voice AI vendor rents at least one layer from somebody else. We wrote all four — which is why Hyperion can run with no internet at all.
Speech recognition
Transcription tuned for Turkish first, at 99.6% accuracy — and deployable on your own machines when the data cannot travel.
Speech synthesis
Our own voices — and your brand's voice, cloned from fifteen seconds of a recording, then used across every campaign.
Telephony
Our own Asterisk bridge. Hyperion joins the switchboard you already run — nothing is ported, nothing is replaced.
02How it works
Live in days, not quarters.
Three steps, no IT project. Most businesses are answering calls with Hyperion inside a week.
- 01
Connect
Keep your number. Forward it to Hyperion — or let us provision a fresh line. No hardware, no IT project.
- 02
Compose
We tune the voice, the manners, and the knowledge to your business — your services, your calendar, your tone, your rules.
- 03
Converse
Hyperion answers, qualifies, books, and writes everything to your CRM. When a human should step in, it transfers warmly — with full context.
03Capabilities
Things other agents simply cannot do.
Owning the stack buys behaviour, not just margin. Pick one to see it on a call.
Natural hold
When a caller says “give me a second”, Hyperion goes quiet, waits it out, and picks the sentence back up where it left off.
Call log
00:41Caller: “give me a minute”
00:41Held the line in silence — 58 s
01:39Resumed mid-sentence, nothing repeated
IVR navigation
When the other end answers with an automated menu, Hyperion listens to it, presses the right keys, and gets through to the department it needs.

Live sentiment
The caller's mood is read while they are still speaking, and the call bends to it — shorter, slower, or straight through to a person.

Data filtering
Hand Hyperion a list. It calls every number on it, asks what you need to know, and gives you back only the rows that matched.

Voice cloning
Fifteen seconds of a recording is enough to build the voice your customers already know — then it is the same voice on every call.

Zero data retention
We keep nothing. Recordings and transcripts exist only where you decided they should exist — including nowhere.

04Use cases
One voice. Every customer.
Regulated sectors first, because they are the ones nobody else can serve. Pick one to hear the call.
Caller
“I need to move my appointment.”
Hyperion
“Of course. I have Thursday at 15:30 or Friday at 10:00.”
Appointments, recalls and reminders — with patient data that never leaves the practice.
Caller
“There's a transaction on my account I don't recognise.”
Hyperion
“I can help with that. I'll verify two details, then read the transaction back to you.”
Runs inside the bank's own network, where the regulation says the data has to stay.
Caller
“I need to report damage to my car.”
Hyperion
“I'm sorry to hear that. I'll open the claim now — where and when did it happen?”
First notice of loss taken end to end, documented and routed — installed locally where the policy demands it.
Caller
“Do you have a room for two nights from Friday?”
Hyperion
“We do. A double with sea view is free — shall I hold it for you?”
Reservations taken mid-service, in the caller's language, without a missed booking.
Caller
“My order still hasn't arrived.”
Hyperion
“Let me check. It left the warehouse yesterday and is out for delivery today — shall I text you the tracking link?”
Order status, returns and delivery questions handled around the clock.
Caller
“I'm calling about the flat in the listing.”
Hyperion
“It's still available. Viewings are Saturday morning — shall I put you down for 11:00?”
Every inquiry qualified and scheduled for a viewing before the listing goes cold.
05Languages
45+ languages. At home in all of them.
Hyperion detects the caller's language on the first sentence and can switch mid-call. Pick one.

06The arithmetic
What does silence cost you?
Move the sliders. The number below is revenue that currently rings out into nothing — every month.
Recoverable revenue / month€9,750
07Enterprise
Install it behind your firewall.
For health, banking and insurance, where the data legally cannot leave the building. Hyperion installs on top of the Asterisk / FreePBX you already run.
Runs on your infrastructure
Deployed onto your current Asterisk / FreePBX through our own bridge. No switchboard change, no number porting.
Every model can run locally
Recognition and synthesis are ours, so they can be executed on your hardware — including with the network unplugged.
Nothing is retained
No audio and no transcripts are kept on our side. In a self-hosted install nothing reaches us in the first place.
Volume pricing
A setup fee plus a per-minute rate, built for high call volumes and negotiated per contract.

In production since September 2025: 400,000 calls and roughly 500,000 minutes handled, start to finish, without a human operator.
08Data & trust
Nothing is kept. Nothing leaves.
Zero data retention
We keep no audio and no transcripts. What is recorded, and where it is kept, is entirely your decision — including not at all.
It runs on your servers
Recognition, synthesis and the telephony bridge can all run inside your own network, with no internet connection at all.
Built for the audit
A self-hosted install answers the data-residency requirement directly, rather than promising to handle it somewhere else.
No third party in the loop
Our own models can carry the whole call. Where you prefer an external provider, that stays your choice — not a dependency.
09Questions
Asked, answered.
Will callers know they're talking to an AI?
Hyperion sounds natural — pauses, warmth, manners included. It identifies itself as an assistant whenever asked, and disclosure is configurable to match local regulations. What callers notice most is that they were helped in seconds.
How long does setup take?
Most businesses go live within a week. A simple reception setup can be live the same afternoon — we configure the agent with you, test it together, and only then switch it on.
Can I keep my phone number?
Yes. You simply forward your existing number to Hyperion — always, after a few rings, or outside business hours. You stay in control of the routing at all times.
What happens to my data?
Recordings and transcripts belong to you. We operate in line with GDPR and KVKK, offer EU hosting options, and delete data on request. No call data is ever sold or used to train third-party models.
What if a caller really needs a human?
You define the rules: VIP callers, emergencies, complex complaints — Hyperion transfers warmly to the right person with a live summary, or takes a detailed message when no one is available.
Which languages does it speak?
45+ languages, including German, English, Turkish, French, Spanish, Italian and Arabic. Hyperion detects the caller's language automatically and can switch mid-call.
