🎙️ Running in production, in 30+ languages

AI voice agent development
in the language your user actually speaks.

A push notification gets ignored. A text message gets ignored. A voice that says "your child's bus is eight minutes away" in the language spoken at home does not. We build that — and it's live right now in a patent-filed product on both app stores.

Why voice, and why multilingual

Text assumes your user reads. Voice doesn't.

🔕

Notifications get ignored

People have hundreds of unread notifications. A banner competes with every other app on the phone. A voice message arriving at the right moment does not.

🗣️

English isn't universal

In India, the Gulf and Southeast Asia, the person using your product often reads a different language at home than your app was written in. Voice removes that barrier.

👀

Some moments are hands-free

Driving, cooking, working, walking a child to a gate. Voice reaches people in situations where reading a screen is not an option.

👵

Not everyone reads easily

Older users, users with low literacy, users with visual impairment. Voice is the most inclusive interface there is, and it's usually the last one anyone builds.

What we build

Triggered voice, not a novelty demo

Something happens in your system, and the right person hears the right sentence in the right language. That's the whole product.

🚨

Event-triggered alerts

A vehicle arrives, a payment fails, a delivery is delayed, an emergency button is pressed. The event fires, the voice message is generated from live data and delivered.

Live in production: bus arrival and SOS alerts

Scheduled reminders

Appointment tomorrow, subscription renewing, medication due, document expiring. Cron picks the recipients, the voice layer handles the language.

Cuts no-shows without adding staff

📞

Outbound voice calls

For people who don't have your app, or don't open it. The same pipeline places a call and speaks the message, with delivery status logged back.

Reaches users your app never will

🔢

IVR and menu flows

"Press 1 to confirm, 2 to reschedule." Structured voice interaction where the options are fixed and the outcome writes straight back into your database.

Confirmations without a call centre

📱

In-app voice playback

A speaker icon next to content that reads it aloud, in the user's language. The cheapest accessibility win available in most apps.

Flutter and web, cached for repeat plays

🌐

Full app localisation

Voice is pointless if the interface is still monolingual. We do the whole layer — strings, layout, right-to-left, number and date formats, then voice on top.

The one that's in production

Parents hear about the school bus in the language they speak at home.

We built a child-safety platform for school transport. Live GPS, one-tap SOS, secure QR boarding — and the part parents actually mention is the voice.

When a bus is approaching, the parent doesn't get a banner they'll swipe away. They hear a sentence with the bus number and the minutes, in Hindi or English depending on who is listening. Two parents on the same route, on the same alert, hear two different languages. Neither of them configured anything.

It's patent-filed in India, live on Google Play and the App Store, and it runs every school day. That's the difference between a voice demo and a voice product.

How it works

Five steps between an event and a voice

None of this is exotic. What makes it work in production rather than in a demo is the unglamorous middle: caching so it isn't expensive, fallbacks so it doesn't fail silently, and logging so you know it actually reached someone.

We built this into a live product before selling it to anyone, which is why the edge cases are already handled.

1

Event fires

Bus enters a geofence, payment fails, SOS pressed, cron reaches a reminder. Your existing system already knows — we hook into it rather than replacing it.

2

Language is chosen per recipient

User preference first, then device locale, then region default, then a configured fallback. Decided per person, so one event can produce five languages.

3

Sentence is built from live data

Templates hold the fixed phrasing per language; live values — bus number, minutes, amount, name — are inserted. Grammar handled per language, not translated word by word.

4

Audio generated, then cached

Neural text-to-speech produces the clip. Repeated phrases are cached so you don't pay to regenerate "your bus is arriving" ten thousand times a month.

5

Delivered, and logged

In-app playback, an outbound call, or WhatsApp audio — whichever reaches that user. Every send is logged with status, so silent failures become visible instead of invisible.

What we don't build — read this before you enquire

"AI voice agent" often means a bot that holds a live phone conversation with your customer. That is not what we do, and we'd rather you know now than three weeks into a project.

  • Real-time two-way conversation — a caller talking to an AI that listens and replies live. Not our strength. Specialists exist and we'll point you at them.
  • Voice cloning of a specific person — technically possible, ethically and legally messy, and we don't take that work.
  • Speech recognition at scale — transcribing thousands of hours of audio is a different discipline with different tooling.

What we do build is the part most businesses actually need and almost nobody does well: the right message, in the right language, reaching the right person at the right moment — reliably, cheaply, and in production.

Three ways to start

Text-to-speech usage is billed by the provider on your own account and is usually a small fraction of the build cost. Caching keeps it that way.

Questions before you commit

AI voice, answered plainly

Do you build real-time conversational voice agents that talk back?+
No, and we'd rather tell you here than after you sign. Real-time two-way voice conversation isn't our strength. What we do build, and have live in production, is triggered and scheduled multilingual voice: an event happens, the right message is generated in the right language, and it reaches the person by app, call or WhatsApp. For alerts, reminders, confirmations and status updates that covers the large majority of real business need.
How many languages can the AI voice speak?+
Over 30, using neural voices that sound close to human rather than the flat robotic output people associate with text-to-speech. In production we run Hindi and English side by side with automatic detection, plus French, Spanish and Haitian Creole in another product. The same pipeline extends to Arabic, Malay, Tamil, Bengali, Marathi and many more — adding a language is a configuration change, not a rebuild.
How does automatic language detection work?+
The system decides per recipient rather than per app. It uses the language the user selected, falls back to their device locale, then a region default, then a configured default. So two people receiving the same alert from the same event hear it in two different languages, without either of them configuring anything.
How much does AI voice agent development cost?+
A voice alert pipeline for an existing app starts around $1,800 as a fixed-price build. A full multilingual system with language detection, multiple delivery channels and an admin console starts around $4,500. Ongoing work can instead be covered by a dedicated AI developer at $999 a month. The recurring text-to-speech cost is billed by the provider on your account and, with caching, is usually a small fraction of the build cost.
Can voice be added to an app that's already live?+
Yes, and that's how we did it ourselves. Both of our own products had AI added after launch rather than being designed around it. We integrate into existing Flutter and PHP products without a rewrite, and we keep the voice layer separate so it can be switched off per user or per event without touching the rest of the app.
Does AI voice pass Google Play and App Store review?+
Voice itself is rarely the problem. What gets AI apps rejected is missing safety infrastructure around it: no AI disclosure, no moderation, no reporting, unclear permissions. We know because Google Play rejected one of our AI apps and we had to build all of it to get approved. Disclosure, permission handling and audit logging are now included by default.
Is the voice pre-recorded or generated?+
Generated, which is the point. Pre-recorded audio can't say a specific bus number, a specific delay in minutes or a specific customer name. Generated voice builds the exact sentence from live data, then caches the fixed parts so repeated phrases cost nothing to regenerate.
Who owns the voice pipeline and the code?+
You do. IP assignment is signed before work begins, code lives in your repository from the first commit, and the provider account is yours — so the voice keeps working whether or not we're still involved. We don't build lock-in.

Who needs to hear from your app,
and in which language?

Free 30-minute call. We'll tell you honestly whether voice is worth it for your use case — sometimes a better-written notification is the cheaper answer.
