Online retail, marketplaces and travel bookings

Voice agents for e-commerce and travel

AI agents that confirm cash-on-delivery orders before dispatch, call customers when a delivery fails, answer your helpline about orders and bookings, and call travellers when a booking needs attention, in more than 25 languages. They work from the order or the booking and finish the task during the call: correct the address, book the pickup, rebook the trip, send the payment link. Tilicho builds and runs them inside your own Google Cloud project, starting from accelerators for 25 e-commerce and travel use cases.

Where to start

Three agents on one customer record

Orders, the helpline and travel bookings, each with its own agent. All three read and write the same customer, order and booking record, so one integration supports all three.

The order or booking is confirmedIt is delivered, or the trip goes aheadThe customer reviews it, and orders or books again

One call

Before, during and after the call

1

Before the ring

The number is matched to the customer's orders and bookings: items, payment mode, courier status, travel dates and open tickets. Calling hours and consent are checked before an outbound dial.

2

During the call

The agent confirms the order or the booking, takes the change the customer asks for, and corrects the address, books the pickup, rebooks the trip or sends the payment link while the customer is on the line.

3

When a person is needed

A fraud concern, a refund dispute, a traveller stuck at an airport or station, or any request for a person goes to your team live, with the order or booking, the history and the summary on screen.

4

After hang-up

Status, outcome tag, transcript and recording are written to your order or booking system and CRM. The courier update, the payment follow-up or the review call is scheduled.

Use cases

Compliance

How every call opens

The opening is fixed in the script. It is the same on every call, in every language.

1

Right person

On an outbound call the agent confirms it is speaking to the customer who placed the order, or the lead traveller, before it names the order or the trip.

2

Who is calling and why

Your brand's name and the purpose of the call, in the words your team approved.

3

AI assistant, recorded call

The agent says it is an AI assistant and that the call is recorded.

4

The conversation

Only then does the script move to the order, the delivery or the booking.

Calling window
12 am9 am9 pm12 am

Calling hours

Offer calls, such as cart recovery and repeat-purchase offers, are placed only inside the hours you set, for example 9 am to 9 pm. The helpline answers at any hour.

Consent and DND

Promotional calls go only to customers who have consented, and numbers on TRAI's National Customer Preference Register (DND) are checked first.

Payments by link

The agent never takes a card number, OTP or UPI PIN on the call. It sends a secure payment link from your payment gateway.

Personal data

PII is masked in transcripts and logs. Access is by role. Consent and retention are set up for the Digital Personal Data Protection Act, 2023.

Your own cloud project

The agent runs in your Google Cloud project, in region. Recordings and customer data stay in your storage.

Changes to an order

The agent changes an address, an order or a booking only for the confirmed customer, and reads the change back before it is saved.

Engineering

How the agent is built

Speech to speechOne model hears and speaks. The fastest replies, and the caller's tone carries through. The default for live calls.
Caller audioGemini 3.8 LiveAgent audio
CascadedThree models in sequence. Each step can be inspected, and the model cost per minute is lower. Used where the script is strict.
Caller audioChirp 3 speech to textGemini 3.8 FlashGemini 3.8 Flash TTSAgent audio

One turn of a call

CallerAgent Speech detected (VAD)A pause, not the endEnd of turnAgent repliesCaller interruptsAgent stopsAgent answers the new point
Voice activity detection (VAD)Separates the caller's speech from line noise and silence. Only speech is sent to the model, so silence is neither processed nor paid for.
End-of-turn detectionTells a pause in the middle of a sentence from the end of it, so the agent does not reply while the customer is still reading out an address or a PNR.
Barge-inWhen the caller interrupts, the agent stops speaking at once and the words it did not say are dropped from the conversation.
Answering machine detectionDecided from the audio in the first seconds, before a language model is involved, so voicemail is not counted as a contact.
Noise handlingA busy road, a market, a railway platform, an airport gate. The agent stays clear without asking the customer to repeat.
Context compressionA live model re-reads the call so far on every turn. Older turns are summarised, so reply time and cost stay flat on long calls.

Reliability

In-region deployment

The agent runs in the Google Cloud region closest to your customers. This is fixed before the build, since reply time cannot be tuned afterwards.

Language mirroring

The agent mirrors the customer turn by turn, so it follows the customer's language and not a setting.

Supervisor and task agents

A supervisor routes to small agents that share the state of the call. The script grows by adding agents.

Supervisor
Order lookupBookingPayment

Model fallback

A health-checked fallback model in the same region takes over mid-call, with the state of the call intact.

Warm transfer

Your team member sees the order or booking, the history, the transcript summary and the captured details before speaking.

Closing the loop

An analyzer agent keeps each order or booking open until it reaches an end state: confirmed, delivered, rebooked, refunded, or handed to your team.

Questions

Common questions

Which businesses are these agents for?

Online retailers and D2C brands, marketplaces, quick commerce, online travel agencies, airlines, hotel groups, tour and holiday operators, and bus and rail booking platforms.

Which languages does the agent speak?

More than 25 languages: Hindi, Hinglish and the Indian languages, and for other markets Bahasa Indonesia, Malay, Thai, Vietnamese, Filipino, Arabic, Spanish, French, German and Portuguese among others. The agent switches language during the call when the customer does.

How do the calls reduce returns to origin?

The agent confirms each COD order and its address before dispatch, so orders the customer did not mean to place are cancelled before they ship. When a delivery fails, it calls the same day and books a new date or a corrected address, so the parcel is attempted again instead of going back.

Does the agent take payments on the call?

No. It never asks for a card number, OTP or UPI PIN. It sends a payment link from your payment gateway on WhatsApp or SMS, and confirms on the call when the payment lands.

What happens when the customer wants a person?

The call is transferred live to your team with the order or booking, the history and the summary, so the customer does not repeat the case. You decide which cases always go to a person, such as fraud concerns, refund disputes and travellers stuck at an airport.

Where are recordings and customer data kept?

In your own Google Cloud project and your storage. Tilicho runs the agent inside that project.

Do we have to change our store, shipping or booking system?

No. The agent connects to your existing numbers and systems. There are more than 50 integrations, including Shopify, and other systems, such as your shipping platform or booking engine, are connected through their APIs during setup.
