Voice agents for consumer durables

AI agents that answer your service helpline, call owners before a warranty ends, and help your technicians at the customer's door, in more than 25 languages. They work from the registered product, the warranty and the service history, and finish the task during the call: raise the ticket, book the visit, reserve the part, send the payment link. Tilicho builds and runs them inside your own Google Cloud project, starting from accelerators for 23 consumer-durables use cases.

Where to start

Three agents on one service record

The helpline, the field and the warranty base, each with its own agent. All three read and write the same customer, product and ticket record, so one integration supports all three.

The helpline raises the ticketThe technician fixes it, or turns it into a paid repairThe warranty agent renews cover before it ends

One call

Before, during and after the call

1

Before the ring

The number is matched to the customer's registered products: model, serial, install date, warranty or AMC status, open tickets and past visits. Calling hours and consent are checked before an outbound dial.

2

During the call

The agent confirms the product, takes the symptom or the error code, tries the fix the customer can do, and raises the ticket, books the slot or sends the payment link while the customer is on the line.

3

When a person is needed

A smell of gas, sparks or burning, a repeat failure, a refund demand or any request for a person goes to your team live, with the product, the history and the summary on screen.

4

After hang-up

Ticket, outcome tag, transcript and recording are written to your CRM and service system. The visit reminder, the payment follow-up or the feedback call is scheduled.

Use cases

23 accelerators for consumer durables

Each agent starts from an accelerator, so a use case is on live calls in about one month.

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 registered owner before it names the product.

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 product, the problem or the plan.

Calling window
12 am9 am9 pm12 am

Calling hours

Offer calls are placed only inside the hours you set, for example 9 am to 9 pm. The helpline answers at any hour.

Consent and DND

Offer calls go only to registered owners who have consented, and numbers on the do-not-disturb registry are checked.

Data for technicians

A technician hears a customer's details only for a job assigned to them. A mobile number alone opens nothing.

Personal data

PII is masked in transcripts and logs. Access is by role. The agent never asks for a card number, OTP or password.

Your own cloud project

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

Safety first

A smell of gas, sparks or burning: the agent tells the customer to switch off at the mains and puts the call through to a person.

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 a serial number.
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 handlingKitchens, a machine in its spin cycle, a shop floor. 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
Product 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 product, the history, the transcript summary and the captured details before speaking.

Closing the loop

An analyzer agent keeps each ticket open until it reaches an end state: fixed, paid, renewed, or handed to your team.

Questions

Common questions

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.

What if the customer registered with another number?

The agent asks for the serial number from the product label, or the PIN code and the name, and finds the product that way before it goes further.

Can anyone get a customer's details by calling the technician line?

No. The technician is identified by the registered phone and technician ID, and the agent reads out a customer's details only for a job assigned to that technician.

What happens when the customer wants a person?

The call is transferred live to your team with the product, the history and the summary, so the customer does not repeat the case. You decide which cases always go to a person, such as safety issues and refund demands.

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 telephony, CRM or service system?

No. The agent connects to your existing numbers and systems. There are more than 50 integrations, and other systems, such as SAP, are connected through their APIs during setup.
