Voice agents for education

AI agents that call every admissions enquiry within minutes, help applicants finish the form and pay the fee, and answer students and parents at any hour, in Hindi, English, Hinglish and the Indian languages, more than 25 languages in all. They work from the enquiry, the application and the student record, and finish the task during the call: book the counselling session, send the upload or payment link, raise the request. Tilicho builds and runs them inside your own Google Cloud project, starting from accelerators for 24 education use cases.

Where to start

Three agents on one student record

The enquiry, the application and the enrolled student, each with its own agent. All three read and write the same student record, so one integration supports all three.

Outbound

Admissions enquiry follow-up

The agent calls every enquiry within minutes of the form. It confirms the course, the intake and the budget, answers from your prospectus, and books a counselling session or a campus visit.

  1. Enquiry called within minutes, the parent if the student is under 18
  2. Course, intake, city and budget confirmed
  3. Fees, eligibility and entrance exams answered
  4. Counselling session or campus visit booked on WhatsApp
Measured byTime to first call, enquiries to counselling sessions

Application and fee completion

The agent calls applicants who stopped midway. It states what is pending, the form, a document or the fee, helps with what is stopping them, and sends the link before the deadline.

  1. Saved but unsubmitted applications picked up daily
  2. Pending step stated: form, documents or fee
  3. Questions answered, such as a document not yet issued
  4. Upload or payment link on WhatsApp, follow-up until done

Inbound

Student and parent helpline

Students and parents call about fees, the timetable, results, the hostel or the bus. The agent answers from your records at any hour, in the caller's language, and raises a request when your staff are needed.

  1. Caller matched to the student or the parent
  2. Answered from fee, timetable, results, hostel and transport records
  3. Links and documents sent on WhatsApp

One call

Before, during and after the call

1

Before the ring

The number is matched to the enquiry, the application or the student record: course, intake, stage, pending documents, fees due and past calls. Calling hours, consent and the student's age are checked before an outbound dial.

2

During the call

The agent confirms who it is speaking to, answers from your prospectus and records, and books the session, sends the upload or payment link or raises the request while the caller is on the line.

3

When a person is needed

A fee concession, a complaint about staff, a disputed result or any request for a person goes to your team live, with the record and the summary on screen. A student who sounds distressed or mentions self-harm is handed to a person at once.

4

After hang-up

Stage, outcome tag, transcript and recording are written to your CRM and student system. The reminder, the payment follow-up or the next call is scheduled.

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 student, or to the parent or guardian for a student under 18, before it names the application or the fees.

2

Who is calling and why

Your institution'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 course, the application or the fees.

Calling window
12 am9 am9 pm12 am

Calling hours

Admissions and fee 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

Admissions calls go to people who enquired or applied. Promotional calls are checked against TRAI's National Customer Preference Register (DND).

Students under 18

For a student under 18 the agent speaks to the parent or guardian on record, and the student's personal data is used with the parent's or guardian's consent.

Personal data

PII is masked in transcripts and logs. Access is by role. Consent, retention and access follow the Digital Personal Data Protection Act, 2023. 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 student data stay in your storage.

A student in distress

A student who sounds distressed or mentions self-harm is handed to a person at once.

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 caller is still reading out an application 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 handlingA hostel corridor, a coaching centre between classes, traffic outside the school gate. The agent stays clear without asking the caller 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 students. This is fixed before the build, since reply time cannot be tuned afterwards.

Language mirroring

The agent mirrors the caller turn by turn, so it follows the caller'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
Student 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 counsellor sees the record, the transcript summary and the captured details before speaking.

Closing the loop

An analyzer agent keeps each case open until it reaches an end state: enrolled, paid, answered, 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, which matters when the student speaks English and the parent prefers Telugu or Marathi.

Does the agent call students under 18?

For a student under 18 the agent speaks to the parent or guardian on record. It confirms it has the right person before it names the application or the fees.

Can anyone get a student's marks or fees by calling?

No. The caller is matched to the registered number and confirms a detail such as the roll number or application number before the agent reads out anything from the record.

What happens when the student or parent wants a person?

The call is transferred live to your counsellor or office with the record and the summary, so the family does not repeat the case. You decide which cases always go to a person, such as fee concessions and complaints. A student who sounds distressed is handed to a person at once.

Where are recordings and student data kept?

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

Do we have to change our CRM, student system or telephony?

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