Coaching Institute Generated 40% More Leads with AI Voice Bot

The Challenge

A competitive exam coaching institute in Delhi was missing 50% of after-hours student inquiries and weekend calls. Their manual follow-up process was slow, with an average response time of 6 hours for missed calls.

Our Solution

We built an AI voice bot that answers all incoming calls 24/7, provides course information, answers FAQs about fees and batches, schedules counseling calls, and captures lead details automatically in their CRM.

How We Built It

  1. 1

    Recorded and analysed 200+ real calls between students and counsellors to identify the most common questions, objections, and conversation flows.

  2. 2

    Built a custom voice bot with a warm, conversational tone in Hindi and English using a voice AI pipeline with ASR, LLM-based dialogue management, and natural TTS.

  3. 3

    Created a structured course database covering all programmes, batch schedules, fee structures, and eligibility criteria so the bot could answer accurately.

  4. 4

    Integrated with a telephony provider to handle inbound calls to the institute's existing phone number, with the bot answering after 2 rings.

  5. 5

    Designed a lead capture flow: the bot collected the caller's name, phone, course interest, class, and preferred batch time, then wrote the data to the CRM.

  6. 6

    Set up a callback scheduler: if the prospect wanted to speak to a counsellor, the bot booked a timeslot and sent a notification to the counselling team.

Integration & Architecture

The voice bot was connected to the institute's existing phone number via Exotel SIP trunking. Inbound calls were routed to the bot after 2 rings. Lead data was pushed to their CRM (Zoho) via API, and counselling callbacks were created as CRM tasks assigned to the next available counsellor.
